平顶山矿区煤层气有利可采区段优选分析
Analysis of Selected Favorable & Workable CBM Blocks in Pingdingshan Mining Area
【摘要】 基于煤层气资源量、资源丰度、煤层气可采资源量、临储压力比、煤层渗透率5个参数,建立煤层气区段开采潜力的分级分类方案,进而结合煤层气地质背景分析,优选出煤层气开采潜力相对较大的井田或区段。结果显示:首一井田为平顶山矿区煤层气地面开采的首选或相对最为有利的地区,13矿为可能有利地区,11矿和10-12-8矿为较为有利的地区,首二井田和1-4-6矿地区可能不利于煤层气的地面开发。
【Abstract】 Based on five parameters,namely,CBM resources,abundance of resources,workable CBM resources,the critical reservoir pressure ratio and permeability of coal seams,a proposal is forwarded for classification of minefields or blocks with workable potentials of CBM.Then,the mine fields,or blocks with relatively high potential of extraction are selected based on geological settings of coalbed methane.The results have indicated that Shouyi mine field is the first chosen zone for surface extraction of coalbed methane,or the most favorable zone in Pingdingshan mining area;and that No.13 mine,the probable favorable zone;and that No.11 and 10-12-8 mines are in fairly favorable zones.Shouer mine field and No.1-4-6 mines are in zones probably unfavorable for surface development of coalbed methane.
