摘要
三塘湖盆地石炭系水下火山岩主要发育于哈尔加乌组,火山岩蚀变影响储层物性及测井响应特征,原有火山岩解释模型极大地制约测井解释精度。基于石炭系哈尔加乌组的岩心数据明确火山岩蚀变的岩性、物性、孔隙结构和测井响应特征,分析火山岩蚀变的影响因素,实现火山岩蚀变指数的测井定量表征,构建蚀变程度的定量划分表征模型,为深入认识和评价火山岩蚀变规律奠定基础。
The carboniferous underwater volcanic rocks of the Santanghu basin are mainly developed in the Harjiawu formation.The volcanic rock alteration affects the reservoir physical properties and logging response characteristics,which greatly restricts the accuracy of log interpretation by old volcanic rock interpretation method.Based on the core data,the lithology,physical properties,pore structure and logging response characteristics of volcanic rock alteration are clarified.The influencing factors of volcanic rock alteration are analyzed.Logging quantitative characterization of volcanic rock alteration index is realized,the degree of alteration is constructed.Quantitative division and characterization,laid the foundation for deep understanding and evaluation of volcanic rock alteration laws.
