摘　　要：储集层的非均质性研究是油藏描述的一个重要的核心内容之一,使人们对比较好储集层所在区域以及空间分布有一个更深层次的认识,从而为油气开发、油气勘探等提供一些可靠的地质资料。为了解决华池油田YT井区延9储层非均质性特征研究中的一些问题,通过测井和岩心资料对储层进行小层划分和韵律特征研究,进而在此基础上进行非均质系数的一些定性解释研究;通过对级差系数、渗透率变异系数、渗透率突进系数等表征参数研究表明,该地区的Y91+2储层的非均质性较强。The study of Reservoir Heterogeneity is one of the important core contents of reservoir description,which makes people have a deeper understanding of the area and spatial distribution of better reservoir,thus,some reliable geological data are provided for oil and gas development and exploration.In order to solve some problems in the study of Heterogeneity of Yan 9 reservoir in the YT well area of the Huachi County Oilfield,the sub-layer division and rhythm characteristics of the reservoir are studied through well logging and core data,based on which some qualitative interpretation studies of the heterogeneity coefficient are carried out.The quantitative studies of the characterization parameters,such as the differential coefficient,the permeability variation coefficient and the permeability breakthrough coefficient,in both the layer and plane,show that the heterogeneity of Y91+2 reservoir is strong in this area.
