摘要
针对渤海BZ28-1油田前期开发在潜山地层钻进过程发生过井漏的情况,川庆钻探工程公司钻采工艺技术研究院欠平衡钻井技术服务公司与中海油渤海公司钻井部,在开发兼评价井BZ28-1-N8井的目的层位奥陶系地层首次在152.4mm井眼成功实施了欠平衡压力控制钻井,解决了在潜山构造奥陶系钻进过程中的钻井液漏失问题,同时及时、准确地发现和保护了油气层,取得了良好的效果。
Based on the circulation loss during deep drilling under Qianshan layer for prior-period development of Bohai BZ28-1 oil field, BZ28-1-N8 well was applied successfully underbalanced pressure control drilling technology in 152.4 mm well bore in Ordovician formation at first time. It solved the circulation loss during drilling in Ordovician layer, and found out and protected oil-gas layer directly and exactly. This technology brought a better effect.
