JB油区长2油藏二次测井解释应用

Application of secondary logging interpretation in Chang 2 reservoir of JB oil area

JB油区长2油藏为典型低渗透油藏,开发效果与初次解释结果冲突。有必要结合目前的生产动态情况,进行测井二次解释,为研究区下一步开发生产提供依据,二次解释充分利用岩屑录井、取心、薄片析及试油试采资料,并结合生产动态分析,分岩性建立研究区的储层参数和测井解释模型,提高各解释参数精度,为油田精细开发提供依据。

Chang 2 reservoir in JB area is a typical low permeability reservoir,Conflict between development effect and initial interpretation result.It is necessary to combine the current production situation,second interpretation of logging,Provide basis for further development and production of the research area.The second interpretation makes full use of cuttings logging,coring,thin section analysis and production test data.Combined with the analysis of production performance,the logging interpretation model of reservoir parameters suitable for the study area is established according to lithology.Improving the accuracy of logging interpretation parameters in the study area.Improve the basis for the fine development of logging in low permeability reservoir.
