摘要: 基于鸡西矿区梨树井田煤层气勘探开发试验的成功实施,从地形条件、地质条件、技术条件、经济效益等方面分析了不同煤层气开发方式在梨树井田的适应性,以期对该区后续规模化地面煤层气开发有所裨益。结果表明,就单因素分析,从梨树井田的地形条件看,选用丛式井、水平井、U型井及羽状井较为适宜;从梨树井田的地质条件看,采用地面垂直井及丛式井较为适宜;从技术工艺方面看,不宜采用水平井、羽状井、U型井的开发方式;从经济效益方面看,采用丛式井更具经济性。综合分析认为,丛式井是鸡西矿区梨树井田大规模开发煤层气的首选开发方式。

Abstract: Based on the successful implementation of coal bed methane(CBM) exploration and development experiment in Lishu coal field of Jixi mining field, the paper studies adaptability of various development methods for CBM development in Lishu coal field, from terrain, geology, technology and economic benefits, aiming at offering references for commercially developing CBM. It is appropriate to select cluster wells, horizontal wells, Utype wells and pinnate horizontal wells in terrain, vertical wells and cluster wells in geology, and not horizontal wells, pinnate horizontal wells and Utype wells in technology, cluster wells in economic benefits. This paper concludes that cluster wells are the preferred method in developing CMB in Lishu coal field of Jixi mining field at a large scale.

Key words: coal bed methane, geology, cluster well, adaptability, Lishu coal field
