摘　　要：近几年,井下套管封井器是作为一种用于全过程欠平衡钻井的核心工具,得到了一定程度的推广应用,但美国威德福公司和我究院的产品,均不具备阀底压力测量功能。为进一步提升井下套管封井器的性能,解决阀底压力的测、传难题,我院开始研制井下套管封井器的二代产品。本文重点介绍了我院开展的可测量阀底压力的Φ244.5mm井下套管封井器的研制情况,如结构设计、系统组成、工作原理及现场应用情况等。Recently years,annulus safe valve is popularly used as one of the nucleus tools during whole - process underbalanced drilling.In domestic market,the technology is only owned by Weatherford and Keramay Drilling Technology Research Institute of CNPC Xibu Drilling Engineering Company Limited,but it has not the pressure measurement function.In order to improve the annulus safe valve performance and resolve the difficulty of pressure measurement below valve,Drilling Technology Research Institute starts to study the second era valve.The paper primarily introduces the tools structure design,system composition and working principle of outside diameter of 244.5mm valve which can measure the pressure below valves and applies in oil field.
