Description
技术领域
本发明总体涉及用于从各种地下地层(例如含烃地层)生产烃、氢和/或其它产品的方法和系统。特别地，某些实施例涉及用于在就地转化过程期间加热地层的一部分的闭环循环系统。
背景技术
从地下地层中所获得的烃通常用作能量源、原料以及消费品。对可用烃资源衰竭的关注和对产出烃的总体质量下降的关注，导致开发出了用于更有效地回收、处理和/或使用可用烃资源的方法。就地处理可用于从地下地层移出烃材料。可能需要改变地下地层中的烃材料的化学和/或物理性能，以使烃材料更容易从地下地层移出。化学和物理变化可包括地层中烃材料的生成可移出流体的就地反应、成分变化、溶解度变化、密度变化、相变和/或粘度变化。流体可以是，但是不限于，气体、液体、乳状液、浆液和/或具有与液体流类似的流动特性的固体颗粒流。
许多不同类型的井或井眼可用于使用就地热处理方法来处理含烃地层。在一些实施例中，竖直和/或基本上竖直的井用于处理地层。在一些实施例中，水平或基本水平的井(诸如J形井和/或L形井)和/或u形井用于处理地层。在一些实施例中，水平井、竖直井和/或其它组合的组合用于处理地层。在某些实施例中，井延伸穿过地层的上覆岩层到达地层的含烃层。在一些情况下，井中的热量损失到上覆岩层中。在一些情况下，用于支承水平井眼或u形井眼中的加热器和/或生产设备的地面和上覆岩层的基础结构尺寸和/或数量很大。
Sandberg等人的美国专利7,575,052描述了一种就地热处理方法，该方法采用循环系统加热一个或多个处理区。循环系统可使用经过地层中的管道的已加热的液态传热流体以将热传递至地层。
Vinegar等人的美国专利申请公开2008-0135254描述了一种用于就地热处理过程的系统和方法，该就地热处理过程采用循环系统来加热一个或多个处理区。循环系统使用经过地层中的管道的已加热的液态传热流体以将热传递至地层。在一些实施例中，管道布置在至少两个井眼中。
Nguyen等人的美国专利申请公开2009-0095476描述了一种用于地下地层的加热系统，该加热系统包括位于地下地层中的开口内的导管。绝缘导体位于导管中。材料在导管中、在绝缘导体的一部分与导管的一部分之间。该材料可以是盐。该材料在加热系统的工作温度下是流体。热从绝缘导体传递至流体，从流体传热递至导管，以及从导管传递至地下地层。
对于提出用于从含烃地层中经济地产出烃、氢和/或其它产品的方法和系统已经付出了巨大的努力。但是，目前仍然存在许多不能从其中经济地产出烃、氢和/或其它产品的含烃地层。因而，仍需要改进的方法和系统，以相对于采用地面基设备回收烃的方法而言，减少用于处理地层的能量消耗、减少来自处理过程的排出物、便于加热系统的安装和/或减少损失到上覆岩层的热损失。

在一些实施例中，本发明提供了一种加热地下地层的方法，该方法包括：将第二传热流体引入加热器的第一通道中以预热加热器；将第一传热流体引入加热器的第二通道中；以及在加热器的温度足以确保第一传热流体的流动性之后消除或减少第二传热流体流入第一通道中的流动。
在一些实施例中，本发明提供了一种加热地下地层的系统，该系统包括：至少一个流体循环系统，所述至少一个流体循环系统构造用于将热传热流体提供给地层中的多个加热器；以及地层中的多个加热器，所述多个加热器与循环系统联接，其中加热器中的至少一个包括：第一导管；位于第一导管中的第二导管；以及第一流动转换器，该第一流动转换器构造用于使得流过第二导管的流体流过第一导管与第二导管之间的环形区域。
在一些实施例中，本发明提供了一种加热地下地层的方法，该方法包括：使第一传热流体循环通过位于地下地层中的加热器，以将加热器的温度升高到确保加热器中第二传热流体的流动性的温度；停止使第一传热流体通过加热器的循环；使第二传热流体循环通过位于地下地层中的加热器，以升高邻近加热器的加热处理区的温度。
在另外的实施例中，特定实施例的特征可与其它实施例的特征组合。例如，一个实施例的特征可与任一其它实施例中的特征组合。
在另外的实施例中，使用在此所述的方法、系统或加热器中的任一个来实现处理地下地层。

术语“井眼”是指通过钻井或将导管插入地层中而在地层中形成的孔。井眼可具有基本上圆形的横截面或其它横截面形状。如在此所使用的，术语“井”和“开口”在指地层中的开口时可与术语“井眼”互换使用。
可以各种方式处理地层，以生产出许多不同的产品。不同的阶段或过程可用于在就地热处理过程期间处理地层。在一些实施例中，地层的一个或多个部段进行溶解采矿，以从这些部段中移出可溶矿物。可在就地热处理过程之前、期间和/或之后对矿物进行溶解采矿。在一些实施例中，进行溶解采矿的一个或多个部段的平均温度可被保持在约120℃以下。
在一些实施例中，一个或多个地层部分被加热，以便从这些部段移出水和/或从这些部段中移出甲烷和其它挥发性烃。在一些实施例中，在移出水和挥发性烃的过程中，平均温度可从环境温度上升到约220℃以下的温度。
