摘要
无控状态下的换装井口作业是试油期间存在的最大安全风险。可回收式套管堵塞阀可确保有控状态下的换装井口作业,它主要由中心管、摩擦块、卡瓦、胶筒、击落塞和下接头组成。规格为177.8mm、200.03mm套管堵塞阀的工作压差为52 MPa;堵塞阀旁通流道面积为54.6cm2;可实现套管内压力检测并进行压井作业;同时可以安全回收。
Reloading wellhead operation under non-control condition is a big safety risk in the course of oil testing.Consisting of central tube,friction block,slips,rubber sleeve,plug and lower Joint,recyclable casing jamming valve ensures a controllable condition for such an operation.With the size of 177.8mm or 200.03 mm,it works under differential pressure of 52 MPa and its bypass flow area is 54.6cm2.By using it,inner-casing pressure measurement and kill operation can be done.
