摘要
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。
Shuguang-Leijia Area, adjacent to Chenjia and Panshan oil-generating sags, is beneficial to form special oil and gas reservoirs. Analysis of reservoir formation and distribution and hydrocarbon accumulation conditions indicates that paleotopography, palaeogeomorphology and palaeotectonic movement dominate the formation and distribution of special reservoirs such as Proterozoic buried hill, Paleogene volcanic rock, dolomite and breccia reservoirs in this area. Various hydrocarbon migration paths towards these special reservoirs involve unconformable surface, fault surface, s4 and s3 sandstones, and Proterozoic interior laminar formation. The result of this study may guide the exploration of special reservoirs in this area.
