摘要
本文利用松辽盆地南部地区扶余油层中有代表性的287个水样,采用判别分析,对数据进行处理,绘出了该区八元判别函数式及 R 等值线图。分析了苯和有机酸各50个水样,确定了含油层水与非含油层水的分界值。利用综合判别值(R)及有机组分含量,可预测有利的含油、气地区。
Abstract
287 water samples were selected from Fuyu reservoir in southern part of Song-liao basin.Their data were processed by means of discriminant analysis.For this part of the basin,8 formulas of discriminant function and isograms of synthetic discriminant value R are given. Benzene and organic acid were determined with 50 water samples respectively, and threshold for waters from reservoir and nonreservoir are confined.
