摘要
针对鄯善、丘陵油田西山窑油层开发井简化井身结构后,裸眼段长,易漏失层段、易坍塌层段和造浆严重层段同时存在,井下复杂情况频繁的情况,采取突出钻井液造壁性和封堵能力、强化钻井液抑制性和提高润滑性措施的技术路线,并在现场实际应用,收到显著的成效。
Severe hole problems related to hole instability are encountered in Xishanyao shale. They include sloughing shale, poor solid maintenance differential sticking and drlling fluid loss. After using the key methods to improve the performances of inerting, filtration, inhibition and lubrication., serious drilling prodlems are effectively eliminated.
