摘　　要：利用岩心分析资料和测井解释成果,对切16井区E1+2油藏各主要含油小层储层非均质性参数(渗透率变异系数、突进系数、级差和非均质系数)进行了计算,结合昆北地区实际情况,建立了渗透率非均质性参数的评价标准,在此基础上对切16井区各小层层内和层间非均质性进行了评价;同时提出了一种新的研究储层平面非均质性的方法——参数差值平面分布法,对切16井区储层平面非均质性进行了研究;最后,从沉积相和成岩作用方面分析了储层非均质性的主控因素。研究表明,昆北油田切16井区储层非均质性整体上较强,其中,层内非均质性中等,层间和平面非均质性较强,沉积微相和胶结作用是制约本区储层非均质性的主要因素。本次研究可以为昆北油田下一步开发方案的编制提供科学合理的依据。On the basis of core and well log data,the reservoir heterogeneity parameters of the main oilbearing layers in the E1＋2oil pool of the Q16Block is calculated,aiming to set up an evaluation standard of permeability heterogeneity parameters in the study area,carry on a comprehensive evaluation of the reservoir heterogeneity and analyze the main controlling factors of reservoir heterogeneity in the Q16Block of the Kunbei Oilfield.At the same time,a new method,that is called the parameter difference plane distribution method,is proposed to study the plane heterogeneity of reservoirs.The results show that the reservoir heterogeneity is strong in general,and the inner layer heterogeneity is intermediate.However,the interlayer and the plane heterogeneity are relatively strong.Sedimentary facies and cementation are the main controlling factors of reservoir heterogeneity.The studies of reservoir heterogeneity provide the scientific basis for the next project setting of the oil field.
