COAL-FORMING SETTINGS AND COALBED METHANE OF LONGTAN COAL-BEARING STRATA IN HUNAN-JIANGXI PROVINCES,CHINA

摘要: 湘赣地区龙潭煤系是华南重要的含煤地层之一,煤层气资源丰富,是浅层煤层气开发利用的理想场所。本文分析了湘赣地区龙潭煤系的成煤古地理条件及大地构造环境,在此基础上讨论了龙潭煤系的原始生气能力、储集层及围岩的储气能力,并讨论了印支运动和燕山运动对煤层气富集、分布的影响

Abstract: The longtan coal-bearing strata in Hunan and Jiangxi provinces are the important coal deposits in South Chian,with abundant coalbed methane resources,are the ideal sites tor development and utilization of coalbed methane in shallow part.The coal-bearing paleogeographic conditions and geotectonic environments of Longtan coal-bearing strata in Hunan and Jiangxi provinces are analyxed.On these bases,the original gas-generating capacities,the gas storage capacities of reservoir and surrounding rocks of Longtan coal-bearing strata are discussed,as wdll as the influences of Indosinian and Yanshan movements on the abundance and distribution of coalbed methane.
