Abstract: During the development of oilfield,the different emphasis and different information in different stages,as well as the complexities of continental reservoirs result in the different stress and precision of description in different stages.Reservoir description can be divided into three stages:the early description in preparative stage,fine description in mature stage and precision description in EOR stages.Each stage differs obviously in the description of structure,formation,sedimentary facies,reservoir and geological model.The paper summarizes main stages of reservoir description.

Key words: reservoir description, development stage, geological model, characteristic

摘要： 在油田开发过程中,由于每个开发阶段的任务不同,所拥有的资料基础不同,加之我国陆相储层的复杂性,造成了不同开发阶段油藏描述所要描述的重点内容和精度的不同,从而形成了油藏描述的阶段性.总体来看油藏描述可划分为开发准备阶段的早期油藏描述、主体开发阶段的(中期)油藏描述和挖潜、提供采收率阶段的精细油藏描述三大阶段.每个阶段在构造、地层、沉积相、储层、地质模型等方面所描述的重点内容和精度要求等都有明显差别.本文给出了每个阶段油藏描述应重点描述的对象和内容,所需要的主要技术和方法以及达到的精度要求等.
