摘要
XL3-3井与XL3-4井是一对水平连通井,由于井眼堵塞而不能循环开采。采用套管开窗技术在XL3-3井实施开窗侧钻,再定向造斜,最终与XL3-4井连通。施工中运用了套管开窗侧钻技术,不但使“死井”复活,而且提高了对井产能和采收率,具有广阔的应用前景。
A pair of horizontally communicated wells,Well XL3-3 and Well XL3-4 can not be exploited circularly due to borehole plugging.Casing window-opening lateral drilling technology is adopted in Well XL3- 3.Then with directional inclination, the well is finally communicated with well XL3-4.Adoption of casing win- dow-opening lateral drilling technology in construction has not only revived th ＂dead well＂but also enhanced capacity and recoverT ratio of hutted well,which enjoys wide application prospect.