在一些实施例中，地层的一个或多个部段被加热到允许地层中的烃运动和/或降粘的温度。在一些实施例中，地层的一个或多个部段的平均温度可被升高到这些部段中的烃流动的温度(例如，从100℃到250℃范围内的温度、从120℃到240℃范围内的温度或者从150℃到230℃范围内的温度)。
在一些实施例中，一个或多个部段被加热到允许在地层中进行热解反应的温度。在一些实施例中，地层的一个或多个部段的平均温度可被升高到烃在这些部段中的热解温度(例如从230℃到900℃范围内的温度、从240℃到400℃范围内的温度或者从250℃到350℃范围内的温度)。
利用多个热源加热含烃地层可在热源周围形成热梯度，所述热源将地层中烃的温度以期望的加热速度升高到期望的温度。温度升高经过用于期望产品的流动温度范围和/或热解温度范围的速率可影响从含烃地层产生的地层流体的质量和数量。将地层温度缓慢升高经过流动温度范围和/或热解温度范围可允许从地层中生产出高质量、高API重力指标的烃。将地层温度缓慢升高经过流动温度范围和/或热解温度范围可允许移出存在于地层中的大量烃以作为烃产品。
在一些就地热处理的实施例中，代替将温度缓慢地加热经过温度范围的是将地层的一部分加热到期望的温度。在一些实施例中，期望的温度是300℃、325℃或350℃。可选择其它温度作为期望的温度。
叠加来自热源的热允许在地层中相对快速有效地建立期望温度。从热源输入地层中的能量可被调节以使地层中的温度基本上保持在期望温度。
流动和/或热解产品可通过生产井从地层生产出。在一些实施例中，一个或多个部段的平均温度升高到流动温度，并且烃从生产井生产出。在生产之后，由于流动降低到选定值以下，一个或多个部段的平均温度可被升高到热解温度。在一些实施例中，在达到热解温度之前不进行大量生产的情况下，一个或多个部段的平均温度可被升高到热解温度。包含热解产品的地层流体可通过生产井生产出。
在一些实施例中，一个或多个部段的平均温度可被升高到足够高的温度，以便允许在流动和/或热解之后进行合成气体生产。在一些实施例中，烃可被升高至足够高温度，以便在达到足以允许进行合成气生产的温度之前不进行大量生产情况下允许进行合成气生产。例如，合成气体可在从约400℃到约1200℃、从约500℃到约1100℃或者从约550℃到约1000℃的温度范围内产生。合成气产生流体(例如蒸汽和/或水)被引入到这些部段中以产生合成气。合成气可从生产井中生产出。
溶解采矿、挥发性烃和水的移出、使烃流动、热解烃、产生合成气和/或其它过程可在就地热处理过程中进行。在一些实施例中，一些过程可在就地热处理之后进行。这些过程可包括，但不限于，从已处理的部段回收热、将流体(例如，水和/或烃)存储在先前已处理的部段中和/或将二氧化碳隔绝在先前已处理的部段中。
图1描绘了用于处理含烃地层的就地热处理系统的一部分的一个实施例的示意图。该就地处理系统可包括障壁井100。障壁井用于在处理区周围形成障壁。所述障壁抑制流体流入和/或流出处理区。障壁井包括，但是不限于，脱水井、真空井、俘获井、注入井、灌浆井、冷冻井或它们的组合。在一些实施例中，障壁井100是脱水井。脱水井可去除液态水和/或阻止液态水进入待加热的地层部分或正在被加热的地层。在图1所示的实施例中，障壁井100显示为仅沿热源102的一侧延伸，但是障壁井通常环绕所使用的或将要使用的所有热源102，以加热地层的处理区。
热源102设置在地层的至少一部分中。热源102可包括导电材料。在一些实施例中，加热器例如为绝缘导体、导体在导管中的加热器、地表燃烧器、无焰分布式燃烧器和/或自然分布式燃烧器。热源102还可包括其它类型的加热器。热源102向地层的至少一部分提供热，以加热地层中的烃。能量可通过供给管线104供应给热源102。供给管线104可根据一种或多种用于加热地层的热源而在结构上有所不同。用于热源的供给管线104可传输用于导电材料或电加热器的电，可传输用于燃烧器的燃料，或者可传输在地层中循环的热交换流体。在一些实施例中，用于就地热处理过程的电可由一个或多个核电站提供。使用核动力可使得降低或消除从就地热处理过程释放的二氧化碳。
加热地层可引起地层的渗透性和/或孔隙率增大。渗透性和/或孔隙率的增大可通过由于水的汽化和移出、烃的移出和/或断裂的形成而使地层中的矿体减小而产生。由于地层的增大的渗透性和/或孔隙率，流体可更容易地在地层受热部分中流动。由于增大的渗透性和/或孔隙率，地层受热部分中的流体可运动通过地层相当长的距离。相当长的距离根据各种因素可以是1000m以上，该各种因素诸如是地层的渗透性、流体的性质、地层的温度和允许流体运动的压力梯度。流体在地层中行进相当长距离的能力允许生产井106在地层中相对远地间隔开。
生产井106用于从地层移出地层流体。在一些实施例中，生产井106包括热源。生产井中的热源可在生产井处或生产井附近加热地层的一个或多个部分。在一些就地热处理过程的实施例中，由每米生产井从生产井提供给地层的热量小于由加热地层的每米热源提供给地层的热量。从生产井提供给地层的热可通过汽化和移出生产井附近的液相流体和/或通过由形成大量和/或极微小的断裂而增大生产井附近的地层的渗透性来增大生产井附近的地层渗透性。
