评价马岭油田木30～木21井区长8储层的宏观不均一性,并分析其与含油性之间关系,为产建有利区预测工作提供依据。在储层沉积微相研究基础上,综合运用岩心观察、测井资料,对研究区长8储层宏观不均一性进行了研究。研究结果表明:研究区长8储层层内、层间储层宏观不均一性均较弱,但层内储层宏观不均一性与含油性关系不大,层间储层宏观不均一性对含油性有一定影响。
The macroscopic inhomogeneity of Chang 8 reservoir in Mu 30 ~ Mu 21 well area in Muling oilfield was evaluated and the relationship between it and oil content was analyzed to provide the basis for the prediction of producing favorable area. Based on the study of reservoir sedimentary microfacies, macroscopic heterogeneity of Chang 8 reservoirs in the study area has been studied synthetically using core observation and logging data. The results show that the macro-heterogeneity of reservoirs in Chang 8 reservoirs is weak, but the macro-heterogeneity of reservoirs is not related to the oil content in reservoirs, and the macro-heterogeneity of interbedded reservoirs Oil has a certain impact.
