摘要
新疆三塘湖盆地油气区发育大面积、多套火成岩。通过对常规测井和ECS测井(元素俘获谱测井)资料的分析研究,结合岩石薄片分析和岩屑录井资料,统计出研究区玄武岩、安山岩、凝灰岩、辉绿岩、砂岩及泥岩的测井响应特征(值)。优选出对火成岩岩性反应敏感的物理量和参数进行交会分析,建立一套适合研究区特征的岩性图版,并确定出不同岩性的测井参数范围,从而建立岩性识别标准,为下一步定量计算储集层参数打下基础。
Santanghu Basin is located in Xinjiang, northwest China, where developed huge area and various system of igneous rock formations. The conventional log data and ECS （Elemental Capture Spectroscopy） data are analyzed. Combined with the rock section analysis and sample log data, the log response characteristics of basalt, andesite, tuff, diabase, sandstone and mudstone in the study area are summed up. The physical quantities and parameters sensitive to igneous rock lithology are selected to make crossplot for lithology identification. A set of lithologic chart suitable for this area is set up and the log parameters for different lithologies are determined.
