摘要
在油田开发效果评价中,权重具有举足轻重的地位。关于权重的确定方法有数十种之多,从主观角度把对指标间的定性认识定量化提出应用层次分析法来计算权重,从客观角度根据各个开发指标反映的信息重叠程度和信息分辨能力,提出分别利用复相关系数和变异系数的方法计算权重,最后利用数学方法处理得到综合权重,该方法避免了单一方法的不足和缺陷,具有较高的借鉴价值和良好的应用前景。
The weights had a pivotal position in the comprehensive evaluation of multiple indexes.The right number of methods to identify the weight as many as dozens,whereas from a subjective angle put on the indicators Qualitative inter-Know propose the application of quantitative analytic hierarchy process to calculate the weight,from an objective point of view according to the development of an indicator reflecting the overlap degree of information and the distinguish ability to information,separately proposed the use of multiple correlation coefficient and coefficient of variation calculated weight,finally the use of mathematical methods of treatment to be integrated weights,the method has a single method to avoid the shortcomings and defects of high reference value and a good application prospects.The weight of each index was determined employed of the multiple-correlation coefficient method and coefficient of variation method,which avoided the limitation of single method.
