Description
Technical field
The utility model relates to oilfield test technical field, and particularly a kind of decentralized wellhead rod-pumped well safety lifting solution twines device.
Background technology
The test of rod-pumped well decentralized wellhead has two kinds of modes usually: one, well logging Φ 12.7mm or Φ 8.0mm cable connection logging instrument are to each layer bit test of downhole perforation; Two, test steel wire mounting pressure gauge and carry out pressure monitoring in the middle part of oil reservoir.Carry out in test construction, sometimes because a variety of causes (as foreign matter and test cable, steel wire winding oil pipe etc. in oil, casing corrosion distortion, pipe column tools distortion, tubing string), after test construction terminates, annular water detector, test pressure meter twine well or blocked portion in oil well eyelet thimble space, downhole instrument cannot normally trip out from decentralized wellhead, instrument twines well, meets card position sometimes at well head, several meters sometimes, tens meters, hundreds of rice, upper km.Tester cannot normally trip out, and directly causes consequence to be that test pressure meter data cannot normal playback, affects proper testing production and construction; Indirect consequence is that tester cannot normal circulation use, especially some microtest instruments.
Summary of the invention
Technical problem to be solved in the utility model overcomes in the decentralized wellhead rod-pumped well test that exists in background technology to have that solution twines, the problem of unfreezing difficulty, and provide a kind of decentralized wellhead rod-pumped well safety lifting solution to twine device, this decentralized wellhead rod-pumped well safety lifting solution twines device, improve instrument and recycle rate, realize the timely solution of safety to twine, take off card, meet oil well and normally produce.
The invention for solving the technical problem reaches by following technical scheme: this decentralized wellhead rod-pumped well safety lifting solution twines device, comprise Christmas tree wellhead sleeve pipe, oil pipe four-way, flange, casing coupling support cross arm, hydraulic jack, tubing coupling connection cross-arm, oil pipe four-way connected pipes, Christmas tree wellhead sleeve pipe, Christmas tree wellhead sleeve pipe is by flange splicing sleeve box cupling, described oil pipe four-way lower connection pad sheet group, shim pack bottom connected pipes box cupling connects cross-arm, and Christmas tree wellhead casing coupling external card has casing coupling support cross arm; Casing coupling support cross arm top is connected support hydraulic pressure between cross-arm with tubing coupling very heavy, is connected to wellhead flange dish spacer pin between tubing coupling connection cross-arm and flange; Wellhead flange dish spacer pin bottom is arranged on the screw hole of flange above and below; The upper and lower interplanar of flange is equipped with wheel ball bearing rolling bearing.
The utility model can have following beneficial effect compared with above-mentioned background technology: this decentralized wellhead rod-pumped well safety lifting solution twines device owing to adopting said structure, unfreezing efficiency is high, cost is low, can solve rapidly that instrument twines, card problem, solve in time and twine well instrument, easy to operate, install simple, safety is high.Improve instrument service efficiency, well information is measured in admission in time, ensures to produce and normally carries out in order, have good indirect economic effect.

Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1, oil pipe four-way, 2, shim pack, 3, tubing coupling connects cross-arm, 4, wellhead flange dish spacer pin, 5, flange, 6, wheel ball bearing rolling bearing, 7, hydraulic jack, 8, casing coupling support cross arm.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this decentralized wellhead rod-pumped well safety lifting solution twines device and comprises Christmas tree wellhead sleeve pipe, oil pipe four-way 1, flange 5, casing coupling support cross arm 8, hydraulic jack 7, tubing coupling connection cross-arm 3, oil pipe four-way 1 connected pipes, Christmas tree wellhead sleeve pipe, Christmas tree wellhead sleeve pipe is by flange 5 splicing sleeve box cupling, described oil pipe four-way 1 lower connection pad sheet group 2, shim pack 2 bottom connected pipes box cupling connects cross-arm 3, and Christmas tree wellhead casing coupling external card has casing coupling support cross arm 8; Casing coupling support cross arm 8 top is connected cross-arm 3 support hydraulic pressures very heavy 7 with tubing coupling, be connected to wellhead flange dish spacer pin 4 between tubing coupling connection cross-arm 3 and flange 5; Wellhead flange dish spacer pin 4 bottom is arranged on the screw hole of flange 5 above and below; The upper and lower interplanar of flange 5 is equipped with wheel ball bearing rolling bearing 6.
Described casing coupling support cross arm is two identical half cylinder compositions, and by both sides, totally four diameter screw and fastening nuts are integrated, for blocking casing coupling, support hydraulic pressure is very heavy, circular hole is locating hole under hydraulic jack, avoids very heavy side to fall, realizes hydraulic jack stable operation; Described hydraulic jack realizing oil pipe column lifting, falling steadily, for relying on casing coupling, by tubing coupling load-bearing coupling part lifting oil pipe tubing string; Wheel ball bearing rolling bearing, by being arranged among the upper and lower plane of tubing-head adapter flange dish, reaching well mouth oil pipe tubing string and facilitating rotating function, conveniently solving instrument; Described tubing coupling connects cross-arm, be made up of two parts, one is two independence rectangular band half arc column bodies, and another part is that the hollow square iron of two rectangular half arc column bodies is fixed at two, and effect is delivered on production tree tubing head box cupling single for hydraulic pressure two dynamic very heavy stress point with lifting oil pipe tubing string.The hollow square iron of half arc column body plays fixing very heavy top connection effect, avoids very heavy side to fall, realizes hydraulic jack stable operation; Described wellhead flange dish spacer pin, prevent oil pipe column from lifting process, departing from original position, by being arranged on upper and lower flange screw hole, prevent in lifting oil pipe tubing string process, tubing string center of gravity does not produce tubing string deflection between two parties, guarantee after solution twines, upper and lower wellhead flange dish safe return simultaneously.
This decentralized wellhead rod-pumped well safety lifting solution twines device, avoids operation to the adverse effect of producing well and protect well site environment.Unfreezing efficiency is high, and cost is low, can solve rapidly that instrument twines, card problem, solves in time and twines well instrument.Eccentric annulus instrument unfreezing success rate reaches 100%, and eccentric annulus pressure measurement instrument unfreezing success rate is 90%.
