摘要
针对火山岩油气藏储层特点 ,应用模糊数学原理 ,选择反映储层宏观和微观特征的储能丰度、渗透率和孔喉半径中值三个参数 ,在岩心分析、测试资料研究的基础上 ,建立储层评价标准及合理构造隶属函数 ,计算权重并选择合适的模糊合成算子对火山岩储层进行综合评价。基于单井评价结果 ,绘制火山岩储层平面分级图 ,判别有利的储层分布区 ,揭示示各类储层分布规律。
According to the reservoir characteristics of volcanics, 3 parameters of reservoir abundance, permeability and median of porethroatradius, which reflect microscopic and macroscopic characteristics of the reservoir, are selected. On the basis of study on core analysis and test data, reservoir evaluation criteria and reasonable structural subordinate function are established, so as to compute weight, select suitable compositional fuzzy operator, and comprehensively evaluate the volcanics reservoir. With the evaluating result of single well, the plane classified chart of volcanics reservoir is drawn, the beneficial distributing area of reservoir is discriminated and distribution rule of each type of volcanics reservoir is revealed.
