| 中文摘要:油基钻井液成本高昂，但对在复杂地层进行的海洋钻井而言，依然具有水基钻井液不可比拟的优势。针对南海西部油气田3个高难度钻井区块钻井过程中遇到的工程难题，给出了相应的油基钻井液体系配方、性能和维护方法；阐述了不同海域含油钻屑的处理方法。钻井实践证明，油基钻井液体系不仅是易坍塌井、高温高压井及老油田超低压调整井钻井作业顺利进行的重要保障，而且具有良好的储层保护性能，有利于油气田的勘探和开发。 |

| Abstract:Although the cost of oil base drilling fluid is extremely high, it always has incomparable advantages compared with water base drilling fluid for the complex formation drilling in offshore. According to the difficulties encountered in 3 complex blocks of an oil and gas field in western South China Sea, corresponding oil base drilling fluid formula, performance and maintenance methods are presented, the processing methods for oily drilling cuttings in different sea areas are discussed. The drilling practice proves that oil base drilling fluid is not only a very important guarantee for smooth drilling operation in easy-collapsed wells, HTHP wells and super-low pore pressure adjustment wells in old oil field, but also has good reservoir protection performance for oilfield exploration and development. |
