Definitions

  • the present invention relates to an improved device for carrying out interventions in deviated non-eruptive production wells, such as activation of production and measurements on the effluents produced.
  • a device for intervention in deviated wells carrying out production activation and measurements on the multiphase effluents produced This device is installed at the lower end of a production column.
  • the connection to a command and control station on the surface is carried out by means of a multi-function cable comprising power supply lines and lines for transmitting measurement signals.
  • the cable is terminated by a delayed plug connector.
  • the connector is introduced into the column by a connector with side window and propelled by a current of fluid until its connection on a male plug fixed to the intervention device.
  • the pumping of the connector in a very deviated part of the column or tubing requires injecting a large amount of propellant fluid into the connection area to the device, that is to say the producing area.
  • This fluid brought into the production area distorts the measurements. It may also damage certain instruments such as flow meters which are designed to treat fluids flowing in the opposite direction to the outside of the well.
  • This circulation of fluid is braked or even impossible with certain types of pump. This is the case in particular with volumetric pumps with relatively low flow rate of the Moineau type for example.
  • the improved device according to the invention makes it possible, for all well configurations, to electrically supply an activation and measurement system by means of a cable provided with a plug-in connector in a deferred manner by means of a current of fluid, this device being arranged to avoid the possible drawbacks of prior devices.
  • the improved device makes it possible to carry out interventions, in deviated non-eruptive production wells, such as activation of production and measurements on the effluents produced. It comprises a production column connected to a surface installation comprising at least one connection with an interposed side window, means for closing the annular space between the well and the column, an intervention assembly comprising means for activating the production of the well and the means of measuring at least part of the effluents produced and at least one connecting cable connecting the activation means and / or the measuring means to said installation for surface, said cable being provided with a pluggable connector in a deferred manner, movable along the tubular column by the action of a stream of fluid.
  • the device is characterized in that it comprises at least one bypass valve for drifting on command towards the outside of the production column, at least part of the fluid current established inside this column for the propulsion of said connector, the latter being adapted during its movement to open or close the bypass valve.
  • the bypass valve is placed for example upstream of the measuring means.
  • this valve is a sliding valve, and in this case, the device may include retractable retaining means for securing the valve in translation intermittently.
  • the bypass valve comprises for example at least one jacket which can slide inside the column and in the vicinity of the intervention zone between a withdrawal position where it discovers openings made through the side wall of the column, and an advanced position where it closes said openings, this jacket being provided internally with radial extensions, a load part associated with the connector, provided with bosses adapted to come into abutment against said radial extensions and push said jacket towards its advanced position and means for intermittently locking the load part with respect to this jacket.
  • the device may also include means for intermittently locking the sliding jacket relative to the wall of the column.
  • connection cable is for example a multi-conductor cable comprising power supply lines and lines for transmitting control and measurement signals.
  • the device may for example comprise a second cable also provided with a pluggable connector in a deferred manner, which connects the activation means and the surface installation.
  • the invention also relates to a method for carrying out interventions in deviated non-eruptive production wells, such as activation of production and measurements on the effluents produced comprising the installation of a production column connected to an installation. surface and provided with at least one fitting with an interposed lateral window, means for closing the annular space between the well and the column, an intervention assembly comprising means for activating the production of the well and means for measuring at least part of the effluents produced, and at least one connecting cable connecting the activation means and / or the measuring means to said surface installation, this cable being provided with a connector which is movable along the column by the action of a stream of fluid, the intervention assembly being adapted to be connected in a delayed manner with said plug-in connector.
  • the well 1 shown in Figs 1, 2 is drilled from a surface installation 2 into an oil formation 3. In its lower part crossing an oil-producing area, the well 3 is deviated by an angle more or less pronounced with respect to the vertical. It is equipped with a tube or "liner" 4 with perforations 5 in its part which crosses the production area. It is a non-eruptive well whose production must be activated by a pumping assembly 6 which may include a positive displacement pump of the Sparrow type for example. According to the embodiment of Fig.1, the pumping assembly 6 is arranged in the vicinity of the end of a production column or tubing 7.