在一些实施例中，生产井106中的热源允许从地层中移出地层流体的汽相。在生产井处或通过生产井提供热可用于：(1)在该生产流体邻近上覆岩层在生产井中运动时抑制该生产流体的冷凝和/或逆流；(2)增加输入到地层中的热；(3)与没有热源的生产井相比提高生产井的产率；(4)抑制生产井中高碳数(C6及以上)化合物的冷凝；和/或(5)增大生产井处或生产井附近的地层的渗透性。
地层中的地下压力可对应于在地层中产生的流体压力。随着地层的受热部分中的温度升高，受热部分中的压力可由于就地流体的热膨胀、增加的生成流体和水的汽化而增大。控制从地层移出流体的速率可允许控制地层中的压力。地层中的压力可在很多不同的位置处确定，诸如在生产井附近或在生产井处、在热源附近或在热源处、或在监控井处。
在一些含烃地层中，从地层生产烃受到抑制，直到已经使地层中的至少一些烃流动和/或热解。当地层流体具有选定质量时，地层流体可从地层产出。在一些实施例中，选定质量包括至少约20°、30°或40°的API重力指标。直到使至少一些烃流动和/或热解，抑制生产才可加快重烃向轻烃的转化。抑制初期产量可使从地层产出的重烃的量最小。生产大量重烃可能需要昂贵的设备和/或缩短生产设备的寿命。
在一些实施例中，可允许增加由在地层中产生的流动流体、热解流体或其它流体的膨胀所产生的压力，尽管通向生产井106的开放路径或任何其它压力降可能仍然不存在于地层中。可允许流体压力朝向岩石静压力增加。含烃地层中的断裂可在流体接近岩石静压力时形成。例如，可在地层的受热部分中从热源102至生产井106形成断裂。受热部分中断裂的产生可释放该部分中的一些压力。地层中的压力可能不得不保持低于选定压力以便抑制不想要的生产、上覆岩层或下伏岩层的断裂和/或烃在地层中的焦化。
在达到流动和/或热解温度且允许从地层进行生产之后，地层中的压力可发生变化，用于改变和/或控制产出的地层流体的成分、用于控制地层流体中可冷凝流体相对于不可冷凝流体的百分比、和/或用于控制正在产出的地层流体的API重力指标。例如，降低压力可导致产出较大的可冷凝流体组分。可冷凝流体组分可含有较大百分比的烯烃。
在一些就地热处理过程的实施例中，地层中的压力可保持足够高以促使产出API重力指标大于20°的地层流体。在地层中保持增大的压力可在就地热处理期间抑制地层塌陷。保持增大的压力可减少或消除对在地表处压缩地层流体以将收集管道中的流体输送到处理设备的需要。
令人惊讶的是，在地层的受热部分中保持增加的压力可允许产生质量提高且相对低分子量的大量烃。压力可保持成使得产出的地层流体具有极小量的所选碳数以上的化合物。所选碳数可以是至多25、至多20、至多12或至多8。一些高碳数化合物可夹带在地层中的蒸气中并且可与蒸气一起从地层移出。在地层中保持增大的压力可抑制在蒸气中夹带高碳数化合物和/或多环烃化合物。高碳数化合物和/或多环烃化合物可在地层中在相当长时间保持为液相。相当长时间可为化合物提供足够长的时间进行热解以形成低碳数化合物。
从生产井106产出的地层流体可通过收集管道108输送到处理设备110。地层流体还可从热源102产出。例如，流体可从热源102产出以控制邻近热源的地层中的压力。从热源102产出的流体可通过生产管或管道输送到收集管道108，或者产出流体可通过生产管或管道直接输送到处理设备110。处理设备110可包括分离单元、反应单元、改质单元、燃料室、涡轮、存储容器和/或其它用于处理产出的地层流体的系统和单元。处理设备可将从地层产出的烃的至少一部分形成运输燃料。在一些实施例中，运输燃料可以是航空燃料(jet fuel)，诸如JP-8。
在某些实施例中，热源、热源动力源、生产设备、供给管线和/或其它热源或生产支承设备布置在隧道(tunnels)中，以使得较小尺寸的热源和/或较小尺寸的设备能够用于处理地层。将这些设备和/或结构布置在隧道中同样可减少用于处理地层的能量源成本，减少来自处理过程的排出物，便于加热系统的安装，和/或与采用地面基设备进行烃回收过程相比减少损失到上覆岩层的热损失。例如这些隧道可以为基本上水平隧道和/或倾斜隧道。
在一些就地处理过程的实施例中，使用循环系统来加热地层。使用用于含烃地层的就地热处理的循环系统可减少用于处理地层的能量成本，减少来自该处理过程的排出物，和/或便于加热系统的安装。在某些实施例中，该循环系统是闭环循环系统。图2示出了使用循环系统加热地层的系统的示意图。该系统可用于加热烃，所述烃位于土地中较深处并且位于相对较大范围的地层中。在一些实施例中，烃可位于地面以下100m、200m、300m或更深。该循环系统还可用于加热并没有深入地中的烃。烃可存在于纵长延伸高达1000m、3000m、5000m或更多米的地层中。该循环系统的加热器可相对于相邻的加热器布置，以使得循环系统的加热器之间的热叠加允许地层的温度至少升高到地层中的含水地层流体的沸点以上。
