Abstract: On the basis of log-geology evaluation and norm,combining with logging data,the method of exact evaluation oil-gas reservoir is presented by using grey theory.The interpretation system has been established on every kinds of micro-computer and micro-computer workstation,and applied in different type wells (including straight well,defleeting well and horizontal well)of more than 100 wells in Huabei,Shengli,Tarim,Erlian and Changqing oil-fiel ds,the application effect is evident.The main processing procedure of method,software,and the practical application example is given in this paper.

Key words: grey theory, evaluation, oil and gas formation, interpretation, system

摘要： 利用测井资料,依据测井地质评价方法和准则,提出利用灰色理论精细评价油气储层的方法,在各类微机和微机工作站上建立起用灰色理论精细评价油气储层的解释系统.通过华北、胜利、塔里木、二连及长庆油田100余口不同类型井(包括直井、斜井和水平井)中的应用,取得了明显的实用效果,文中给出了该方法和软件的主要处理过程和实际应用的例子.
