灰色分析法在油气勘探效益评价中的应用

APPLICATION OF GRAY ANALYSIS METHOD IN BENEFIT EVALUATION OF OIL AND GAS EXPLORATION

随着各个油气田勘探难度的不断加大,好的勘探效益不仅能为企业节约不少成本,而且能为油气田的管理者提供决策依据,因此油气田的勘探效益好坏就显得尤为重要,为此,构造了油气勘探效益的指标体系,采用了某油气田连续3年勘探效益指标的原始数据,并对指标进行了归一化处理,以灰色关联度作为评价标准,对连续3年的勘探效益进行综合评价,并且对结果做出了分析,其结果具有分析全面,方法简便,易于计算的特点。

As the exploration of each oil field becomes more and more difficult, good exploration benefit can not only reduce the cost, but also provide policy-making basis for administering authority, therefore, the result of the oil field exploration is very important. This article designed the index system of oil / gas exploration benefit, and carried out normalization treatment for the index system by using the continuous 3 years’ exploration benefit index of some oilfield as basic data. At the same time, the exploration benefit had been valuated by adopting gray correlation degree, and the result was analyzed. The analysis results showed that the index system has the characteristics of comprehensive analysis, convenient method, simple calculation.
