Definitions
- the present invention relates to a fishing tool for cable-based retrieval of equipment from a borehole.
- WO-Al 2006/006872 provides an example of wipers for internal removal of drilling mud from the drill string.
- the wiper is made having a mass and a volume that allow it to float on top of the drilling mud during the tripping operation.
- the wiper is bellows-shaped and comprises a weight that is connected to its upper part.
- the wiper is equipped with one or more channels past or through it so as to allow through-flow of the drilling mud.
- a fishing tool for cable-based retrieval of equipment from a borehole characterised in that the tool comprises a seat cone, an inner spring that tensions the seat cone, a locking cone which is arranged externally to the locking cone and which is tensioned by an outer spring, and at least one latch that is pivotal into a position for gripping the equipment by movement of the seat cone and locking cone with the aid of the respective springs.
- the at least one latch can be mounted pivotally on a pivot, whilst the locking cone is arranged slidably on a sleeve, which at the lower end surrounds the seat cone.
- the sleeve can be equipped with balls that are adapted to move from a recess in the lower end of the locking cone to a recess in the upper end of the seat cone. During this movement, the upper edge of each latch is pressed out when the locking cone is released and pressed downwards by the outer spring.
- the lower end of the seat cone is configured having a seat that is intended to rest against an upper end of the equipment for displacing the seat cone along the guide with simultaneous displacement of the locking cone in the opposite direction during actuation of the fishing tool for gripping the equipment.
- Fig. 1 is a schematic illustration of a set-up involving use of the fishing tool, for example, in connection with a drilling procedure;
- Fig. 2 shows a schematic vertical section of the fishing tool in a neutral or loaded position before equipment is retrieved
- Fig. 3 shows the same as Fig. 1, but now in a position immediately prior to gripping the equipment;
- Fig. 4 shows the same as Fig. 1, but now in a position for gripping the equipment
- Fig. 5 is a schematic exploded perspective view of the fishing tool.
- the fishing tool in a typical arrangement, is suspended from a cable 3 or the like inside, for example, a drill string 4 which has been passed through a turret 5.
- the cable 3 is let out or drawn in with the aid of a cable drum 6 with release brake and runs over a rack 7.
- the drum is shown here operated manually, but can of course instead be equipped with motor operation of a suitable type.
- the length of the cable determines how far down in the borehole, not illustrated, the fishing tool can be lowered for retrieval of the equipment 1.
- the cable is connected to the tool via, for example, an attachment means 25 in a top connector on the tool. See Fig. 3.
- the tool comprises a seat cone 10 which is slidably mounted on a guide 20 which at an upper end is fastened in a suitable manner to the top connector 24.
- the seat cone In the position that can be seen from Fig. 2, i.e., prior to catching the equipment 1 down in the borehole, the seat cone is pushed down by an inner spring 11 against a contact face that projects at the lower end of its guide.
- the seat cone is further configured at its lower end with a seat face 20 which is intended to trigger actuation of the tool when the seat face meets the upper end of the equipment. See Fig. 3.
- the tool has a locking cone 12 which is arranged external to the locking 5 cone, and which is tensioned by an outer spring 13, as shown in Fig. 2.
- the locking cone is arranged slidably on a sleeve 16 which at its lower end surrounds the seat cone. The downward movement of the locking cone for actuation of the fishing tool and subsequent gripping of the equipment 1 is effected by the outer spring.
- the sleeve is fastened at an upper end to the top connector 24 in any suitable way.
- the fishing tool is equipped with at least one latch 14 that is pivotally mounted to a pivot 15, in such a way that the latch pivots to the position that is shown in Fig. 4 by reciprocal displacement of the seat cone 10 and the locking cone 12 with the aid of the respective springs 11, 13.
- the lower end of the latch iss configured with a profile that is adapted to be connected to a correspondingly shaped portion 2 at an upper end of the equipment 1 when it is gripped.
- the configuration of inclined faces in the profile facilitates, inter alia, the movement of the seat cone towards a bottom face of the sleeve 16 along which the locking cone 12 is simultaneously displaced.
- the locking cone is equipped with a lower taperQ that is terminated in a substantially vertical portion. This thus causes a pivoting of the latch about the pivot prior to the resultant gripping of the equipment when the seat cone has been moved to the end position with the aid of the outer spring 13. See Fig. 4.
- the sleeve 16 is equipped with balls 17. As shown in Fig. 2, the balls are located partly in a recess 18 at the lower end of the locking cone, and are then transferred in order partly to move to a recess 19 in an upper end of the seat cone (see Fig. 4) in the course of the reciprocal movement of the seat cone and the locking cone for the resultant gripping of the equipment by means of the atQ least one latch.
- the present invention provides a fishing tool that can easily be actuated simply by contact between the seat face and the upper end of the equipment that is to be fished for retrieval to the surface above the5 borehole.
- This contact causes the seat cone and locking cone to enter reciprocal displacement along the guide and the sleeve respectively by means of elastic force in the inner and outer spring. See Fig. 3.
- the result of this initial contact is thus that the at least one latch pivots from the original position in Fig. 3 to the gripping position in Fig. 4 for gripping the upper portion of the equipment that is to be recovered.
- the fishing tool may in a non-illustrated way be equipped with:
- a safety mechanism to prevent movement of the seat cone before contact with the equipment is secured. an adaptation to an internal or external profile on the equipment.
