摘要
涪陵焦石坝区块页岩气资源丰富,是中国第一个页岩气产能建设示范区,而三维定向井是开发页岩气的重要手段。针对焦石坝区块地质条件复杂的客观情况,在二开钻进中使用水力振荡器,降低井下模阻,提高机械钻速,成功解决了三维井托压严重、扭方位工作量大等技术难题,从而加快了礁石坝页岩气产能建设的步伐。
Fuling Jiaoshiba shale gas well is China first shale gas production demonstration area for its rich shale gas in resources,and three-dimensional directional well is an important means of de-velopment of shale gas.Aiming at its complex geological conditions of Jiaoshiba blocks and hy-draulic oscillator was used to reduce downhole mold resistance and improve ROP,which success-fully resolved high three-dimensional backing pressure and large twist azimuth.Thus the produc-tion of Jiaoshiba shale gas construction is sped up in the pace for the early realization of domestic shale gas commercialization foundation.
