摘要
分析了主成分分析法应用于油气田开发方案评价的应用条件，指出了导致不合理的负加权系数出现的原因，最后利用主成分分析思想扩展了这一方法，通过给出权重系数并附加一定的约束条件，建立了综合的数学模型，实现了方案的客观优选。通过实际应用有如下认识：油气田开发方案优选是一个有限方案的多目标问题，方法很多，但不一定都很成熟，建议用多种方法进行综合评判，最后通过比较得出最优方案；应用主成分分析法作油气田开发方案优选时，须注意应用条件，且方案的数目必须大于指标数目，如果在加权系数中出现负数，则不能用该方法。
The application conditions of the principal component analysis method for evaluating oil and gas field development projects are analyzed and the reasons leading to the appearance of the unreasonable negative weighting coefficient are pointed out.By use of the principle of the principal component analysis,such a method is widened and through attaching a certain constraints to the weighting coefficient,a comprehensive mathematical model is set up and the objective optimization of the projects may be realized.Through practical application,the following knowledge is obtaingd:the optimization of oil and gas field development projects is a multi objective problem of limited projects,there being many methods which,however,are not quite ripe,therefore it is suggested that a comprehensive evaluation in light of various methods may be adopted,then an optimum project can be got through comparison;while the principal component analysis method is used for the optimization of the oil and gas field development projects,its application conditions must be paid attention to and the number of the projects should be more than that of indexes,and if the negative weighting coefficient appears,this method can’t be used.
