Study on enrichment zones and enrichment regularity of coalbed methane in Hebei province
摘要
Abstract
In order to study the enrichment zones and enrichment regularity of coalbed methane resources in Hebei Province,through collecting data of coalbed methane,gas data,isothermal adsorption data,and other related data in the mines of multiple mining areas in Hebei province,the paper compared and analyzed coalbed methane resources comprehensively in line with regional geological conditions.The results showed that:Tectonic evolution was the basis on coalbed methane generation and enrichment.Based on the regular of coalbed methane distribution,three enrichment zones were divided.The enrichment zone of the high gas bearing in the eastern Taihang Mountains presented" east high and west low" regular which were controlled by the tectonic and hydraulic action.The magmatism leaded to the characteristics of" south weak and north strong" in east side and "local strong and the overall weak" in west side in the north-south direction.Jinyu and Kaiping enrichment zone of high gas-bearing presented" northwest wing high and southeast wing low" features which were controlled by the tectonic and hydraulic.In the process of tectonic evolution of low gas bearing zones in plain,the effect of uplifting and denudation leaded the thickness of the effective bedrock over the coal seam to be smaller.Although the coal huried depth was large,the over burden thick alluvium was more harmful to the preservation of coalbed methane,gas saturation was lower.The research results have a certain theoretical significance for the exploitation and utilization of coalbed methane resources in Hebei province.关键词
