贵州省煤层气与页岩气共探共采的地质优选

通过分析贵州省煤层气与页岩气的开发现状及资源分布特点认为,优选煤层气与页岩气共探共采的有利区域,应以六盘水煤田和织纳煤田的二叠系龙潭组为研究对象。依据龙潭组煤层气和页岩气成藏、保存及开发条件,认为六盘水煤田东部的晴隆向斜和织纳煤田北部的沙包-乐治-三塘向斜群,具有优越的煤层气和页岩气综合开发条件,可作为贵州省煤层气与页岩气共探共采的理想区域。文中还初步探讨了煤层气与页岩气共探共采的开发模式及存在的技术难点。

Geological optimization of coalbed methane and shale gas co-exploration and concurrent production in Guizhou Province

By summarizing the deve4opment status and resources distribution of CBM （eoalbed methane） anti shale gas in Guizhou Province, it is considered that the favorable area optimization of coalbed methane and shale gas co-exploration and concunreut production in Guizhou Province should take Upper Permian Longtan Formation of Liupanshui Coaffield and Zhina Coalfield as the researeh ohjects. Based on the accumulation, preservation and development conditions of the CBM and tile shale gas in lx）ngtan Formation, it is thought that tile favorable exploration area of co-exploration and concurrent production in Guizhou Province arc Qinglong syncline in east part of Liupanshui Coalfield and Shabao-Lezhi-Santang syncline gruups in north part of Zhiua Coalfield, which have superior development conditions of CBM and shale gas and can act as the ideal area of coalbed methane and shale gas co- expluration and toner,trent production in Guizhou Province. In tile end, tiffs paper discusses the deve4opment models and the technical difficuhies of co-exploration and eoneun＇ent production for CBM and shale gas.
