白豹油田B306井区长8_1储层流动单元研究

将白豹油田B306井区长81储层划分为三个小层,对其流动单元进行定量研究。利用所有取心井和开发井的砂厚、孔隙度、渗透率、砂厚与渗透率的乘积、泥质含量、含油饱和度以及流动带指数七个参数数值进行聚类分析,把研究区划分为四类流动单元,即E、G、M、P。经过判别分析和回归分析检验,得出各类流动单元的评判函数和取值范围。结合油田动态生产资料发现,各流动单元物性、含油性、沉积微相与产能具有很好的对应关系。

Research on flow units for Chang 81 reservoir of Bai 306 well area in Baibao oilfield

Chang 81 reservoir of Bai 306 block in Baibao oilfield is divided into three little layers,and the researched on flow units should be studied.According to the log data of thickness,porosity,permeability,the production of thickness and permeability,shale content,FZI and oil saturation,with the method of cluster analysis,the research block have been divided into four types of units E,G,M,P.In order to prvoe the validity of the result,used the regression analysis and discriminant analysis to get the discriminant function of the flow units and the index range of every flow unit.Combined with the dynamic production data of oilfield,the results indicate that the properties,oil-bearing,sedimentary facies of the flow units has the good correlation with its production capacity.This is a good guide to production and development of oilfield.
