摘要
枣园油田孔二段储层为湖底扇和滩坝沉积砂体 .针对该区储层沉积特点 ,选择反映储层宏观和微观特征的储能丰度、渗透率、变异因数、粒度中值和平均喉道半径 5个参数 ,建立了储层评价标准 ,采用模糊理论分析方法 ,以小层为单元进行了储层综合评价 .根据综合评价值 ,将本区孔二段储层分为 4类 ,Ⅰ类储层占小层数 13 % ,Ⅱ类储层占小层数5 0 % ,Ⅰ ,Ⅱ类储层分布区为有利储层发育区 .储层分布与沉积微相密切相关 ,Ⅰ ,Ⅱ类储层分布在浊积水道和滩坝砂体中 .
The macroparameters and the microparameters are used in comprehensive evaluation of reservoir of k 2 formation in Zaoyuan oil field with fuzzy analysis method, and the evaluation is free. The reservoirs of k 2 formation of this oil field belong to the depositional facies of the sublacustrine fan and the banklacustrine and barlacustrine, thus it can be divided into eight small unit\|formations. The distribution pattern of the reservoir in the eight unit\|formation has been built by the result in fuzzy evalution in 8 wells of the oil field,therefore it provides a geological model for the oil field development.
