彰武断陷义县组火山岩油气成藏条件分析

Analysis of Hydrocarbon Accumulation Conditions of Volcanic Reservoirs in Yixian Formation,Zhangwu Fault Depression

针对彰武断陷义县组火山岩基本成藏条件、油气藏特征及成藏控制因素进行了简要分析,认为彰武断陷火山岩成藏主要受油源丰富程度、沟通断层是否发育、构造背景及火山岩储层性能四个因素的影响。

In this article,we analyze the basic geologic conditions for hydrocarbon accumulation in volcanic reservoirs,the oil and gas reservoir characteristics,and the main controlling factors on hydrocarbon accumulation in Yixian formation of Zhangwu fault depression.It is believed that the hydrocarbon accumulation in Zhangwu faulted volcanic reservoirs is mainly affected by the four factors,including the richness of oil sources,the development of communication faults,the tectonic setting,and the volcanic reservoir properties.