在一些实施例中，加热器200通过钻出第一井眼然后钻出与第一个井眼相连的第二井眼而形成于地层中。管道可布置在u形井眼中，以形成u形加热器200。加热器200通过管道连接到传热流体循环系统202。在一些实施例中，加热器以三角形图案布置。在一些实施例中，使用了其它规则的或不规则的图案。生产井和/或注入井也可位于地层中。生产井和/或注入井可具有与加热器200的加热部分类似的、的基本水平部段，或者生产井和/或注入井可其它方式定向(例如，这些井可以是竖直定向的井、或者包括一个或多个倾斜部分的井)。
如图2所示，传热流体循环系统202可包括供热装置204、第一热交换器206、第二热交换器208和流体推进器210。供热装置204将传热流体加热到高温。供热装置204可以是炉子、太阳能收集器、化学反应器、核反应堆、燃料室和/或其它能够向传热流体供给热的高温源。如果传热流体是气体，则流体推进器210可以是压缩机。如果传热流体是液体，流体推进器210可以是泵。
在离开地层212之后，传热流体经过第一热交换器206和第二热交换器208到达流体推进器210。第一热交换器206在离开地层212的传热流体与离开流体推进器210的传热流体之间的传热，以升高进入供热装置204的传热流体的温度，以及降低离开地层212的流体的温度。第二热交换器208进一步降低了传热流体的温度。在一些实施例中，第二传热流体208包括用于传热流体的储存罐或者是用于传热流体的储存罐。
传热流体从第二热交换器208流到流体推进器210。流体推进器210可位于供热装置204之前，以使得流体推进器不必在高温下工作。
在一个实施例中，传热流体是二氧化碳。供热装置204是将传热流体加热到从约700℃到约920℃、从约770℃到约870℃、或者从约800℃到约850℃范围内的温度的炉子。在一个实施例中，供热装置204将传热流体加热到约820℃的温度。传热流体从供热装置204流到加热器200。热从加热器200传热到邻近加热器的地层212。离开地层212的传热流体的温度可处于从约350℃到约580℃范围内的温度、从约400℃到约530℃范围内的温度、或者从约450℃到约500℃范围内的温度。在一个实施例中，离开地层212的传热流体的温度是约480℃。用于形成传热流体循环系统202的管道的冶金性可被改变，以显著地降低管道的成本。可从供热装置204到温度足够低的位置处使用高温钢，以使得可从该温度足够低的位置到第一热交换器206使用较为廉价的钢。若干不同等级的钢可用于形成传热流体循环系统202的管道。
在一些实施例中，晒盐(例如包含60wt％(重量百分比)的NaNO3和40wt％KNO3)用作循环流体系统中的传热流体。晒盐可具有约230℃的熔点和约565℃的工作温度上限。在一些实施例中，LiNO3(例如，在约10％重量百分比与约30％重量百分比之间的LiNO3)可添加到晒盐中，以生产具有较宽工作温度范围和较低熔点的第三系盐混合物，只是第三系盐混合物与晒盐相比最大工作温度稍微下降。第三系盐混合物的较低熔点可降低预热要求并且允许使用加压水和/或加压盐水作为用于预热循环系统的管道的传热流体。由在550℃时第三系盐混合物所引起的加热器的金属腐蚀率与由在565℃时晒盐所引起的加热器的金属腐蚀率相当。表1示出了晒盐和第三系盐混合物的熔点和工作温度上限。第三系盐混合物的含水溶液可在移出水时在没有凝固的情况下转变成熔盐，从而允许提供熔盐和/或将熔盐以水溶液形式进行存储。
表1
供热装置204可以是将传热流体加热到约560℃温度的炉子。传热流体的返回温度可以是从约350℃到约450℃。来自传热流体循环系统202的管道可隔热和/或被热追踪，以便于启动和确保流体流动。
在一些实施例中，可使用竖直井、倾斜井或L形井加热器井眼来代替u形井眼(例如在第一位置具有入口而在第二位置具有出口的井眼)。图3示出了L形加热器200。加热器200可联接至传热流体循环系统202，并且可包括入口导管214和出口导管216。传热流体循环系统202可将传热流体供给到多个加热器。来自传热流体循环系统202的传热流体可沿入口导管214向下流并且沿出口导管216向上流回。入口导管214和出口导管216可贯穿上覆岩层218是隔热的。在一些实施例中，入口导管214贯穿上覆岩层218和含烃层220是隔热的，以在使传热流体流入和流出期间抑制不期望的传热。
在一些实施例中，邻近上覆岩层218的井眼222部分比邻近含烃层220的井眼部分更大。使较大开口邻近上覆岩层可允许容纳用于使入口导管214和/或出口导管216隔热的隔热体。从回流中损失到上覆岩层的一些热损失可能没有明显地影响效率，在传热流体是熔盐或者需要加热以保留液体的另一流体时尤其如此。如果传热流体循环结束，邻近加热器200的受热的上覆岩层可将传热流体保持为液体相当长时间。为上覆岩层218留有一些传热余量可消除对出口导管216与上覆岩层之间的昂贵隔热系统的需求。在一些实施例中，绝缘水泥用于上覆岩层218与出口导管216之间。
