The utility model discloses slot on the slips cover of well slips subassembly and pressure equaliser's the seal cover, two grooves flush to solved the engineering practical problem that the cable conductor can't pass the oil pipe anchor, reduced the processing degree of difficulty simultaneously, reduced the power of sitting the anchor, lifted and transfer oil pipe and do not lead to the fact the injury to the cable.
Description
Technical field
The utility model relates to the downhole tool of a kind of oil field petroleum works, and especially one crosses cable tubing anchor.
Background technology
Nearly two during the last ten years, and measuring technology is more and more wider in the application in petroleum works field.When oil overpressure is excessive, traditional tubing anchor sometimes midway is disanchored.And the limited annular space between oil pipe and sleeve pipe takies by traditional tubing anchor completely, cause the cable of testing tool to enter down, hinder the application of measuring technology in petroleum works field.Eccentric tubing anchor allows cable pass by spiling on eccentric central tube and solves this problem, but but causes structural large adjustment, reduce piston area and increase the power of sitting anchor, and eccentric central tube difficulty of processing is large.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of can reduce difficulty of processing and midway can be avoided to disanchor cross cable tubing anchor.
In order to solve the problems of the technologies described above, the utility model comprises central tube and is arranged on top connection and the lower contact at the upper and lower two ends of central tube, a piston is also provided with between described central tube and top connection, a lock ring is provided with in the middle part of this piston outer wall, described piston exterior is also set with a piston bush, this piston bush upper end be connected with one with lock ring with the use of lock tube, lower end is connected with an adapter sleeve;
Described central tube outer wall is set with upper cone, slip assemblies and pressure equaliser, and described slip assemblies comprises slip sleeve, slips and garter spring, and described pressure equaliser comprises lower cone, cuts ring and sealing shroud;
Described upper cone upper end is by sitting anchor shear pin and described adapter sleeve is affixed, lower end taper surface is pressed on slips top through slip sleeve, and described anchor shear pin of sitting is cut off that rear adapter sleeve is descending to be pressed on upper cone outward flange and to drive the descending extruding slips of upper cone to realize slip assemblies grappling;
Described lower cone is arranged on central tube outer wall by cutting ring, described sealing shroud is fixed on central tube outer wall, described lower cone upper end is pressed on slips bottom through slip sleeve, lower end is inserted in sealing shroud, described central tube, between lower cone and sealing shroud, be formed with an annular seal space, described central tube outer wall have the aperture that multiple and described annular seal space is communicated with;
Described slip sleeve with sealing shroud has power supply cable by and the groove be connected with testing tool below.
The beneficial effects of the utility model are: the utility model is slotted on the slip sleeve and sealing shroud of tubing anchor, and two grooves flush, thus solve the engineering problem that cable can't pass tubing anchor.Meanwhile, reduce difficulty of processing, reduce the power of sitting anchor, above put drain line and cable is not damaged.Devise by lower cone, cut ring, pressure equaliser that sealing shroud forms, fluid with pressure, by central tube bottom aperture, provides a power upwards to lower cone, balances the power that a part is downward, avoid pressure excessive and cut off ring, causing midway to disanchor.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model crosses cable tubing anchor.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
See Fig. 1, cable tubing anchor of crossing of the present utility model comprises central tube 6 and is arranged on top connection 1 and the lower contact 16 at central tube about 6 two ends, a piston 2 is also provided with between described central tube 6 and top connection 1, a lock ring 5 is provided with in the middle part of this piston 2 outer wall, described piston 2 outside is also set with a piston bush 4, this piston bush 4 upper end be connected with one with lock ring 5 with the use of lock tube 3, lower end is connected with an adapter sleeve 7;
Described central tube 6 outer wall is set with upper cone 9, slip assemblies and pressure equaliser, and described slip assemblies comprises slip sleeve 10, slips 11 and garter spring 12, and described pressure equaliser comprises lower cone 13, cuts ring 14 and sealing shroud 15;
Described upper cone 9 upper end is affixed with described adapter sleeve 7 by sitting anchor shear pin 8, lower end taper surface is pressed on slips 11 top through slip sleeve 10, and described anchor shear pin 8 of sitting is cut off that rear adapter sleeve 7 is descending to be pressed on upper cone 9 outward flange and to drive the descending extruding slips 11 of upper cone 9 to realize slip assemblies grappling;
Described lower cone 13 is arranged on central tube 6 outer wall by cutting ring 14, described sealing shroud 15 is fixed on central tube 6 outer wall, described lower cone 13 upper end is pressed on slips 11 bottom through slip sleeve 10, lower end is inserted in sealing shroud 15, described central tube 6, between lower cone 13 and sealing shroud 15, be formed with an annular seal space, described central tube 6 outer wall have the aperture that multiple and described annular seal space is communicated with;
Described slip sleeve 10 with sealing shroud 15 has power supply cable by and the groove be connected with testing tool below.
Tubing anchor with under oil pipe to after predetermined well depth, pitching is suppressed inner tube pressure and is raised, hydraulic pressure imports in the annular space between piston 2 and central tube 6 by the liquid pass hole on central tube 6 top, after arriving certain pressure, sit anchor shear pin 8 to be cut off, piston bush 4 promotes upper cone 9 and moves downward, and lock ring 5 and lock tube 3 are fixed together, and slips 11 is extruded to open and is anchored on oil pipe.Upper lifting pipe post, cuts off ring 14, and slips 11 retraction is disanchored.The slip sleeve 10 and sealing shroud 15 of tubing anchor have groove, and the groove at two places flushes, and cable by the groove connection testing tool below at two places on tubing anchor, can be convenient to oilfield test operation.
Cutting before ring cut off, the fluid of band pressure, by central tube 6 bottom aperture, provides a power upwards to lower cone, balances the power that a part is downward, avoids pressure excessive and cut off ring, causes midway to disanchor.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiments are all included within scope of the present utility model.
