摘要
以晋城矿区垂直套管完井、U型裸眼井、U型套管压裂井等主要的完井工艺为研究对象,从设计、井身结构、抽采效果及成本等方面对其进行分析,提出当前晋城矿区煤层气井完井工艺须与煤矿矿井建设相结合的建议。
Taking some main well completion technologies used in Jincheng mining area such as vertical casing well completion technology, U-type open hole completion technology and U-type casing fracture well completion technology as the study objects, this paper analyzes the CBM well completion technologies used in Jincheng mining are from aspects of the design, well bore configuration, extraction effect, and cost, etc., and puts forward a suggestion on that the CBM well completion technologies currently used in Jincheng mining area must combine with the construction of the coal mine.
