Description
Technical field
The utility model relates to a kind of oil field well pressure measuring power tool, relates in particular to a kind of delaminating pressure testing pressure gauge seating nipple.
Background technology
At present, in oilfield development process, delaminating pressure testing is an important process of oilfield test, seating nipple in China's tradition pressure measurement technology is owing to each outstanding outer working tube 300mm of two ends about the interior seating nipple of assembling, when workover treatment, often cause when being carried on the last oil pipe because swing is subjected to external impacts to cause that the seating nipple lateral bending is out of shape in the pressure measurement seating nipple pipe nipple.Cause pressure gauge to take out difficulty, pressure measurement seating nipple pipe nipple is scrapped, and designs a kind of shock resistance, and the manometric seating nipple of convenient taking-up is a urgent problem.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of delaminating pressure testing pressure gauge seating nipple, is used to solve shock resistance, convenient problem of taking out manometric seating nipple.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of delaminating pressure testing pressure gauge seating nipple, comprise outer working tube, interior seating nipple, fixture, pressure guide hole, last suspension plug, following outer pipe plug, following inner screw plug, threaded mandrel and tubing coupling, interior seating nipple is fixed by fixture and outer working tube, interior seating nipple is connected by pressure guide hole with outer working tube, interior seating nipple is interlinked to the outside by pressure guide hole and delaminating pressure testing pressure gauge seating nipple, the outer working tube upper end is connected with tubing coupling, the seating nipple upper end was connected with interior seating nipple in last suspension plug screwed in, the seating nipple lower end was connected with interior seating nipple in following outer pipe plug screwed in, and following inner screw plug screws in down and is connected with following outer pipe plug in the outer pipe plug.
Two ends, the seating nipple outside are provided with the wrench draw-in groove in described, and two ends, interior seating nipple center inwall is provided with screw thread.
The described plug head that go up to hang is provided with seal groove, on hang plug can to screw in the center, position be hollow, center inner wall is provided with screw thread, on hang plug and can screw in the position arranged outside screw thread is arranged.
Described outer pipe plug head down is provided with seal groove, and following outer pipe plug center is that entire body is hollow, and center inner wall is provided with screw thread, and following outer pipe plug can screw in the position arranged outside screw thread.
Described inner screw plug head down is provided with seal groove, and following inner screw plug can screw in the position arranged outside screw thread.
Described threaded mandrel is provided with screw thread, and threaded mandrel can be by seating nipple in outer pipe plug screws in down.
Described fixture center is provided with central through hole, is provided with through hole around the central through hole.
Technological merit of the present utility model and beneficial effect are:
1, interior seating nipple has shortened the length of exposing outside outer working tube, and seating nipple is subjected to the pressure measurement seating nipple pipe nipple loss from spoilage that the external impacts distortion causes in effectively preventing when workover treatment.
2, pressure gauge is suspended in that to hang on the plug stationarity good, prevents that the pressure gauge battery pack that play may cause in interior seating nipple from contacting bad outage phenomenon, guarantees to test one-time success rate.
3, it is convenient and swift to get pressure gauge, lays down to hang plug and can take pressure gauge out of.
4, when have the oil of coagulating to freeze cold season autumn and winter, the timing of pressure power, the detachable inner screw plug that falls down steadily ejects pressure gauge with threaded mandrel, stops methods violating the regulations such as baked wheaten cake and rod member bump, and protection pressure gauge safety increases the service life.
The utility model improves safety, operating efficiency and the test one-time success rate of delaminating pressure testing; reduced labour intensity; protect delaminating pressure testing pressure gauge seating nipple, prolonged delaminating pressure testing pressure gauge seating nipple application life, can produce the characteristics of huge economic benefit.
