摘要
长庆靖边储气库随着规模化开发逐渐暴露出钻井中存在的难点,严重影响了储气库的生产运行。为此着重分析了储气库钻井中井眼轨迹控制、311.2 mm井眼侧钻、煤层碳质泥页岩钻井、井眼净化、215.9 mm水平段钻井等关键钻井技术,为储气库的持续开发奠定一定的钻井技术基础。
Along with a large-scale development of Jinbian gas storage, Changqing oilfield,there are more and more difficulties occurring in a drilling, further affecting severely its operation.So, some key technologies have been developed, including well trajectory control, sidetracking with Φ311.2 mm wellbore, drilling carbonaceous mudstones in a coal seam, borehole cleaning,horizontal-section drilling with Φ215.9 mm wellbore. These technologies can provide a certain foundation for a sustainable development of Jinbian gas storage.
