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.
  • 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 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 installation for surface, said cable being provided with a pluggable connector in a delayed manner, movable along the tubular column by the action of a stream of fluid.
  • the device is characterized in that it comprises means for intermittently drifting outside the intervention area, at least part of the fluid current established for the propulsion of said connector, the latter being adapted during its movement to open or close said exhaust means.
  • the bypass means comprise for example at least one valve upstream of the measuring means which communicates the interior of the column and the annular space between it and the well.
  • this valve is a sliding valve.
  • the device may include retractable retaining means for intermittently securing in translation the bypass means.
  • the bypass means comprise 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 shirt towards its advanced position and means for intermittently locking the load part with respect to said jacket.
  • the device may also include means for intermittently locking said 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 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 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, said 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, the production of which must be activated by a pumping assembly 6 which may include a volumetric pump of the Moineau 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 to measure 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 electrically supplied 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 is pluggable in a deferred manner, surmounted by a load bar 13.
  • a connector of this type is used for example in the device described in French patent 2,501,777.
  • the connector 12 is introduced inside the column by the opening in the wall of a connector 14 of the side-entry sub type, interposed on the drill string which constitutes it.
  • By pumping fluid one can move such a connector 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 open 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 locking 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 traction 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 29 is blocked in the groove 28.
  • each element 31 engages in the groove 29.
  • the measuring assembly can be relatively distant from the pumping assembly.
  • the connection operations are likewise simplified by connecting the two assemblies by a cable 33 provided with a connector 34 analogous to the connector and by adapting, in the vicinity of the measurement assembly 8, the described device of sliding valve 35 analogous 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 37 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.
