碳酸盐岩储层产能预测方法探索

On Productivity Forecast Technique for Carbonate Reservoir

在裂缝性储层中 ,由于储层类型的多样化、非均匀性及各向异性 ,给储层参数计算带来了很多困难。碳酸盐岩储层产能技术是一个受多种因素影响的复杂问题 ,产能预测方法的提出和应用不但对油田开发有重要意义 ,同时也提高了测井解释油水层的效果与评价能力。在综合评分法的理论基础上 ,利用新方法测井资料与常规测井资料结合对碳酸盐岩产能预测技术进行了探索 ,建立了产能预测标准和评价图版 。

In fractured reservoirs,it is very difficult to compute reservoir parameters because of the reservoir’s varieties, heterogeneity and anisotropy. Productivity forecasts of carbonate reservoir are often influenced by various factors. In the light of probability theory, a new productivity forecast technique, namely integrative fracture porosity points system, is worked out for predicting productivity of the carbonate reservoir, based on which established are the productivity forecast standards and evaluation charts for the reservoir. This points system is better used in log interpretations of the Jizhong exploration area in Huabei Oilfield.
