大巴山-米苍山前缘地区油气主控因素及勘探有利区分析

摘要

Through analyzing relations between the discovered reservoirs and local structures ,favorable sedimentary fa-cies zones ,the distribution of faults and fractures ,in combination with reservoir physical property ,sealing ability and thick-ness of cap rocks,key factors of reservoir -forming,logging data,it was studied on the reservoir forming conditions and main factors controlling hydrocarbon accumulation in the front of Daba -Michang mountain .Research results show that the favorable sedimentary facies belts , development zones of faults and fractures , and overlapping area in the high part of a structure are the most favorable targets for the further exploration of the area .%通过对已发现油气与局部构造、有利沉积相带、断裂分布等关系的分析，结合储层物性、盖层厚度、封闭能力、成藏要素及录井资料统计，开展了大巴山-米苍山前缘地区成藏条件及其与油气富集主控因素研究，指出该地区下步勘探的有利方向，即有利沉积相带、断裂及裂缝发育带和构造高部位叠置区是该区油气最富集的地区。
