摘要

渤海湾QHD32-6油田,为解决疏松软地层取心困难、收获率低的问题,引进美国DBS公司的全关闭取心工具(Posiclose),取心5筒,进尺33.10m,心长27.45m,平均岩心收获率82.93%,比常规的海洋250P系列取心工具提高48个百分点。文中介绍了全关闭取心工具的基本结构、主要技术参数、工作原理及现场使用情况。

Abstract

In order to resolve the problem of difficulty coring operations with low recovery rate in loose and soft formations in QHD-6 reservoir of Bohai Golf, an American Posiclose Coring Tool was imported and five coring operation trips of the total coring footage of 33.10 m were conducted. The total core length was 27.45 m and the recovery rate was 82.93%, by 48% higher than using the conventional 250 P coring tool. Its basic structure, technical specifications, working mechanism and rig-site application results were presented in this paper.