对于竖直、倾斜或L形加热器，井眼与容纳未通电加热器(例如，已安装但未使用的加热器)所需钻的深度相比可能要钻得更深。在通电之后，加热器的热膨胀可导致加热器的各部分移动到设计用于调节加热器的热膨胀的井眼额外长度。对于L形加热器，井眼中剩余的钻井流体和/或地层流体可随着加热器在预热期间和/或用传热流体加热期间膨胀而促使加热器更深入地运动到井眼中。
对于竖直或倾斜的井眼，井眼与容纳未通电加热器所需钻的深度相比可能要钻得更深。当加热器用传热流体被预热和/或加热时，加热器可延伸到井眼的额外深度。在一些实施例中，膨胀套筒可附连在加热器的末端处，以确保在不稳定钻孔情况下用于热膨胀的可用空间。
在某些实施例中，循环系统使用流体来加热地层。与电热加热器或气体加热器相比，由于用于加热液态传热流体的供热装置的高能量效率，液态传热流体的使用可使得系统的总能量效率高。如果炉子用于加热液态传热流体，由于炉子的效率，该过程的二氧化碳覆盖区(footprint)与电热加热器或使用位于井眼中的气体燃烧器相比可减少。如果核动力用于加热液态传热流体，该过程的二氧化碳覆盖区可显著减小或者甚至消除。用于加热系统的地面设备可以简单的布局由通常可用的工业设备形成。具有简单布局的通常可用的设备可增加系统的总体可靠性。
在某些实施例中，液态传热流体是熔盐或其它如果温度低于选定温度则具有凝固可能性的液体。可能需要第二加热系统以确保传热流体保持为液体形式，并且确保传热流体处于允许传热流体从循环系统流经加热器的温度。在某些实施例中，该第二加热系统将加热器和/或传热流体加热到足以熔化传热流体并确保传热流体的流动性的温度，而不是加热到更高温度。可在流体循环系统的启动和/或重新启动期间很短的时间段内仅仅需要第二加热系统。在一些实施例中，第二加热装置可从加热器移除。在一些实施例中，第二加热装置不具有与加热器的使用寿命相当的预期使用寿命。
在某些实施例中，熔盐用作传热流体。隔热的回流储存罐接收从地层返回的回流熔盐。回流储存罐中的温度例如可在约350℃附近。泵可使熔盐从回流储存罐运动到炉子中。每个泵可需要移动4kg/s到30kg/s之间的熔盐。每个炉子可向熔盐供给热。熔盐从炉子离开的温度可以为约550℃。熔盐可从炉子通过管道流到隔热的供给储存罐。例如，每个供给储存罐可将熔盐供给到50个或更多个进入地层中的管道系统。熔盐流经地层并且流到回流储存罐。在某些实施例中，炉子具有90％或更高的效率。在某些实施例中，损失到上覆岩层中的热损失为8％或更少。
在一些实施例中，用于循环系统的加热器包括沿着加热器长度的隔热体，其包括用于加热处理区的加热器部分。隔热体可便于将加热器插入地层中。邻近用于加热处理区的加热器部分的隔热体可足以在预热期间提供隔热，但在由传热流体的稳态循环所产生的温度下可能分解(decompose)。在一些实施例中，隔热体层改变了加热器的辐射率，以抑制从加热器的辐射传热。在隔热体分解之后，加热器的辐射率可促进向处理区辐射传热。隔热体可缩短将加热器和/或加热器中的传热流体的温度升高到足以确保熔化传热流体和确保传热流体流动性的温度所需要的时间。在一些实施例中，邻近将加热处理区的加热器部分的隔热体可包括聚合物涂层。在某些实施例中，邻近上覆岩层的加热器部分的隔热体不同于邻近用于加热处理区的加热器部分的隔热体。邻近上覆岩层的加热器的隔热体可具有与加热器的使用寿命相等或更长的预期使用寿命。
在一些实施例中，在加热器放置之后或放置期间，可降解的隔热材料(例如聚合体泡沫)可被引入井眼中。可降解的隔热体可在预热期间提供邻近用于加热处理区的加热器部分的隔热。用于加热处理区的液态传热流体可将加热器的温度升得足够高以降解和除去隔热体层。
在使用熔盐或另一液体作为传热流体的循环系统的一些实施例中，加热器可以是地层中的单个导管。导管可被预热到足以确保传热流体的流动性的温度。在一些实施例中，第二传热流体循环通过导管以预热导管和/或邻近该导管的地层。在导管或邻近该导管的地层的温度足够热之后，可从导管中冲走第二流体，传热流体可循环通过管子。
在一些实施例中，将用作传热流体的由盐组合物构成的水溶液(例如Li:Na:K:NO3)用于预热导管。第二传热流体的温度可低于或等于井口的地下出口的温度。
在一些实施例中，第二传热流体(例如水)可被加热到0℃到约95℃范围内的温度或者高达第二传热流体沸点的温度。在处于循环系统的储存罐中时，盐组合物可添加到第二传热流体中。盐的组合物和/或系统的压力可被调节，以抑制在温度增加时水溶液的沸腾。当导管被预热到足以确保熔盐流动性的温度时，剩余的水可从水溶液中除去，而仅仅剩下熔盐。当盐溶液处于循环系统的储存罐中时，水通过蒸发而被除去。在一些实施例中，熔盐溶液的温度可被升高到100℃以上。当导管被预热到足以确保熔盐的流动性的温度时，剩余的第二传热流体(例如，水)中的大部分或者全部从盐溶液中移除，而仅仅留下熔盐。在一些实施例中，熔盐溶液的温度在蒸发过程期间在从100℃到250℃的范围内。
