大牛地气田水平井测井施工工艺及应用

Construction Technology of Horizontal Logging Well in Daniudi Gas Field and its Application

增加水平井段长度来提高天然气采收率已成为大牛地气田提高产量的一项重要途径,测井资料的水平井井眼轨迹分析尤其重要,能为后期的采气作业提供依据,同时在水平井钻进过程中,由于钻井液和地层等原因,不可避免的出现井内卡钻事故,当经过泡油、震击还不能有效地解卡时,爆炸切割能有效地解决此类卡钻问题,该项技术已应用于大牛地气田水平井中,并取得了很好的经济效益。

Extending the horizontal section length to raise gas recovery is one of the important methods to increase production in Daniudi gas field. Analyzing the horizontal well path of the logging data is more important, which can provide a basis for gas recovery in the later period. Meanwhile, during the horizontal well drilling, because of the drilling fluid and stratum, drilling pipe sticking accidents will happen unavoidably. However, explosion cutting can effectively solve such problem. Now the technology has been applied to the horizontal wells of Daniudi gas field and good economic benefits have been obtained.
