碳酸盐岩储层具有低孔隙度、各向异性和非均质性强等特点,储层级别的准确划分是储层评价研究的重要课题之一.根据碳酸盐岩储层常规测井、试油等资料,分析碳酸盐岩储层测井响应特征,提取对储层物性比较敏感的参数,对每个参数赋予一个权值,再结合试油试采资料,进行综合分析、逻辑推理,得到相应的判别模式,建立了一套储层级别划分方法,使传统的定性解释方法有了定量化的概念,并在实际应用中取得了显著的效果.

The carbonate reservoir is characterized by low porosity, strong anisotropy and heterogeneity. The accurate division of reservoir levels is one of the most important tasks in carbonate reservoir evaluation. Based on conventional logging data and oil testing of carbonate reservoir, analyzed are the logging response characteristics of carbonate reservoir, extracted are the parameters which are sensitive to physical properties of the reservoir. Each sensitive parameter is endowed with a weight value. Combining with oil testing and production test data, the discrimination model is obtained by comprehensive analyses and logic inference. Finally a set of division method of the reservoir levels is set up. The traditional qualitative interpretation has quantitative conception as result of the method. Good results have been obtained in practical log applications.
