摘　　要：通过计算渗透率级差、突进系数、变异系数三项指标来研究储集层的层内非均质性,通过综合分析岩心物性资料及测井解释物性资料,计算平均砂地比、平均渗透率、平均孔隙度、油层钻遇率等指标,探讨层间非均质性。研究得到:研究区具有比较强的层内非均质性,中等略偏强的层间非均质性。结合对层间灰质泥岩隔层稳定性的研究,为层间矛盾的解决和分层注水方案的实施提供了可靠的理论依据。In this paper, the in-layer heterogeneity has been studied by calculating the permeability ratio、variation coefficient of permeability and heterogeneity coefficient of permeability , and through a comprehensive analysis of core data and log interpretation physical property data, the interlayer heterogeneity has been studied by calculating the average sand content、average permeability、average porosity、drilling-en-counter ratio, etc. The study area has a strong in-layer heterogeneity and a moderate to strong interlayer heterogeneity Obtained from the above studies.This theory combined with the research of the interlayer lime mudstone stability provide a reliable theoretical basis for interlayer con-flicts resolution and separate layer water injection program.
