四川盆地西部中二叠统茅口组油气地质条件及勘探潜力OA北大核心CSCDCSTPCD
Petroleum Geology Conditions and Exploration Potential of Middle Permian Maokou Carbonate Rock in Western Part of Sichuan Basin
四川盆地西部中二叠统茅口组为碳酸盐岩浅水缓坡相沉积，高能浅滩亚相颗粒岩发育。茅口组沉积末期，研究区古表生岩溶作用强烈，有利于岩溶储层发育。中二叠统发育栖霞组和茅口组碳酸盐岩、梁山组泥质岩等多套烃源岩，烃源岩厚度大，品质较好；各套烃源岩从中三叠世末起相继达到生烃高峰，资源潜力大。茅口组中上部发育两类储层：裂缝-孔洞型(或裂缝型)储层和白云岩孔隙型储层。钻井及露头剖面揭示茅口组含气性好。高能滩相沉积区与岩溶斜坡带叠合区是茅口组储层发育的有利地区。茅口…查看全部>>
High- energy shoal subfacies grainstone widely develops in Middle Permian Maokou carbonate shallow gentle slope in the western part of Sichuan Basin. Effected by Dongwu uplifted movement, karstic reservoirs developed in this region due to intensive hypergenic karstification at the end of Maokou age. Several sets of thick and good source rocks, such as Middle Permian Qixia and Maokou carbonate rocks, and thick Liangshan mudstone rock, developed during M…查看全部>>
