韩城地区煤层气有利区优选
|
摘要
在对韩城地区煤层气井的测井资料和排采数据分析的基础上,研究了煤层厚度、埋深、含气量、孔隙度和渗透率等地质因素对煤层气井产能的影响,利用单因素否决法和灰色关联分析法定量地确定其主控因素,并用模糊综合评价法优选韩城地区煤层气勘探开发有利区。
Based on the logging and drainage data of coalbed methane(CBM) wells in Hancheng area,coal seam thickness, buried depth, gas content, porosity and permeability to CBM well productivity in terms of the impact analysis, single factor analysis and grey correction analysis are established to quantitatively determined the main control factors of CBM wells, fuzzy comprehensive assessment is established to forecast the favorable area for exploration and development of CBM wells in Hancheng city.
