Introduction of pneumatic valve rod cock 3)

abstract: the traditional method problem rob spray, not timely development pole cock pneumatic valve in order to solve the blowout situation in the process of from the pole. The equipment in the pipeline is based on plug-in processing, light weight, simple operation, rapid spray characteristics and field experiment, the effect is good. Over years of oil and gas Wells and high pressure spray in the % of success rate have significant economic and social benefits, taking construction of port. Key words: plug; Bar; The international balance of payments; Structure description from the pole, in the process of oilfield workover overflow or warning if it is found that the well blowout, it is usually installed shaft blowout box, wellhead installation process, or directly to the bar, and then thrown into the wash well well, well. The measure is complex, labor-intensive, the entire process takes at least? Minutes, cannot satisfy the requirement of well control, not only may cause environmental pollution, but also a safety hazard. Sinopec shengli oilfield co. , LTD. , in the plate production brigade lever blowout preventer developed a plug-in, light weight, simple operation, easy to use and quick spray system, and can adapt to the various requirements of the stem spray. Through the field test, minutes wellhead control can be realized, well control effect is good. Structure and working principle, ） Structure. The device structure is based on the crude oil pipeline a cock, and then reduce the elevator link. To further strengthen department took a short extension clamp connection head, tubing head and a connection rod button at the bottom of the change, change the button has four holes connected joints, washing machine achieve blowout caused construction work, clip. （ ） Work. Blowout just from the stem in a about a four to small rims of the well, warning congestion well sucker rod and the associated, and elevator access of the pneumatic valve, elevator door rod stone removal hole on the back of the card on the pliers, screw down the bolt, close the cock, do well construction. Three, the main technical parameters of pneumatic valve rod rotation main technical parameters are as follows: diameter: mm; The rated working pressure: mpa; Button in the threaded connector type: / TBG; Depending on the type of thread joint thread: CYG /; Load rating: tons; Total length: mm. Year/month to/year/month has been used in field test cock sucker disk production brigade action in the shengli oilfield co. , LTD. , promote % more than a port in robbery, used in high pressure spray oil and gas Wells construction success rate and display of efficient, fast, security features, with significant economic and social benefits. In use should be paid attention to the following: (1) the scene from the rod should be prepared, to match the deduction and sucker rod joint variables; (2) pole plug should be kept clean and in good condition, regular pressure testing, maintenance.
