油气田开发方案优选方法的研究

本文建立了一类优选油气田开发方案的模糊积分评价与灰色局势决策方法。全面地考虑了各种技术、经济指标在整个方案优劣评价中的重要程度,对权重的确定进行了改进,并把所建立的方法应用于某气藏开发方案的优选中。两种方法所得结论均与实际一致,说明灰色系统理论与模糊积分方法都可成功地应用于油气田开发方案的经济评价中。

RESEARCH OF OPTIMIZATION METHOD OF OIL AND GAS FIELD DEVELOPMENT SCHEME

In this paper, fuzzy integral appraisal and grey situation decision have been set up in the optimization of oil and gas field development scheme, we have paid full attention to the satisfaction degrees of various technology and economy targets, and applied this two methods to the economy appraisal of a gas deposit. The results obtained by the two methods are in agreement with the actual ones.
