摘　　要：近年来,低—特低渗油藏已成为国内油气勘探开发的主要目标之一,准确评价此类复杂油藏对油田稳产具有重要意义。通过对西259井区长32特低渗透率油藏的成因机理、四性关系研究。以岩心分析化验资料为依据,采用"岩心刻度测井"的研究思路,重新建立了研究区孔隙度、渗透率、含油饱和度解释模型,制定了测井解释标准并进行了二次解释,满足了该油藏开发的需要,为特低渗透率油藏的研究和开发提供了思路。Recently,very-low-permeability reservoirs have become exploration targets in China,so it is important to precisely evaluate such complicated reservoirs for a stable oil production.This paper analyzes the genesis of Chang-32 very-low-permeability reservoir in Xi-259 Well,based on core observation and chemical assay data,applies ＂core scaling logging＂ to re-establish a model of porosity,permeability and oil saturation,and carries out the second interpretation on logging,which meets the requirements of the reservoir development and provides a reference in studying and developing such very-low-permeability reservoirs.
