火山岩储层研究的关键内容

The Pivotal Characteristics Of Volcanic Rock Reservoir

近年来,火山岩油气藏的勘探开发已经越来越多的被石油勘探工作者所重视,火山岩油气藏因其复杂的岩性及储集空间类型而致使其存在着很大的勘探难度。本文是在前人研究的基础上,结合辽河东部凹陷和松辽盆地的部分资料,总结分析了火山岩储层的岩性岩相类型、储集空间类型、物性特征及火山岩储层评价,进一步分析了其主要的控制影响因素。结果表明构造作用是火山岩储层最主要的有利因素,而充填作用则是主要的不利因素。

Resently, petroleum prospecting workers have paid more and more attentions to volcanic rock hydrocarbon reservoir. Because of complex lithologic character and reservoir space form, volcanic rock hydrocarbon reservoir is hard to explore. This article is based on the study of predecessors and associated with the data of the East Depression in Liaohe and Songliao Basin,in order to analyse lithologic characters, reservoir space form, physical property characters ,volcanic rock reservoir evaluation as well as control factors. The results show that tectonic action is the favorable factor of volcanic rock reservoir and packing action is the unfavorable factor.
