摘要： 火山岩油藏在我国油气田勘探中屡见不鲜,是对砂岩油藏和碳酸盐岩油藏的有益补充。综合运用地质、钻井、测井和地震等方法, 对惠民凹陷中央隆起带临9-临13 地区的辉绿岩侵入体进行了识别, 查明了其分布规律, 着重分析了辉绿岩油藏的形成条件, 认为临商断裂带的展布控制了辉绿岩体的形成与分布, 断裂带在活动期改善了辉绿岩的储集性能, 在成藏期是油气进入火山岩储集层的重要通道, 活动停止期对油气藏起到了封堵作用。

Abstract: The volcanic rock reservoirs commonly occurred in domestic oil-gas exploration are significant complement of sandstone and carbonate reservoirs. According to the comprehensive information of geology, drill sample, well logging and seism, etc., the intrusive body of diabase in the area of Lin-9-Lin-3 in central uplift of Huimin sag is identified, its distribution pattern is found out and the condition of the diabase reservoir formation is analyzed in detail. The result shows that the formation and distribution of the diabase body are controlled by the occurrence of Linshang fault zone; the quality of diabase reservoir is improved during the active period of the fault. The fault zone acts as main pathway for oil-gas migrating into the volcanic reservoirs during the period of hydrocarbon accumulation and plays an important part in sealing the oil-gas reservoir during the ending period of active fault.

Key words: Huimin sag, uplift, diabase, reservoir, fault zone
