摘要
随着世界对油气资源的需求不断增加,火山岩(一般指火山熔岩)油气藏的勘探和开发逐步成为油气储量、产量增长的新亮点。岩性识别既是测井储层评价的基础,也是火山岩储层研究中的一个重要环节。本文概括了火山熔岩的岩石特征及测井响应特征,并对目前火山岩岩性识别方法进行总结分析,得出利用常规测井资料交会图法识别岩性的可行性。识别结果与实际情况基本吻合。
With the continuously increasing demand for hydrocarbon resources in the world, the exploration and development of volcanic rock （which generally refers to volcanic lava） reservoir has become the new bright spot for increasing oil reserves and production. Lithology identification is not only the base of logging reservoir evaluation, but also an important step in the research of volcanic rock reservoir. The characteristics of lava rock and log response characteristics of volcanic rock are summarized, the current methods of the identification of the lava are also analyzed here. and it is concluded that the cross plot technology by conventional logging data applied to identify lithology is feasible. The results of identification are proved to be fit with those of reality.
