川南煤田龙潭组煤系泥页岩气与煤层气组合模式及合采前景分析
|
摘要
文中研究的上二叠统龙潭组煤层及其顶底板泥页岩含气性特征、组合模式及合采对煤系气勘探开发意义重大。为改变煤层气产业低产低效长周期的现状,实现综合效益的目标,将龙潭组作为目标层进行研究;简述了川南煤田龙潭组含气泥页岩与煤层的组合模式,并初步探讨了上述组合模式合探合采的必要性、条件和前景,并提出了开展综合勘探开采的建议。
The study of upper Permian Longtan Formation coal seam and its roof and floor argillutite gas-bearing features,association mode and joint exploitation have great significance on coal measures gas exploration and exploitation. To change CBM industry low yield,low efficiency and long-periodic status quo,realize comprehensive benefit target,have carried out study taking the Longtan Formation as the zone of interest. On the basis of Longtan Formation gas-bearing argillutite in the Southern Sichuan coalfield and coal seam association mode brief introduction,have initially discussed joint exploration and exploitation necessity,condition and prospect of gases under above mentioned association mode,finally suggestions on joint exploration and exploitation put forward.
