Description
Technical field
The present invention relates to wellhead assembly, be specifically related to a kind of natural gas twin-well mouth device.
Background technology
It is big that the space is not only taken up an area of in the individual well gas production, and production efficiency is low, and cost of production is also high; Especially gas production working platform in ocean takes up room greatly, and the working platform construction cost is big, and operating maintenance is also inconvenient; Usage quantity that the more important thing is single valve is many, and pad is also corresponding many, and leakage point is also many.
Summary of the invention
The objective of the invention is to: a kind of natural gas twin-well mouth device is provided, and this natural gas twin-well mouth device has adopted casing head and trach head integrated design, has reduced the height of complete machine; Christmas tree master latus rectum direction is designed to a whole main valve, adopts the integrated valve structure at the complete machine flank, is furnished with safety valve; Remote controlledly close automatically; Ensure safety in production, reduced taking up room and reduced connection and the leakage point between the single valve simultaneously, realize installing on well of drilling team two cover gas recovery facilities; Improve production efficiency, practiced thrift the gas production cost.
Technical solution of the present invention is: this natural gas twin-well mouth device comprises christmas tree cap assembly, monolithic main valve, the safety valve that surges, one-piece side flutter valve, instrument flange, choke valve, upper flange, manual flap type A, manual flap type B, manual flap type C and supporting seat; Manual flap type C and manually flap type B and manually flap type A are installed on supporting seat, the monolithic main valve are installed on valve body and are surged safety valve and one-piece side flutter valve.
In the natural gas twin-well mouth device of the present invention, install flange in the bottom of valve body.
In the natural gas twin-well mouth device of the present invention, christmas tree cap assembly is installed on the top of valve body.
In the natural gas twin-well mouth device of the present invention, at other instrument flange and the choke valve installed of one-piece side flutter valve.
In the natural gas twin-well mouth device of the present invention, be furnished with the safety valve of surging, remote controlledly close automatically; Ensure safety in production, reduced taking up room and reduced leakage point, realize installing on well of drilling team two cover gas recovery facilities; Improve production efficiency, practiced thrift cost for oil production.
