摘要
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。
Through analyzing relations between the discovered reservoirs and local structures,favorable sedimentary facies zones,the distribution of faults and fractures,in combination with reservoir physical property,sealing ability and thickness 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.