  • a measuring assembly 8 can include several different instruments for measuring different parameters indicative of production: plotter-ejector, gamma densimeter, capacitance meter, etc.
  • a sealing member 9 of a known expandable type or with cups, is arranged for example around the column to separate the parts of the well on either side. The effluents from the formation pass through the measuring assembly 8 and through the column 7, they are discharged towards the surface by means of the pumping assembly 6.
  • This comprises a drive motor 10 supplied electrically from the surface installation 2 by a multi-conductor cable 11 comprising supply lines and data transmission lines.
  • the cable 11 is terminated by a connector 12 which can be plugged in deferred manner, surmounted by a load bar 13.
  • a connector of this type is used for example in the device described in FR-A-2.501.777.
  • the connector 12 is introduced inside the column by the opening in the wall of a connector 14 of the side window entry type (side-entry sub), interposed on the drill string which constitutes it.
  • By pumping fluid such a connector can be moved until it is completely plugged into a multi-contact male plug 15 (FIG. 1, 3) fixed on the pumping assembly and connected to the electric motor 10 for driving the pumping assembly 6.
  • a multi-contact male plug 15 FIG. 1, 3
  • the measuring assembly 8 is electrically supplied and can transmit measurement data.
  • the device comprises, in the vicinity of the pumping assembly, a bypass valve 17 adapted, in the open position, to divert the fluid used to propel the connector 12 and its load bar 13 towards the annular space 18 around the column 7.
  • a bypass valve 17 adapted, in the open position, to divert the fluid used to propel the connector 12 and its load bar 13 towards the annular space 18 around the column 7.
  • This valve 17 is a sliding valve for example. It comprises (FIG. 3, 4) a jacket 19 of external section substantially equal to the internal section of the tubular column 7 which can slide from a withdrawal position where it discovers openings 20 in the side wall of the column 7, at its periphery, to an advanced position where it covers these openings. Seals 21 are arranged in the wall of the column on either side of the openings to establish the tightness of the valve 17 in the closed position. On its inner wall, the jacket 19 is provided with radial extensions 22 through which the connector 12 can pass freely.
  • the load bar 13 is provided with external bosses 23 of greater cross-section than that of the radial extensions 22 so as to come into abutment against it in the valve open position (Fig.
  • the device is also arranged so that the withdrawal of the connector disengaging from its insertion position, causes the valve to open.
  • the sleeve 19 is provided with an internal groove 24 and the load bar comprises housings for one or more blocking elements 25.
  • Each element 25 comprises a latch 26 pushed radially by a spring 27 and positioned so as to come to engage in the groove 24 when the load bar is in abutment on the radial extensions 22.
  • the tension of the springs 27 is sufficient for the or each lock 26 to drive the jacket when the load bar is pulled back by a traction exerted on the cable 7. This tension of the springs is limited so that the latches disengage from the groove 24 when the tensile force exerted on the cable is sufficient, which allows the connector to rise.
  • the jacket of the valve is provided externally with grooves 28, 29.
  • Housing is provided in the inner wall of the column on either side of the openings 20, for locking elements 30 , 31 analogous for example to element 26.
  • each element 30 is blocked in the groove 28.
  • each element 31 engages in the groove 29.
  • the measuring assembly can be relatively far from the pumping assembly.
  • the connection operations are likewise simplified by connecting the two assemblies by a cable 11a provided with a connector 34 similar to the connector 12 and by adapting, in the vicinity of the measurement assembly 8, the device described for the sliding valve 35 similar to the valve 19 operated by the translational movements of the load bar 36 associated with the connector 34.
  • the previous device can be completed by placing another sliding valve 17 above the pumping assembly so as to also divert the fluid which is used to move the connector towards its engagement position outside the column.
