摘要/Abstract

摘要：

以三塘湖盆地中、低煤阶煤层含气量和主要气体成分为基础,结合盆地构造、沉积及水文地质特征,对汉水泉凹陷和条湖凹陷煤层甲烷风化带进行了划分,并对库木苏凹陷、马朗凹陷、淖毛湖凹陷和苏鲁克凹陷煤层甲烷风化带进行了预测。结果表明,三塘湖盆地甲烷风化带深度为400~1 000 m. 由于受东北冲断隆起带的影响,三塘湖盆地北部甲烷风化带浅于南部。沉积方面,盆地东部淖毛湖凹陷、马朗凹陷和条湖凹陷深湖—半深湖和辫状河三角洲成煤环境优于盆地西部汉水泉凹陷和库木苏凹陷扇三角洲成煤环境,盆地东部甲烷风化带普遍浅于西部;水文地质方面,条湖凹陷和马朗凹陷中开启性局部滞留水文地质单元形成的甲烷风化带浅于其他凹陷封闭性弱径流水文地质单元的甲烷风化带。初步预测马朗凹陷北部为下一步煤层气勘探开发的优势区块,条湖凹陷北部为下一步煤系气勘探开发的优势区块。

Abstract:

Based on the gas contents and main gas components of the middle and low rank coal seams in the Santanghu basin, and combined with the structure, sedimentation and hydrogeological characteristics of the basin, the methane weathering zones in the coal seams in Hanshuiquan sag and Tiaohu sag are divided, and the methane weathering zones in the coal seams of the Kumusu sag, Malang sag, Naomaohu sag and Suluke sag are predicted. The results show that the methane weathering zones in Santanghu basin are 400-1 000 m deep. The methane weathering zone in the northern part of the basin is shallower than that in the southern part due to the influence of the thrust uplift zone in the northeastern in Santanghu basin. The sedimentary environments of the coal seams of the deep-lake-semi-deep lake facies and the braided river delta facies in Naomaohu sag, Malang sag and Tiaohu sag in the eastern Santanghu basin are better than those of the fan delta facies in Hanshuiquan sag and Kumusu sag in the western Santanghu basin, causing the methane weathering zone in the eastern basin generally shallower than that in the western basin. The methane weathering zones representing open, locally retained hydrogeological units in Tiaohu sag and Malang sag are shallower than those representing close, weak runoff hydrogeological units in other sags. It is preliminarily predicted that the northern Malang sag is the target area for further coalbed methane exploration and development, and the northern Tiaohu sag is the target area for exploration and development of the coal measure gas.

Key words: Santanghu basin, Hanshuiquan sag, Tiaohu sag, Middle-Lower Jurassic, methane weathering zone, coalbed methane, low rank coal
