【摘要】 选择了渗透率非均质参数和砂岩体非均质参数，采用灰色理论的评价分析方法，对辽河冷家油田Ｓ１＋２段储层进行了多因素综合评价，克服了评价过程中人为因素的影响。辽河冷家油田Ｓ１＋２段储层为缓坡型扇三角洲沉积，Ｓ１＋２段地层内部可以进一步划分为１０个小层，通过对冷家油田２４口井Ｓ１＋２段的１０个小层的单井储层非均质性灰色理论多因素评价，建立了辽河冷家油田１０个小层的储层非均质性平面分布模型，为冷家油田开发方案的编制提供了定量地质模型。更多还原

【Abstract】 The parameters of the permeability and sand stone body are used to evaluate the reservoir heterogeneity of S1+2 formation of Lengjia oil field with grey analysis method,and the evaluation is free of conventional concept.The reservoirs of S1+2 formation of this oil field belong to the gentle slope fan delta depositional facies,it can be divided into ten mall unitformations.The two dimension plane models of reservoir heterogeneity of the ten unit-for-mations have been built by the result of grey evaluation of 24 wells of the oil field,it provides a geological model for oil field development.更多还原
