Description
Art:
The utility model relates to the preventer hermetic seal test of oil field snubbing serving equipment.
Background technology:
Along with going deep into of unconventional energy resource exploitation, in order to ensure the high yield of each oilfield, stable yields, extraordinary workover treatment increases just day by day, also more and more higher to the requirement of equipment and operation technique, therefore snubbing serving equipment is a kind of novel workover rig, it carries out operation to Oil/gas Well in no killing well situation, it is a kind of stable yields, energy-conservation, environmental protection, the equipment of operation broad covered area, so can critical component preventer live the gases at high pressure of down-hole by effective sealing in tubing reciprocation process, it is the key point that equipment normally works, if preventer sealing does not live the gases at high pressure in well, equipment just cannot carry out operation, the gas spilt can cause serious accident, therefore measure preventer gas sealing ability and seem particularly important.
Owing to market not being tested preventer hermetic seal equipment, the sealing property of its glue core cannot detect, and governs the application of pressure balance work over rig in gas well
Summary of the invention:
The object of the utility model, is to provide one and can measures preventer gas sealing ability, and after mainly detecting that preventer seals oil pipe, the gas sealing ability of oil pipe in moving up and down, also can detect the gripping performance of slips assembly simultaneously.
The utility model realizes above-mentioned purpose by following technical solution:
Preventer hermetic seal test unit, it is characterized in that: this device is made up of melt pit, base, admission gear, actuator cylinder, slips Connection Block, adapter sleeve, erection device, described base is the tower structure that rectangular tube is welded, connect actuator cylinder by web joint, middle part is welded with 1 Connection Block and connects admission gear; Admission gear is that upper and lower flange welding forms, and lower flange is blind hole, and side has a high pressure admission hole; Web joint bolt-connection on actuator cylinder bottom and base, piston rod top by screw thread with connect adapter sleeve bottom and through slips Connection Block, actuator cylinder and slips Connection Block connected as one; Connect with slip assemblies with bolt in the middle part of slips Connection Block; Mandrel lower end is connected with preventer, and upper end is connected through slip assemblies and support bar; Erection device is made up of righting channel-section steel and fixed head, and channel-section steel inner groovy contacts with the screw rod of actuator cylinder, and fixed head is fixed by bolts in the threaded hole of preventer.
During use, base is placed in melt pit, Connection Block loads admission gear, admission gear loads preventer and each gasket ring, with the good each connector of bolted; 4 actuator cylinder bolted are loaded onto tight at the web joint at base corner place; After erection device channel-section steel groove is contacted contraposition with the screw rod on actuator cylinder, with bolt, channel-section steel is fixed tightly on fixed head, then by fixed head bolt tightening on preventer; Cylinder piston rod upper end loads adapter sleeve, tightens up after slips Connection Block corner bolt hole is inserted in adapter sleeve with nut; With bolt, slip assemblies is fixed on slips Connection Block; With pin, support bar is fixed on mandrel upper end, in overall loading preventer.
When measuring preventer hermetic seal test, connect, mix up each liquid gas circuit pipeline, pump valve starts high-pressure pump, high pressure gas enters from admission gear's air intake opening, high pressure gas produces thrust upwards to bottom surface bottom mandrel, make piston rod upwards uniform motion, drive slip mechanism to clamp mandrel to move upward, mandrel is in up process, and whether sealing place watching rubber core of lubricator and mandrel has leakage; In descending operating mode, reversing valve operated, piston rod drives the clamping mandrel that moves down of the slip insert in slip mechanism that piston rod is moved downward, and drives slip mechanism to clamp mandrel and moves downward, check whether sealing place of rubber core of lubricator and mandrel has leakage.
The beneficial effects of the utility model:
Adopt the actual job operating mode of preventer hermetic seal test unit simulation preventer, measure the sealing property of mandrel motion process rubber core of lubricator up or down, and structure is simple, handling safety and convenient.
