高含水油田储层流动单元定量研究探析

在高含水期，油田没有取心资料的情况下，依据新井测井曲线特征，参照相邻老井的岩心资料，对储层的物性、电性和含油气性进行了重新解释，从而获得了流动单元划分所需的参数，进而对关键井流动单元进行划分。依据对关键井流动单元划分的结果，运用逐步判别程序，确定了非关键井的流动单元判别函数，达到流动单元研究的定量化研究。实践证明，根据这种方法所制定的措施极大地改善了该油田的综合开发效果。

Quantitative Research of Flow Units of High Water-bearing Oilfield

Lacking data of coring during high water-bearing stage, depending on the characteristics of new well-logging, referring to the data of old well core, this paper discusses the mode of lithologic, porosity, and permeability. Then we obtain the parameters we need so that we can classify the flow units in core wells. Governing the results we have gotten, we can use step-by-step discriminant functions to identify non-core well flow units and take quantitative research. It proves that planned projections, according to the fruits of research, can improve greatly the comprehensive exploitation effect of the oilfields.
