摘要
高压气井采气井口的 1、2、3号控制闸阀常因腐蚀等多种原因产生泄漏 ,对气井的安全生产带来严重危害 ,为了解除采气井口控制闸阀导致的生产不安全隐患 ,研制在油管和大四通旁通中实施暂时堵塞以分别更换 1号和 2、3号控制闸阀的工艺技术 。
No.1.2.3. wellhead control valves of high pressure gas well are often leak because of corrosion etc.cause.It brings serious harm for safety in production of gas well.In order to remove the unsafe hidden danger of wellhead control valve,the technology of replacement No.1 and No.2.3 control valve by executing temporary plugging technique in tubing and major cross piece is developed.Meanwhile,the paper presents the outstanding economic benefit obtained by applying the technology.
