优选油气田开发方案的模糊物元分析

FUZZY MATTER-ELEMENT ANALYSIS FOR OPTIMIZING DEVELOPMENT PROGRAMS OF OIL-GAS FIELD

在物无分析的基础上，结合模糊集合的概念，克服开发方案的制订中许多经济、技术指标的独立性和矛盾性，并综合考虑诸方案中各种指标的优缺点，提出了一种评价和优选油气田开发方案的新方法，称为模糊物无分析法。实例计算表明，该方法优选结果与其它方法一致，且与现场实际相吻合。该方法现场应用简便，计算可靠，不失为一种新方法，有一定的参考价值。

Owing to the characteristics that there are many economic and technical indexes which are dependent as well as contradictory to each other in every development program of oil-gas field, it is very difficult to appraise and determine the projects. If the merits and demerits of various sorts of economic and technical indexes among the programs are considered comprehensively in order to evaluate and optimize the development programs of oil-gas field, it is not very easy' Hence, in this paper, based on the matter-element analysis combined with the concepts of fuzzy sets, a new method is proposed for evaluating and optimizing the development programs of oil-gas field, which is called the method of fuzzy matter-element analysis. It shows througb the actual example that the optimal result is agreed with other methods and corresponded to practice. This method is simPle and convenient to be applied at work site and its calculation is reliable, so that it is a new method and possesses a value to refer.
