苏里格气田59区块盒八段有利砂体厚度预测研究

Prediction and Research on Thickness of the Favorable Sand Body in the8th Member of 59 Block of Sulige Gas Field

本文通过鄂尔多斯盆地苏里格气田59区块盒八上段下段两小层地震属性的提取、预处理及基于粗集理论分析方法的属性优化,运用模式识别储层预测方法对该研究区盒八上段下段两小层分别进行有利砂体厚度预测。并针对储层预测结果进行评价和检验,以期望获得较高精度的储层预测结果。

Through the extraction, preprocessing, optimization based on attribute analysis methods of rough set theory of two small layer of the 8th member of 59 block of Sulige gas field, the thickness of favorable sand body of two small layer of the 8th member was precidcted with the pattern recognization methods in order to obtain the desired results with higher accuracy reservoir prediction.
