曙光—雷家地区特殊储层发育,紧邻陈家、盘山两大生油洼陷,是形成特殊储层油气藏的有利场所。通过对该区特殊储层的形成、分布、油气成藏条件的分析研究,认为古地形、古地貌以及古构造运动控制该区元古界古潜山、古近系火山岩、白云岩、角砾岩等多套特殊储层的形成与分布;不整合面、断层面、沙四、沙三段砂岩以及元古界内幕层状地层为油气向特殊储集层中运移提供多样化的输导路径。其研究成果为该区特殊储层的油气藏勘探提供了方向。
Dawn - The development of special reservoirs in the Leijia area, close to the Chenjia and Panshan oil-producing depressions, is a favorable place for the formation of special reservoir reservoirs. Through the formation and distribution of special reservoirs in this area and the analysis of hydrocarbon accumulation conditions, it is considered that the paleotopography, palaeogeomorphology and Paleo-tectonism control the volcanic rocks in the Proterozoic, the Paleogene volcanic rocks, the dolomites and the breccias Rock and other special reservoirs. The unconformity surface, fault plane, sandstone of Es4, Es4 and the inner-layer stratum of Proterozoic provide diversified transport for oil and gas to migrate into special reservoirs path. The research results provide a direction for oil and gas exploration in special reservoirs in this area.