在就地热处理过程完成时，熔盐可被冷却并且水被添加到盐中以形成另一水溶液。该水溶液可被传送到另一处理区并且继续进行该过程。将第三系熔盐用作水溶液便于传输溶液并且允许地层的一个以上部段用相同的盐进行处理。
在一些使用熔盐或其它液体作为传热流体的循环系统的实施例中，加热器可具有导管中导管结构。用于加热地层的液态传热流体可流经穿过加热器的第一通道。第二传热流体可流经穿过导管中导管加热器的第二通道，以用于预热液态传热流体和/或用于确保液态传热流体的流动。在加热器被升高到足以确保传热流体连续流经加热器的温度之后，在用于第二传热流体的通道抽真空以抑制从第一通道到第二通道的传热。在一些实施例中，用于第二传热流体的通道用隔热材料填充和/或通过其它方式被阻塞。导管中导管加热器的导管中的通道可包括内部导管和内部导管与外部导管之间的环形区域。在一些实施例中，一个或多个流动转换器用于改变导管中导管加热器中从内部导管到环形区域的流动和/或反之亦然。
图4示出了用于邻近处理区300的传热循环加热系统的导管中导管加热器200的一个实施例的剖视图。加热器200可定位于井眼222中。加热器200可包括外部导管302和内部导管304。在加热器200的正常工作期间，液态传热流体可流经外部导管302与内部导管304之间的环形区域306。在正常工作期间，可不需要流体流经内部导管302的流动。
在预热期间和/或为了确保流动，第二传热流体可流经内部导管304。第二流体可以是，但并不限于，空气、二氧化碳、废气和/或天然的或合成的油(例如，DowTherm A、Syltherm或Therminol 59)、室温熔盐(例如，NaCl2-SrCl2、VCl4、SnCl4或TiCl4)、高压液态水、蒸汽、或室温熔融的金属合金(例如，K-Na共熔物或Ga-In-Sn共熔物)。在一些实施例中，在用于加热地层的传热流体被引入环形区域之前，外部导管302被流经环形区域308的第二传热流体(例如，二氧化碳或废气)加热。如果使用废气或其它高温流体，则另一传热流体(例如，水或蒸汽)可流经加热器，以将温度降低到液态传热流体的工作温度上限以下。在液态传热流体被引入加热器时，第二传热流体可从环形区域移出。内部导管304中的第二传热流体可以是与用于在预热期间预热外部导管302的第二流体相同的流体或者不同的流体。使用两种不同的第二传热流体可帮助识别加热器200中的整体性问题。在开始使用熔盐之前可识别任何整体性问题。
在一些实施例中，在预热期间流经环形区域306的第二传热流体是在正常工作期间所使用的盐的含水混合物。盐的浓度可周期性地增加以升高温度，同时将温度保持在含水混合物的沸腾温度以下。含水混合物可用于将外部导管302的温度升高到足以允许熔盐在环形区域306中流动的温度。当到达该温度时，含水混合物中的剩余水可从混合物中蒸发掉，从而留下熔盐。熔盐可用于加热处理区300。
在一些实施例中，内部导管304可由相对廉价的材料(诸如碳钢)制成。在一些实施例中，内部导管304可由经受得住热处理过程的初始早期阶段的材料制成，外部导管302可由耐熔盐和地层流体腐蚀的材料(例如，P91钢)制成。
对于液态传热流体的给定质量流率，使用在外部导管302与内部导管304之间的环形区域306中流动的液态传热流体加热处理区相对于使液态传热流体流经单个导管具有某些优点。在首次使用液态传热流体时和/或在循环停止之后需要重新开始流动时，使第二传热流体流经内部导管304可预热加热器200和确保流动。外部导管302的大外表面积向地层提供用于传热的大表面积，以此同时由于存在内部导管304，循环系统所需的液态传热流体的量减小。由于对于相同质量流率来说液态传热流体的速度增大，循环的液态传热流体可向处理区提供更好的动力注入率分布。还可提高加热器的可靠性。
在一些实施例中，传热流体(熔盐)可变稠，流经外部导管302和/或内部导管304的传热流体的流动变慢和/或被削弱。选择性地加热内部导管304的各部分可向加热器200的各部分提供足够的热，以增大流经加热器的传热流体的流动。加热器200的各部分可包括铁磁性材料(例如绝缘导体)，以允许电流沿着加热器的选定部分经过。对内部导管304电阻加热将足够的热传递给外部导管302和/或内部导管304中变稠的传热流体，以降低传热流体的粘性，从而与在加热熔盐之前通过管道的流动相比获得了增大的流动。使用随时间变化的电流允许电流沿着内部导管通过，而不经过传热流体。
图5示出了用于加热加热器200的各部分以使加热器中变稠的或不流动的传热流体(例如熔盐)重新开始流动的示意图。在某些实施例中，内部导管304和/或外部导管302的各部分包括被隔热体围绕的铁磁性材料。因而，内部导管304和/或外部导管302的这些部分可以是绝缘导体308。绝缘导体308可作为限温加热器或集肤效应加热器。由于绝缘导体308的集肤效应，提供给绝缘导体的电流保持限制在内部导管304和/或外部导管302内，并且不会流经位于导管中的传热流体。
