Abstract: As ynthetic appraised of the oil reservior is an important item in the research of oil reservior description,and is a reflection of results of rescrvior description by means of all geological parameters determined by this technology evaluation. An appraised of oil reservoir is a kind of quantitive and scientific evaluation technology. This paper introduces the principle and method of Fisher identification analysis systematically. S1+2S3 in Leng long of Lei Jia area is appraised. The appraised result have become an important basis for exploration and development,field practice has shown that the result is scientific.

Key words: reservoir description, mathematical geology, satistical analysis, reservoir evaluation, reservoir numerical simulation, comprehestsive evaluation

摘要： 油藏综合评价是油藏描述研究的重要内容,是油藏描述成果的集中反映,利用油藏描述技术确定的各项地质参数定量开展油藏综合评价是一种定量化、科学化的评价技术,本文系统介绍Fisher判别分析方法及原理,对冷东-雷家地区沙一、二段和沙三段进行了区块评价,其评价结果已成为制定勘探开发的重要依据,实践证明评价结果是客观的、科学的.
