Definitions
- the present invention relates to equipment for a drill string such as a drill string comprising a side window connection for the passage of a cable from the inside to the outside of the rods, with hydraulic sealing around the cable.
- a side window fitting is, for example, used in the technique described in French patent 2 501777 (EN 81/05 271) and its first two additions EN 82/03 317 and EN 84/08 369.
- a logging probe or an intervention tool is initially fixed to the lower part of a drill string which is lowered into the well at as it was created.
- An electrical cable fitted with a weighted connector (the connector is surmounted by a load bar) is then lowered inside the rods (by gravity and by pumping) which is connected to a complementary connector fixed to the top of the probe (or the tool).
- a side window fitting passes the cable from the interior to the exterior of the rods.
- the measurement recording (or intervention in the well) is carried out by moving the entire drill string from the surface.
- loosening operations or interventions are, for example, the introduction into the rod, from the surface, of specialized tools to be lowered by means of a cable to the area (which is generally located under the inlet fitting lateral) which includes the stems trapped by the formation.
- These specialized tools can, for example, be an explosive which allows the unscrewing of the stuck rod.
- This problem is solved according to the invention with equipment for a drill string comprising a lateral window fitting adapted to be incorporated into the drill string, this window allowing the passage of a cable, characterized in that it comprises a sleeve which can slide inside said connection between a high position situated above said window and a low position in which this sleeve closes said window, said sleeve being provided with retaining members in each of said positions and comprising means for cutting the cable when the said jacket passes from its high position to its low position.
- the equipment according to the invention comprises a plug for closing said shirt at its upper end, this plug allowing said shirt to be moved from its high position to its low position under the effect of hydraulic pressure exerted from the surface in the drill pipe and comprising at its top a removal and recovery device.
- US-A-4512411 teaches to cut a cable passing right through a cylinder. According to this prior patent, the cable is cut by shearing it by a radial movement of jaws.
- US-A-4,160,478 mainly provides for the perforation of a tube being in a casing and traversing the latter right through.
- the cutting member has a rotational movement about an axis. During this movement, it enters the tube causing a partial tear thereof.
- the reference 1 designates the connection with side window screwed between two elements 1a and 1b of the drill string.
- This connector has a side window 2 allowing the passage of an electrical cable 3 from the outside to the inside of the rods along a ramp 4.
- This cable is, for example, of a type used for logs or interventions carried out according to the technique described in French patent 2,501,777 and its aforementioned additions.
- a member 5 seals around the cable 3 where it passes from the inside of the connector 1, this member being immobilized by a wedging finger 5a. Outside the connector 1, the cable 3 passes successively over a guide roller 6 and through an anchoring member 7 where it is mechanically blocked by a system of any suitable type, comprising for example a shearable pin, allowing the release of the cable 3 under the action of a sufficient tensile force exerted on this cable from the surface.
- organs 5 and 7 are within the reach of specialists and will not be described here in more detail.
- a jacket 8 is slidably mounted in the axial bore 9 of the connector 1, a seal being formed between this jacket 8 and the bore 9, for example by an O-ring 10.
- Figure 1 shows the sliding jacket 8 in its upper position revealing the window 2, so as to allow the passage of the cable 3.
- a shear pin 11 retains the jacket 8 in this position.
- FIG. 2 illustrates the second position of the jacket 8 where this jacket closes the side window 2.
- the wall of the sliding sleeve 8 is tapered at its lower part so as to constitute a cutting member with a bevel section 12, suitable for cutting the cable 3 in its low position, this member then coming into contact with a ring 13 constituting a sleeve retaining ring shoulder 8.
- the reference 14 designates an annular sealing member placed above the ring 13.
- a safety pin 15, retractable against the action of a spring 16, is applied against the outer wall of the jacket 8 in the high position of FIG. 1, while in the position of FIG. 2 this pin comes s 'engage in a suitable housing 17 formed in the head of the sliding sleeve 8.
- a plug 18 can be adapted to the upper part of the sliding jacket 8 to close it, this plug being provided with a removal and recovery head 19 allowing the plug 18 to be gripped by an appropriate tool which may be of a known type .
- This removal and recovery tool for the sealing plug 18 will be placed at the lower end of a cable or an operating rod (not shown).
- the plug 18 makes it possible to move the jacket 8 from its high position (Fig. 1) to its low position (Fig. 2) under the effect of hydraulic pressure exerted from the surface in the drill pipe.
- the implementation of this equipment is indicated below.
- the jacket 8 is held in the low position by the engagement of the pin 15 in the housing 17.
- the seals 10 and 14 located respectively at the upper part and at the lower part of the jacket 8 then ensure a good seal between the inside and the outside of the drill string.
- This loosening can also be carried out by introducing from the surface from the inside of the rods, tools of types well known to drillers, allowing the rods to be unscrewed.
