石油与天然气定量评价的体积统计法（续）

多元线性回归方法的可靠性如何呢?上述研究者以美国的二叠系盆地为评价对象,对该方法进行验证,所取得的结果是令人满意的,和其它方法所得的结果很接近。

STATISTICAL METHOD OF VOLUMES IN QUANTITATIVE EVALUATION OF OIL AND GAS

The statistical method of volumts is that of evaluation of oil and gas resources in new prospecting area using geological analogy based on the function of oil-gas resousces (Q) on volumes (V) of sedimentary rocks and other variables. Developed in the petroliferous areas that have been thoroughly studied, this method has gone through two developmental stages. First, some simple equations relating Q with V are established, though with less desirable effects owing to oversimplication of geological factors. In second stage, some relationships of Q and many geological parameters are established using linear multiple regression analysis. More satisfactory results are obtained in explaration owing to full consideration of variety of geological factors influencing the petroleum resources. Moreover, we must increase information eontent and reliability of every variable for inproving this method.
