Description
Technical field
The utility model relates to oil gas field oil recovery, production gas technology field, and particularly a kind of ground restriction choke is a kind of throttle device of regulating the oil gas well production of carrying out under not stopping production situation.
Background technology
At present, in the oil gas field manufacturing process, because the parameter of each mouthful well is different, this just needs each well yield of control, and control method is to adopt throttle nozzle, and limited flow prevents the too fast reduction of strata pressure.The natural gas of underground extraction, crude oil or water contain a certain amount of impurity such as silt particle, in high pressure and quick course of conveying, silt particle produces erosive wear to feed-line and equipment, shortens its application life, seriously jeopardize the person and property safety, and that throttle nozzle is subjected to erosive wear is the most serious.
The utility model content
The purpose of this utility model is: a kind of multiinjector transposition restriction choke is provided, realizes multistage Flow-rate adjustment under situation about not stopping production.Because key components and parts adopted special ceramic materials, can protection against erosion, wear-resistant, greatly improved application life.
The technical solution adopted in the utility model is: multiinjector transposition restriction choke, mainly form by spanner, plug, axle, throttle nozzle seat, seal disc, opening, throttle nozzle and housing, and it is characterized in that:
Housing is that the right-angle type threeway is tubular, and there is flange the vertical tube end of tee piece, can connect outlet line; In straight tube one end of tee piece dividing plate is arranged, an opening is arranged on dividing plate; Fix a circular seal dish in the straight tube of tee piece and at the medial surface of dividing plate, seal disc has upright opening; The opening of dividing plate and UNICOM relative with the upright opening of seal disc.In the another side of seal disc a throttle nozzle seat is arranged, evenly distributing on the throttle nozzle seat is fixed with 6～10 throttle nozzles, and 6～10 throttle nozzles are circumferential arrangement, and during swivel flow nozzle seat, throttle nozzle can be respectively and the upright opening UNICOM of seal disc.The throttle nozzle seat has centre bore, and axle one end penetrates throttle nozzle seat centre bore and is fixed together in the throttle nozzle seat.
Straight tube other end screw thread at tee piece is fixed with a plug, and the other end of axle passes the plug centre bore, is fixed with rotary spanner in the end of axle.Rotating spanner can drive axle, throttle nozzle seat and throttle nozzle and rotate.
To seal in order making between seal disc and the housing, on the outer wall of seal disc, sealing ring to be arranged.
Be connected for flat key between shaft end and the throttle nozzle seat.
Be with the erosion control ring on the throttle nozzle seat, the external diameter of erosion control ring is identical with the straight tube internal diameter of tee piece, is with the butterfly spring on axle, and the butterfly spring promotes the throttle nozzle seat and compresses seal disc.
Two bearings are arranged between axle and plug.
On the end face of the straight tube of tee piece, be fixed with dial, can show the position that throttle nozzle seat and throttle nozzle rotate.
End at axle is fixed with nut, and nut is between spanner and dial.
The beneficial effects of the utility model: the utility model multiinjector transposition restriction choke, the throttle nozzle that has a plurality of different-diameters on the throttle nozzle seat 7, adopt manual, electronic, surge or the pneumatic actuation mode, pass through rotating spanner, the throttle nozzle seat is rotated, the throttle nozzle of changing different-diameter of not stopping production is relative with the upright opening of seal disc, produces different restriction effects; Throttling, sand controlling result is good and have multistage regulatory function; Crucial zero-bits such as flow nipple, erosion control ring have adopted wear-resisting, resistant to elevated temperatures special ceramic materials, have the accurate and abrasion resistance energy of throttling, and whole service life has obtained large increase.Also be applicable to other gases or liquid line throttling.
