摘要(Abstract)：

二类油层平面、纵向非均性强,井组油层条件差异大,开发过程中参数优化及跟踪调整难度大,需要对油层地质解剖,进行油层井组分类划分。在考虑有效厚度、渗透率、河道砂厚度、河道砂一类连通厚度、高水淹比例、单井控制程度等油层特征参数基础上,建立熵权模糊综合评判模型。通过对井组分类划分实例的计算,结果表明熵权模糊综合评判适用于油田开发过程中的决策。合理地融入了主客观评价,在很大程度上保证了井组分类划分结果的正确性,在二类油层三元复合驱开发调整中具有一定的应用价值。
The second-type oil reservoirs are characterized by the planar and vertical heterogeneity,the reservoir conditions of their well groups are rather different,so the difficulties in the parameter optimization and tracking adjustments are rather serious,it is necessary to analyze the reservoir geology in detail and classify the well groups.On the bases of the effective thickness,permeability,channel sand thickness,the first-type connected thickness of the channel sand,high-watered-out ratio,individual well controlled degree and the other characteristic parameters of the reservoir,the entropy fuzzy comprehensive evaluating model was established. By means of the case calculation of the well group classification and division,the achievements show that the model is suitable for the decisionmaking in the oilfield development process. A reasonable combination of the subjective and objective evaluations has largely ensured the correctness of the well group classification and division results,and furthermore has a certain application value in the development and adjustments of ASP flooding of the second-type oil reservoirs.
