自1996年以来,上海海洋石油局"KT-2"钻井平台在渤海海域测试施工了8口钻井,本文介绍了测试过程中的主要经验教训,内容涉及①原钻机抽汲;②MFE工具;③压力计量程;④井下遇阻;⑤反循环阀;⑥油气外喷;⑦管柱设计;⑧冬季施工防冻;⑨开关井操作;⑩工具落井等,并逐一作了分析。

The "KT-2" rig, which is owned by Shanghai Offshore Petroleum Bureau, has finished 8 wells in the Bohai area since 1996.This parper gives brief introductions and detailed analysis on major problems emerged during the testing process, involves:① discharge fluid of drilling rig;② MFE tools;③ range of pressure recorder;④ encountering resistance in downhole;⑤ inverse circulating valve;⑥ petroleum blow-out;⑦ pipe string design;⑧ prevention of f reezing when testing during winter;⑨ operation on MFE valve;⑩ tools falling into downhole etc.