在某些实施例中，绝缘导体308沿着内部导管304的选定长度(例如，内部导管的整个长度或仅内部导管的上覆岩层部分)定位。将电施加给内部导管304以在绝缘导体308中产生热。所产生的热可沿着内部导管的选定长度加热变稠的或不流动的传热流体。所产生的热可加热内部导管内部的传热流体和内部导管与外部导管302之间的环形空间内的传热流体。在某些实施例中，内部导管304仅包括定位于内部导管的上覆岩层部分中的绝缘导体308。这些绝缘导体在内部导管304的上覆岩层部分中选择性地产生热。选择性地加热内部导管304的上覆岩层部分可将热传递给内部导管的上覆岩层部分中的变稠的传热流体并且重新开始流动。这种选择性的加热可通过将热集中在最可能遇到传热流体的变稠或不流动的区域而延长加热器的寿命以及使电加热成本最小化。
在某些实施例中，绝缘导体308沿着外部导管302的选定长度(例如，外部导管的上覆岩层部分)定位。将电施加给外部导管302以在绝缘导体308中产生热。所产生的热可选择性地加热内部导管304与外部导管302之间的环形空间的上覆岩层部分。可从外部导管302传递足够的热以降低变稠的传热流体的粘性，从而允许熔盐在环形空间中的流动未削弱。
在某些实施例中，具有导管中导管加热器构造允许使用流动转换器，该流动转换器将传热流体在加热器中的流动从在流动邻近处理区时的流经外部导管与内部导管之间的环形区域改变成在流动邻近上覆岩层时流经内部导管。图6示出了用于与流体循环系统202、202’一起使用以加热处理区300的导管中导管加热器200的示意图。在某些实施例中，加热器200包括外部导管302、内部导管304和流动转换器310。流体循环系统202、202’向井口311提供已加热的液态传热流体。液态传热流体的流动方向由箭头321表示。
来自流体循环系统202的传热流体流经井口311进入内部导管304中。传热流体流经流动转换器310，该流动转换器将流动从内部导管304改变到外部导管302与内部导管之间的环形区域。传热流体于是流经处理区300中的加热器200。来自传热流体的传热向处理区300提供热。传热流体于是流经第二流动转换器310’，该第二流动转换器将流动从环形区域改变成返回内部导管304。传热流体通过第二井口311’从地层中移出并且被提供给流体循环系统202’。来自流体循环系统202’的已加热的传热流体流经加热器200’返回流体循环系统202。
在流体邻近处理区300时，使用流动转换器310使流体流经环形区域促进了向处理区的增大的传热，这部分地是由于外部导管302的大传热面积。在邻近上覆岩层218时，使用流动转换器310使流体流经内部导管可减小损失到上覆岩层的热损失。另外地，加热器200在上覆岩层218附近可隔热以便减小损失到地层的热损失。
图7示出了邻近上覆岩层218的导管中导管加热器200的一个实施例的剖视图。隔热体314可定位于外部导管302与内部导管304之间。液态传热流体可流经内部导管304的中心。隔热体314可以是高孔隙率的隔热体层，其抑制高温(例如，500℃以上的温度)下的辐射并且允许在预热期间第二传热流体的流动和/或确保加热阶段的流动。在正常工作期间，可停止或抑制在上覆岩层218附近流经外部导管302与内部导管304之间的环形区域的流体流动。
隔热套315可围绕外部导管302定位。u形加热器的每一侧上的隔热套315可在系统未被加热时在很长长度上牢固地联接至外部导管302，以使得u形井眼的每一侧上的隔热套能够支承加热器的重量。隔热套315可包括外部构件，该外部构件是允许加热器200被提升以调节加热器的热膨胀的结构构件。套管317可环绕隔热套315。绝缘水泥319可将套管317联接至上覆岩层218。绝缘水泥319可以是减小传导热损失的低导热性水泥。例如，绝缘水泥319可以是蛭石/水泥聚合物。不反应的气体可被引入隔热套315与套管317之间的间隙321中，以抑制地层流体在井眼中上升和/或提供隔热气体覆层。
图8示出了循环系统202的一个实施例的示意图，所述循环系统向地层中的导管中导管加热器(例如，图6所示的加热器)供应液态传热流体。循环系统202可包括供热装置204、压缩机316、热交换器318、排气系统320、液体储存罐322、流体推进器210(例如，泵)、供给歧管324、回流歧管326和第二传热流体循环系统328。在某些实施例中，供热装置204是炉子。用于供热装置204的燃料可通过燃料管线330供给。控制阀332可基于由温度监测器334测量的热传热流体的温度来调控供给到供热装置204的燃料量。
用于供热装置204的氧化剂可通过氧化剂管线336供给。来自供热装置204的排出气可经过热交换器318到达排气系统320。来自压缩机316的氧化剂可经过热交换器318以便被来自供热装置204的排出气加热。
