Description
Technical field
The present invention relates to oil extraction in oil field field of engineering technology, belong to horizontal well cable arrangements a kind of and discharge success rate height, simple in construction, horizontal well cable presetter device that space availability ratio is high.
Background technology
Cable used by present stage automation downhole hardware is and is arranged horizontally under the outside binding of oil pipe, under fashionable cable easily there is the situations such as breakage with tube wall scratching；Especially when cable is by horizontal well inclination section, being easily rolled fracture, so that failure transferred by cable, prior art cannot solve this problem.
Summary of the invention
It is an object of the invention to design one prevent from rolling during horizontal well cable arrangements, being wound around and crack conditions, improve oil pipe space availability ratio, and the cable horizontal well cable presetter device by horizontal well inclination section success rate can be simplified.
The present invention is achieved through the following technical solutions: it by top connection, fishing head, sealing ring, salvaging headstock, break pin, copper ring, cut off key seat, bearing dead ring, bearing, baffle plate, central tube, cable ejector, pin for suppressing metal, overcoat, anti-rotary seat, stop pin, adapter sleeve, sealing ring, clamp nut, lower contact, cable form；Wherein top connection is sequentially connected with from top to bottom and cuts off key seat, overcoat, adapter sleeve, lower contact, cable；Cable is fixed on salvaging headstock with copper ring by fishing head by screw thread, and salvaging headstock is fixed on by break pin to be cut off on key seat；Bearing fastening is sequentially connected with bearing, baffle plate, central tube, cable ejector from top to bottom；Bearing dead ring, baffle plate cooperate fixing bearing, and reserve the gap of outgoing cable on baffle plate, and baffle plate can be with bearing rotary, and cable is fixed on anti-rotary seat by pin for suppressing metal by screw thread and copper ring；Anti-rotary seat, clamp nut are with central tube threadeds, stop pin and adapter sleeve matched in clearance；Cable is wrapped on central tube, and is fixed by baffle plate, cable ejector and overcoat.
Fishing head has center and crosses cable passage, and cable directly can be crossed cable passage from center and pass through.
Baffle plate, central tube, cable ejector cooperatively form an annular space, and cable is closely arranged in this space in ring-wound mode.
Compared with the prior art the present invention has the advantage that
The present invention uses and enters mode under preset cable, and cable passes through inside oil pipe and other downhole tools, improves cable and goes into the well security；Cable discharges from the inner to the outer, and cable will not be occurred during salvaging to be wound around situation about blocking；Break pin form discharges, and fishing success ratio is high.
Accompanying drawing illustrates:Fig. 1 is present configuration schematic diagram.
In figure: 1-top connection, 2-fishing head, 3-sealing ring, 4-salvaging headstock, 5-break pin, 6-copper ring, 7-cut off key seat, 8-bearing dead ring, 9-bearing, 10-baffle plate, 11-central tube, 12-cable ejector, 13-pin for suppressing metal, 14-overcoat, 15-anti-rotary seat, 16-stop pin, 17-adapter sleeve, 18-sealing ring, 19-clamp nut, 20-lower contact, 21-cable.
Detailed description of the invention:See Fig. 1: the present invention by top connection 1, fishing head 2, sealing ring 3, salvage headstock 4, break pin 5, copper ring 6, cut off key seat 7, bearing dead ring 8, bearing 9, baffle plate 10, central tube 11, cable ejector 12, pin for suppressing metal 13, overcoat 14, anti-rotary seat 15, stop pin 16, adapter sleeve 17, sealing ring 18, clamp nut 19, lower contact 20, cable 21 form；Wherein top connection 1 is sequentially connected with from top to bottom and cuts off key seat 7, overcoat 14, adapter sleeve 17, lower contact 20, cable 21；Cable 21 is fixed on salvaging headstock 4 by fishing head 2 by screw thread and copper ring 6, salvages headstock 4 and is fixed on by break pin 5 and cuts off on key seat 7；Bearing fastening 8 is sequentially connected with bearing 9, baffle plate 10, central tube 11, cable ejector 12 from top to bottom；Bearing dead ring 8, baffle plate 10 cooperate fixing bearing 9, and reserve the gap of outgoing cable on baffle plate 10, and baffle plate 10 can rotate with bearing 9, and cable 21 is fixed on anti-rotary seat 15 by pin for suppressing metal 13 by screw thread and copper ring 6；Anti-rotary seat 15, clamp nut 19 are with central tube 11 threadeds, stop pin 16 and adapter sleeve 17 matched in clearance；Cable 21 is wrapped on central tube 11, and is fixed by baffle plate 10, cable ejector 12 and overcoat 14.
Fishing head 2 has center and crosses cable passage, and cable 21 directly can be crossed cable passage from center and pass through.
Baffle plate 10, central tube 11, cable ejector 12 cooperatively form an annular space, and cable 21 is closely arranged in this space in ring-wound mode.
During onsite application, first on ground, Len req cable 21 is wrapped on central tube 11 by " zigzag ", fishing head 2 leads to the inner side cable 21 near central tube outer wall, what cable ejector 12 was drawn is then the outermost cable 21 near overcoat 14, avoids occurring cable 21 to extend out the situation sending out inner and outer cable extrusion when so drawing；Assemble this device, enter under tubing string and by fishing head 2, cable 21 is drawn from down-hole afterwards, it is achieved the oil pipe release process of cable 21.During cable 21 release, owing to there being the existence of bearing 9, cable 21 can be gone into the well along with winding direction rotates release, it is to avoid occurs cable to intersect situation about blocking.
