STUDY OF VOLCANIC RESERVOIRS IN THE EASTERN DEPRESSION OF THE LIAOHE BASIN
-
摘要: 辽河盆地东部凹陷是火山活动最为强烈的地区,也是辽河盆地已发现火山岩油藏最多的地区。火山岩油藏类型有裂缝型、裂缝-孔隙型、风化-淋滤孔缝型等。研究区火山岩夹于巨厚的生油岩之间,或上覆巨厚的生油岩,生油岩具有较好的生油条件;火山岩中原生及次生孔缝发育,储集性能较好,并且可以提供油气运移的良好通道;成藏条件间还具有良好的时空配置关系,因而研究区火山岩具有良好的成藏条件。火山岩油藏在分布上具有以下规律性:水下喷发形成的淬碎熔岩及火山碎屑岩等为有利岩石类型,在靠近主要及次级断层的应力集中部位较有利于油藏的形成,火山锥在地形上常为高部位,有利于油气的聚集和保存。Abstract: Eastern Depression is the area with the most fierce volcanic activity in Tertiary and with the most volcanic reservoirs in Liaohe basin. Reservoirs were formed by fissure, fissure-porosity and weathering-leaching. Volcanic rocks are laid between good oil-source rocks with great thickness, or capped by the source rocks. Primary and secondary porosity and fissure were well developed in some lithofacies in the volcanic rocks, which provided sufficient space for oil migrating and accumulation. Therefore, the volcanic rocks in the area are favourable for hydrocarbon accumulation. Lava of subaquatic eruption and volcanoclastic rocks near the faults, and volcanic cone are suitable for formation and preservation of reservoirs in the area.
