新安煤田新义井田深部勘查区二_1煤煤层气地质特征
|
摘要
基于新义井田深部勘查区煤田地质勘查成果,分析了该区构造和二_1煤层展布特征,研究了二_1煤储层特征、煤层气含量及其分布规律、煤层气赋存条件。研究认为,勘查区二_1煤变质程度高,有利于煤层气的生成;煤储层孔隙度较高、围岩封闭性好,有利于煤层气赋存;煤体结构遭到严重破坏不利于煤层气运移;属正常压力、低渗煤储层。煤层气含量与埋深呈正相关趋势,DF_1断层为煤层气逸散通道。
Based on the results of coalfield geological exploration in the deep exploration area of Xinyi Mine Field,the structure of the exploration area and the distribution characteristics of Ⅱ_1 coal seam were analyzed,and the characteristics of Ⅱ_1 coal reservoir,the content and distribution of coalbed methane,and the occurrence conditions of coalbed methane were studied.It was considered that the high degree of metamorphism of Ⅱ_1 coal in exploration area was beneficial to the formation of CBM;the high porosity of coal reservoir and good sealing of surrounding rock were beneficial to the occurrence of CBM;the serious destruction of coal structure was not conducive to the migration of CBM;it belongs to normal pressure and low permeability coal reservoir.There was a positive correlation between CBM content and burial depth,and DF_1 fault was a CBM escape channel.
