摘　　要：权重确定是综合评价事物客观特性过程中的一个重要难题，长期没有得到有效地解决。本文以川南矿区碳酸盐岩储气层选井选层研究为例，采用灰色关联分析法，在首先指出权重确定意义及应用灰色关联分析法解决该问题可行性的基础上，从理论依据到实现过程阐述了权重确定的原理和方法，为油气藏综合评价中如何确定指标权重提供了一种良好途径。In the comprehensive evaluation of objective specific properties of an object,the weight definition is a puzzling subject of importance,and for a long time no effective solution has been made.Given the example of study on selection of target zones and well locations for the gas-bearing carbonate reservoirs in the south Sichuan petroliferous region,with an approach of grey relationship analysis,it is first pointed out that the weight definition bears significant implications and that the approach of grey relationship analysis can play a viable role in giving a solution to the subject.On this basis,the principles and methods for weight definition are elaborated from the theories to go by and to the processes to carry out.A sound approach is provided for definition of indexes weight in the comprehensive evaluation of hydrocarbon reservoirs.
