摘要
火山岩储层岩性复杂、孔隙结构多样,给储层岩性识别、评价带来困难。本文以大庆深层火山岩储层为对象,在研究不同流体地层的测井响应的基础上,采用图板法和三孔隙度曲线重叠法定性地识别气层,并用三重孔隙模型定量计算储层的含水饱和度。试气结果与计算得到的结果一致,说明这些方法在识别火山岩流体性质方面是可行的。
The vulcanite reservoir is characterized by complex lithology and variety of pore structure,which brought about difficulty in identifying and evaluating the lithology of volcanite reservoir.Taking deep volcanite reservoir in Daqing Oilfield as object and on the basis of studying the logging response of strata with different fluids,the paper used crossplot and tri-porosity curve overlapping method to qualitatively identify gas-bearing bed and used triple porosity model to quantitatively compute the water sat...
