安阳-鹤壁矿区的煤层气资源勘探

Prospecting Coal Bed Methane Resource in Anyang-Hebi Mining Area

安阳-鹤壁矿区有着丰富的煤层气资源,为了更好地指导该区的煤层气勘探开发及煤矿瓦斯灾害治理,以煤田勘探、煤层气勘探资料为基础,对该区煤层气的地质特征进行了系统的探讨。通过对构造背景、煤的储层特征、煤的吸附特征、地应力特征、二1煤层气含气量等的分析,指出含气量分布特征及其控制因素。并在此基础上预测了该区深部二1煤层煤层气含气量,评价了煤层气资源开发潜力。研究结果表明该区二1煤层气含量和渗透性较高,煤层气资源较为富集,煤层气资源量达1 132.98亿m3,具有较好的煤层气开发潜力,区内存在3个较有利于煤层气地面开发的区块,其中彰武伦掌-鲁仙-铜冶可作为首选开发区块。

There was rich coal bed methane on Anyang Hebi Mining Area. In order to well guide the exploration and development of the coal bed methane and the mine gas disaster control in the area and base on the information of the coalfield exploration and coal bed methane exploration, a systematic discussion were conducted on the geological features of the coal bed methane in the area. With the analysis on the geological structure background, coal reservoir features, coal adsorption features, earth stress features, B1 coal bed methane content and others, the paper provided the distribution features and control factors of the methane contents. Base on the circumstances the paper predicted the coal bed methane content of the B1 seam in this block and evaluated the development potential of the coal bed methane resources. The study results showed that there were high coal bed methane content in B1 seam of the block, high permeability, rich coal bed methane resources, coal bed methane resources up to 113. 298 billion m^3 and good development potential of the coal bed methane. There were 3 favorable coal bed methane development areas in the block area and the Zhangwu Luenzhang-Luxian-Tongzhi area could be the first selected development area.
