| 摘 要： | 陆梁隆起属于间断继承性古隆起,一直是油气的有利指向区,晚海西期石炭世—早二叠世构造演化基本确立了陆梁隆起的构造格局; 油气多沿继承发育的古凸起、古鼻梁进行油气运聚分配。陆梁隆起存在深浅两套断裂体系,形成深浅两套含油气组合; 深层下组合成藏遵循"源控论",油气多为近源成藏,沿梁富集,受不整合与岩相控制; 中浅层侏罗系与白垩系均为次生油气藏,多沿梁、沿油源断裂聚集,受构造与油源断裂控制。燕山期的构造运动对油气成藏起改造与再分配作用; 喜马拉雅山期构造运动对高成熟的油气起到一定的控制作用; 区域性不整合与火山岩岩体是否发育,是基岩型油气藏形成必备条件; 储层质量影响着油气丰度,控制着油气藏的分布规模与产能高低。今后勘探方向:下组合为夏盐凸起西北环带、石西凸起和滴北凸起; 中组合为石西—莫北凸起结合部、三个泉凸起、英西凹陷、滴南凸起断裂带前缘和滴北凸起断裂带前缘。

| Abstract: | Luliang uplift is a discontinuity successive paleo-uplift,and it is a favorable area for hydrocarbon accumulation.The structural framework of Luliang uplift was formed in the time from the Late Carboniferous to Early Permian.In the late,hydrocarbon occurrence was migrating and accumulating along to paleo-uplift and paleo-nasal profile.There are deep fault systems and shallow fault system,then formed deep and shallow petroleum-bearing combinations.The deep(low)combination followed the "source control theory".The reservoirs formed near source and petroleum accumulated in the uplift.Unconformity and lithofacies are the prime controlling factors for reservoirs formation.In the middle-shallow layers,the Jurassic-Cretaceous reservoirs was distributed in the uplift and in the near of petroleum-migrating-fault,controlled by structural and petroleum-migrating-fault.Yanshanian movement reformed reservoirs and re-accumulated.Himalayan movement controlled the high mature petroleum reservoirs formation.Regional unconformity and volcanic rocks development were the necessary conditions for basement hydrocarbon reservoir formation.Reservoir quality decided the petroliferous abundance and the scale of petroleum accumulation and its productivity.In the future,petroleum exploration direction will be the deep(low)combination which in the northwest surrounding Xiayan uplift; Shixi uplift and Dibei uplift.The hydrocarbon of middle-shallow combination enrich in the joint part between Shixi and Mobei uplift; Sangequan uplift; Yinxi depression; the front of Dinan uplift fault zone; the front of Dibei uplift fault zone. |
