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。
Increasing the horizontal section length to increase natural gas recovery has become an important way to increase production in Daniudi Gas Field. The horizontal well trajectory analysis of logging data is especially important, which can provide the basis for later gas production. At the same time, Horizontal well drilling process, due to drilling fluid and strata and other reasons, inevitably there will be stuck in the well drilling accident, when after the oil bubble, shock can not effectively solve the card, the explosion can effectively solve such stuck cutting problem This technology has been applied to horizontal wells in Daniudi gas field and has achieved good economic benefits.
