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。
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 of33. 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 inthis paper.
