Structure and principle of the office (2 1) Structure. ( 2) The principle of office. 。 Q: introduction of sucker rod cock a: abstract: in order to solve the next encounter blowout from time to time in the process of sucker rod gauge way than rob spray when problems, research has made the cock sucker rod. In more than 20 Wells of high pressure oil and gas Wells to rob a spray on the success rate of 100 one hundred percent, with remarkable economic benefit and society benefit. The treatment method of complex operation, the intensity of labor is big, the whole process needs at least 10 ~ 20 min, refuses to soil and water well control requirements, pay may cause pollution of the background, and also become the hidden danger of safety production. Should be paid attention to in the use of the following: (1) the present should be documented in the process of sucker rod under the well sucker rod of phase match with buckle joint; (2) rod plug valves to maintain cleaning, in good condition, regularly test, protect the aftercare. The device is on the basis of the tubing plug valves and have the quality light, simple operations and grab gush fast unique places, such as the present attempt to use, the effect is satisfactory. The structure of the device is on the basis of oil pipe plug, lower connections to improve short answer. Improve the sub bottom connecting clamp head, lengthened clamp head bottom button for tubing a sucker rod joint, buckle joint is equipped with four connecting holes, can successfully put spray and wash, kill the office industry. Site keywords: plug valves; Sucker rod; Spray; Structure under 1 preface oilfield workover operations on sucker rod in the process, if found wellhead overflow or blowout one million head, usually grab with polished rod blowout box, wellhead installation process or cast rod directly into the wellbore to wash well, pressure well as industry. 4 try to sucker rod present cock from June 2008 to April 2009 have been drilling for oil in shengli oilfield co. , LTD. In the enterprise set factory work brigade promotion use, high pressure oil and gas well in more than 20 mouth rob a spray on the success rate of up to 100 one hundred percent, and show high efficiency, agile and safe unique place, with remarkable economic benefit and society benefit. 3 the main technical parameter of screw rod village the main technical parameter as follows: diameter: 105 mm; Fixed office pressure: 25 MPa; Joint screw on QQ: 2 7/8 TBG; Under the joint screw type QQ: CYG7/8; The fixed load: 10 t; The total length: 600 mm. Sucker rod blowout under one million head, only need to put a Marine on the wellhead four-way valve small rims, cock to sucker rod with the sucker rod coupling in the well, improve the nipple of the cock, remove the back of the sucker rod elevator door on the cross, the well card clamp, screw quickly, close the cock, to complete the construction of the well.
