摘要
目前苏里格地区大规模实施三开水平井钻井技术,经过多年的探索已经非常成熟,再进一步缩短三开水平井钻井周期已经非常困难。SXXH井首次采用二开水平井钻井技术,通过钻头选型、井眼轨迹优化、钻具组合优选、钻井液优化等一系列综合提速技术措施,在二开钻进过程中省略中完通井、下套管、侯凝、钻塞等过程,从而有效地缩短了钻井周期。SXXH井钻井施工任务的成功完成,开创了苏里格气田二开水平井钻、完井新技术的纪录。
At present in Sulige Gas Field,three spud horizontal well drilling technology is implemented at large-scale,it is matured after many years of exploration,further shortening the three spud horizontal well drilling cycle is very difficult.The SXXH Well first adopts two spud horizontal well drilling technology,through bit selection,hole trajectory optimization,BHA selection,optimizing drilling fluid and a series of comprehensive acceleration technology measures,in the second spud drilling process,the process drifting well,running casing,waiting for cement curing,drilling out cement and so on are avoided,thus it effectively reduces the drilling cycle.SXXH Well drilling construction is successful completed,it creates a new record for horizontal well drilling,completion.
