| 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 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. |
