摘要: 采用“权重”评价法对东濮凹陷卫城81断块沙四段第二砂层组进行了储层评价。首先选择参与储层综合评价的参数—有效厚度、孔隙度、渗透率、含油饱和度及泥质含量等,然后按极大值标准化法,计算单项参数的评价分数,接下来,在确定各类参数的权系数的基础上,计算各小层综合权衡评价分数,最后,确定储层的类别。评价结果:Ⅰ类油层组有沙四段第二砂层组第五小层,Ⅱ类油层组有沙四段第二砂层组第一、二、三和四小层。同时,采用容积法对卫城81断块沙四段第二砂层组进行了储量计算,为下一步开发方案的调整奠定了基础。

Abstract: The weighting method is taken to conduct the reservoir appraisement of the second sand bodies of the fourth member of Shahejie formation of fault block 81 in Dongpu depression.First, to choose effective thickness, porosity, permeability, oil saturation and shale content as the appraisal parameters; Then to normalize the parameters according to the maximum value;
Next to calculate the comprehensive appraisal point according to the individual appraisal point and its relevant weight coefficient; Last to classify the reservoir. The appraisal results are as follows: Type I: the fifth sand body of the second sand bodies of the fourth member of Shahejie formation; Type II: the first,second, third and fourth sand body of the second sand bodies of
the fourth member of Shahejie formation. Furthermore, the volumetric method is taken to calculate the oil reserves of the second sand bodies of the fourth member of Shahejie formation of Fault block 81. The research above lays a foundation for the next project setting of oil production.

Key words: Dongpu depression, weighting method, reser-voir appraisement, calculation of reserves
