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。
The heterogeneity of permeability parameters and heterogeneity of sandstone body are selected. The gray theory evaluation method is used to evaluate the multi-factor comprehensive evaluation of S1 + 2 reservoir in Lengjiaye oil field in Liaohe River, which overcomes the influence of human factors in the evaluation process. The S1 + 2 reservoir in Lengjiaye Oilfield of Liaohe River is a gentle slope fan delta deposit. The interior of S1 + 2 strata can be further subdivided into 10 sub-layers. Through analyzing the non-homogeneity of single well in 10 small reservoirs of S1 + Based on the multifactorial evaluation of qualitative gray theory, the reservoir heterogeneity distribution model of 10 sub-layers in Lengjia oilfield of Liaohe River Basin was established, which provided a quantitative geological model for the preparation of the development plan of Lengjia oilfield.
