Abstract
The utility model provides a slope mine oil extraction wellhead device for pressure control, opening and closing of the slope mine and the wellhead operation under well. The utility model solves the problems that the prior wellhead can not satisfy all the requirements of the oil extraction of slope mine and a special fracturing wellhead must be used in fracturing and the manipulation is not convenient. The utility model consists of a body and an oil outlet channel, wherein, a flange is arranged on a bushing, a hanger is arranged in the bushing, the hanger is fixed on the flange by a screw, the top of the screw is provided with a cap, a blocking ring and a rubber cushion are arranged between the screw and the flange, a lateral pipe provided with a theftproof vavle is fixed on the bushing communicated with the lateral pipe, a vertical pipe is connected and communicated with a connecting pipe which is provided with a pressure gauge non return valve, a sampling valve is arranged perpendicular to the pressure gauge non return valve, and the theftproof valve is fixed on the connecting pipe by a lathe dog. With the advantages of small volume, compact structure, light weight and convenient manipulation, the utility model can directly fracture without the need to change the wellhead and can be directly in butt joint with a spiral organ.
Description
Technical field:
The utility model relates to the wellhead assembly in the oil recovery field, oil field, is a kind of pressure control that is used for inclined shaft specifically, the device that carries out the well head operation when open and close and underground work.
Background technology:
Well head can not satisfy the requirement that inclined shaft recovers the oil in the past, can not directly dock with circulator behind the last well, will change special-purpose fracture well head ability pressure break during pressure break, inconvenient operation, and complex structure.
Summary of the invention:
In order to solve the problem of above-mentioned existence, the utility model provides a kind of satisfies the pressure break needs, have anti-theft feature and can dock with circulator, inclined shaft wellhead for production simple in structure; Goal of the invention of the present utility model is achieved through the following technical solutions: the inclined shaft wellhead for production: partly be made of body and oil discharge passage, described inclined shaft wellhead for production body construction is: mounting flange on sleeve pipe, hanger is installed in the sleeve pipe, jackscrew is fixed on hanger on the flange, end at jackscrew is provided with pressure cap, be provided with baffle ring and rubber cushion between jackscrew and the flange, transverse tube is fixed on the sleeve pipe, transverse tube communicates with sleeve pipe, and valve for guarding against theft is housed on transverse tube, and the valve for guarding against theft two ends are provided with clip, transverse tube links to each other with the clip head, plug is screwed on the clip head, and with the steel ring sealing, clip is fixed two clip heads between the two clip heads; The structure of oil discharge passage is: standpipe is connected with adapter and communicates, and on taking over the pressure meter ball-and-seat is housed, and with pressure meter ball-and-seat vertical direction sample cock is housed, and with clip valve for guarding against theft is fixed in the adapter.
The beneficial effects of the utility model: the utility model adopts said structure, and transverse tube and flange bolt connect into certain angle, when being connected with circulator angle one to; Flange adopts standard 250 flanges, need not change well head during pressure break and get final product direct pressure break, and can directly dock with circulator; Hanger adopts the standard hanger, and suspended load is big, and interchangeability is good; Hanger adopts the fixing mode of jackscrew, prevents jet pipe; Oil recovery valve one end is clamp connection, directly is connected with circulator during oil recovery, and the other end is that welding point connects, the direct and flow line welding of welding point; Sleeve pipe one side mounting sleeve valve uses during as operation, and opposite side connects for the clip plug, as standby end; Valve all adopts valve for guarding against theft, has only with special spanner and just can open, and plays antitheft effect.The utlity model has that volume is little, in light weight, compact conformation, easy to operate advantage.