在一些实施例中，阀338在预热期间和/或启动对加热器的流体循环期间可被打开，以便为第二传热流体循环系统328提供加热流体。在一些实施例中，排出气经由第二传热流体循环系统328循环通过加热器。在一些实施例中，排出气经过第二传热流体循环系统328的一个或多个热交换器，以加热循环通过加热器的流体。
在预热期间，第二传热流体循环系统328可将第二传热流体供给到加热器的内部导管和/或供给到内部导管与外部导管之间的环形区域。管线340可将第二传热流体提供到将流体供给到加热器的内部导管的供给歧管324部分。管线342可将第二传热流体提供到将流体供给到加热器的内部导管与外部导管之间的环形区域的供给歧管324部分。管线344可从将流体从加热器的内部导管返回的回流歧管326部分使第二传热流体回流。管线346可从将流体从加热器的环形区域返回的回流歧管326部分使第二传热流体回流。第二传热流体循环系统328的阀348可允许或停止第二传热流体流入或流出供给歧管324和/或回流歧管326。在预热期间，所有阀348可以是开放的。在加热的确保流动阶段期间，用于管线340和管线344的阀348可以是关闭的，而用于管线342和管线346的阀348可以是开放的。来自供热装置204的液态传热流体可提供到在加热的确保流动阶段期间将流体供给到加热器的内部导管的供给歧管324部分。液态传热流体可从使流体从加热器的内部导管回流的回流歧管326部分回流到液体储存罐322。在正常工作期间，所有阀348可以是关闭的。
在一些实施例中，第二传热流体循环系统328是可动的系统。一旦建立传热流体流经加热器的正常流动，可使可动的第二传热流体循环系统328运动并且附连至尚未启动的另一循环系统。
在正常工作期间，液体储存罐322可从返回歧管326接收传热流体。液体储存罐322可隔热和被热跟踪(heat traced)。热跟踪可包括使蒸汽循环通过液体储存罐322中的旋管(coils)的蒸汽循环系统350。经过旋管的蒸汽将液体储存罐322中的传热流体保持在期望的温度下或者在期望的温度范围内。
流体推进器210可以使液态传热流体从液体储存罐322运动到供热装置204。在一些实施例中，流体推进器210是位于液体储存罐322中的潜水泵。使流体运动器210处于储存罐中可保持泵很好地处于泵的操作温度极限内的温度下。再者，传热流体可用作泵的润滑剂。一个或多个冗余的泵系统可放置于液体储存罐322中。如果第一泵系统关闭或需要维修的话，则可使用冗余的泵系统。
在供热装置204的启动期间，阀352可将液态传热流体引导至液体储存罐。在完成地层中加热器的预热之后，阀352可重新配置为将液态传热流体引导至将液态传热流体供给到已预热的加热器的内部导管的供给歧管324部分。从已预热的回流导管的内部导管回流的液态传热流体可经过接收经过地层的传热流体并将传热流体引导至液体储存罐322中的返回歧管326部分。
为了开始使用流体循环系统202，可使用蒸汽循环系统350来加热液体储存罐322。传热流体可被添加到液体储存罐322中。传热流体可作为在液体储存罐322中熔化的固体颗粒被添加，或者液体传热流体可被添加到液体储存罐中。供热装置204可被启动，并且流体推进器210可用来将传热流体从液体储存罐322循环到供热装置并且返回。第二传热流体循环系统328可用来加热地层中的加热器，这些加热器与供给歧管324和返回歧管326联接。可停止将第二传热流体供给到对加热器的内部导管进行供料的供给歧管324部分。同样，可停止第二传热流体来自从加热器的内部导管接收传热流体的回流歧管部分的回流。来自供热装置204的传热流体于是被引导至加热器的内部导管。
传热流体可流经加热器的内部导管到达流动转换器，所述流动转换器将流体流动从内部导管转变成流向内部导管与外部导管之间的环形区域。然后，传热流体可经过流动转换器，这些流动转换器将流动改变成返回内部导管。与加热器联接的阀可允许传热流体流入各加热器，以便按顺序启动各加热器，而不是使流体循环系统将传热流体一次性供给到全部加热器。
返回歧管326接收经过地层中加热器的传热流体，这些加热器从第二流体循环系统被供给传热流体。返回歧管326中的传热流体可被引导返回到液体储存罐322中。
在最初加热期间，第二传热流体循环系统328可继续将第二传热流体循环通过不接收由供热装置204供给的传热流体的加热器部分。在一些实施例中，第二传热流体循环系统328沿与由供热装置204供给的传热流体的流动相同的方向引导第二传热流体。在一些实施例中，第二传热流体循环系统328沿与由供热装置204供给的传热流体流动相反的方向引导第二传热流体。第二传热流体可确保由供热装置204供给的传热流体的持续流动。当由于由供热装置204供给的传热流体的传热而使得离开地层的第二传热流体比供给地层的第二传热流体更热时，可停止第二传热流体的流动。在一些实施例中，在一段选定时间段之后，在满足其它条件时，可停止第二传热流体的流动。
