| 中文摘要:在钻井过程中经常发生严重的钻井液漏失，不仅给井下安全带来了巨大的隐患，同时也导致更加复杂的井下事故的发生，严重制约了油田的勘探与开发进度。如何有效地解决漏失问题是一个长期困扰工程界的难题。重点介绍了漏层判定方法和堵漏配方模拟评价方法。对于地层漏失，可以首先通过判定方法确定漏层位置，然后再对堵漏配方进行评价，最终形成理想的堵漏配方和相应的堵漏方案。该方法对于提高堵漏成功率，解决复杂地层重复漏失等技术难题具有一定的指导意义。 |

| Abstract:Lost circulation often happens during drilling process, which is not only a severe trouble for safe drilling, but also leads to more complex problems to seriously restrict the exploration and development of oil field. The decision method of leakage zone and the stimulation evaluation on plugging agent formula are introduced in the paper. For formation leakage, the lost circulation zone should be located first, and then the evaluation is made on the plugging agent formulas to decide an ideal formula and the corresponding plugging plan. The success rate of plugging can be increased by this way. |
