Definitions
- the invention relates to a device by tubing in an oil well or a gas well, hereinafter only referred to as a well.
- tubing In the production of oil and gas, oil/gas is lead to the surface through so-called tubing in a well.
- tubing At the surface, at the upper end of the tubing, comprehensive valving and safety equipment are arranged thereto.
- the tubing has a seal arranged thereto, the so-called packer, which is arranged to seal between the tubing and the wall of the well, which is normally lined with a steel tube also called casing, so that oil or gas cannot enter the an- nulus outside the tubing.
- the casing is perforated, so that oil or gas may flow into the well, further up into the tubing and to the surface.
- a filter for example a gravel pack, which is to prevent sand from the reservoir from being carried by the gas or oil flow.
- the lower end of the casing which is in the productive zone of the well i.e. the part of the casing located between the packer and the bottom of the well, is of particular interest and calls for attention for several reasons. It is desirable to be able to decide which part of the reservoir to produce from. This is decided partly by positioning the perforations in the right area of the casing. It is topical to carry out perforation in several turns to exploit the reservoir, zone by zone, in the course of time.
- Sensor signals are transferred to the surface through lines running in the annulus outside the tubing.
- the sensors are installed at the same time as the tubing, and the lines are secured to the exterior of the tubing.
- Possible actuators for downhole valves are ener- gised by lines from the surface and are controlled from the surface, either by controlling the energy supply or through particular control signals. Both electric and hydraulic lines may be of interest. Deposits occur in the tubing, particularly in the lower part of the tubing. In connection with well maintenance it is of current interest to perform mechanical cleaning inside the tubing. Sensors, actuators, chokes and other equipment must either be arranged to bear and give room for such cleaning, or the equipment must be removed before cleaning is started.
- the packer is of great importance in terms of safety, and quite naturally there are strict requirements to the packer itself and to the setting of it.
- the packer may not be removed, unless other satisfactory security is provided.
- a superior object of the invention is, therefore, to simplify the maintenance and use of equipment in an area between the packer and the well bottom. In particular it is an object to simplify installation and maintenance of equipment which is to be connected to lines in said area.
- the well is provided with a tubing which in a known manner has a packer arranged thereto.
- a telescopic extension of the tubing is arranged to permit connection to a holder inside the tubing, so that the telescopic part projects from the lower end of the tubing.
- the telescopic part may be re- leased from the holder and be extracted from the well for maintenance.
- Sensors, chokes, valves and actuators and other equipment may be mounted in the telescopic part before the latter is run into the well.
- lines belonging to said sensors and actuators are terminated in a part of a coupling which is arranged to co-operate with a complementary connection part in the tubing.
- the lines may with advantage be passed in particular channels in the body material of the telescopic part.
- Said complementary connection part is arranged to the tubing further from the well bottom than where the packer is.
- the complementary connection part is connected to lines which are passed, in a known manner, in the annulus outside the tubing to equipment on the sur- face.
- reference numeral 1 defines a well, in which a tubing 2 is arranged in a manner known in itself.
- the well 1 is shown having a casing 3 which is fixed through cementation and is perforated in its lower part.
- a packer 4 is in an ordinary manner set be- tween the tubing 2 and the casing 3.
- a holder 5 carrying a telescopic part 6 which projects from the lower part of the tubing 2.
- the telescopic part 6 is stepped and rests on a shoulder 7 of the holder 5.
- the telescopic part 6 is provided, in a manner known in itself, with grippers 8 which are arranged to allow radial displacement thereof to engage an annular groove 9 in the holder 5 and thereby lock the telescopic part to the holder 5.
- the grippers 8 are arranged so that they can be triggered to release the telescopic part 6 from the holder 5 by means of a tool 10, which is arranged to be releasably connected to the upper end of the telescopic part 6.
- the tool 10 is provided with a set of external locking pins 11 which are arranged to engage an internal locking groove at the upper end of the telescopic part 6.
- the grippers 8 and the locking pins 11 with complementary recesses 9, 12 may, with advantage, be made in accordance with known principles, which are used for grippers and locking pins of known equipment and tools.
- a first part 13 of an inductive coupling which is arranged to be able to cooperate with a second part 14 of said inductive coupling.
- the first part 13 of the inductive coupling 13, 14 has a first set of electric conductors 15 arranged thereto, for transferring energy and electric signals between the first part 13 of the inductive coupling 13 , 14 and not shown equipment on the surface.
- the second part 14 of the inductive coupling 13, 14 is electrically connected to a sensor 17 and an actuator 18, which has an adjustable choke valve 19 in the telescopic part 6, by means of a second set of electric conductors 16. Electric signals are transferred between the sensor 17 and the actuator 18 via the electric conductors 15, 16 and the inductive coupling 13, 14.
- Conductive, electric couplings may also be provided, for example through plugable electric connectors in the bearing surface by the shoulder 7.
- a person skilled in the art may easily arrange hydraulic connections for the transfer of hydraulic energy and hydraulic signals between the holder 5 and the telescopic part 6.
- the first set of electric and/or hydraulic lines 15 may in a known manner be passed in the annulus outside the tubing 2 and above the packer 4.
- the second set of lines 16 may, with advantage, be passed in not shown channels in the body material of the telescopic part 6.
- Seals 20, 21 define a zone in an annulus 22 below the end of the tubing 2 and outside the telescopic part 6, which is shown to be sealed at its lower end.
- a set of ports 23 in the telescopic part 6 is arranged to direct oil or gas from the defined zone of the annulus 22 into the telescopic part 6 below the choke valve 19, as the well 1 is provided with perforations 24. Production of oil/gas may be controlled from the surface by remote control of the choke 19 based on signals from the sen- sor 17. As required, more sensors, more valves, more zone-defining seals and more sets of ports may be provided in the telescopic part 6.
- the tool 10 is inserted into the well 1 and connected to the upper end of the telescopic part 6, so that the locking pins 11 engage the locking recess 12.
- the grippers 8 are passed out of the groove 9 of the holder 5, and the telescopic part 6 may be pulled up and out of the well 1, hanging from the tool 10.
- the telescopic part 6 is ready for use, it is lowered into the well 1, hanging from the tool 10, until the telescopic part 6 lands on the shoulder 7 of the holder 5.
- the locking pins 11 are released so that the tool 10 may be pulled up and out from the telescopic part 6.
- the grippers 8 are activated to engage the groove 9 , so that the telescopic part 6 is locked to the holder 5.
