安棚地区Ⅳ油组渗透率计算方法研究

Computation of Permeability of Ⅳ Oil Group in Anpeng Area

一般通过实验室岩心柱测定可得到绝对渗透率,但对于大量未取心井段和层位,渗透率的求得必须借助测井信息。以赵凹油田安棚地区Ⅳ油组取心井的分析资料为基础,利用测井资料,建立了渗透率与测井参数的关系图版,然后利用岩心分析渗透率对该方法的计算结果进行检验,相对误差达到了测井分析所要求的精度,较好地解决了安棚地区Ⅳ油组渗透率计算的问题。

Generally,the absolute permeability could be determined by core column testing in the laboratory.But for the most of the wells without coring date,permeability could be obtained from logging information.Based on the coring well analysis of Ⅳ Oil Group in Anpeng Area of Zhaowa Oilfield,logging data were used to establish the correlation chart of permeability and logging parameters.The result was tested by core analysis permeability.Relative error was within the range of logging analysis requirement.The computation problem of permeability of Ⅳ Oil Group in Anpeng Area is well solved.
