相关分析在电测深资料解释中的初步应用

PRELIMINARY APPLICATION OF CORRELATION ANALYSIS TO THE DATA INTERPRETATION OF ELECTRICAL SOUNDING

本文介绍了在电测深资料定量解释中,根据参数变量的联系程度,以测深曲线倾角(α)与界面深度(H)为主要变量参数,进行相关分析,建立回归方程,用于定量解释。目的层埋深在一定范围内的ρ测深曲线(如KH,KHK,KHKH),推断解释界面深度比较接近实际,经几个孔点的检验,相对误差在.19％—8.93％以内变化.从而提高了解释精度。

It is introduced in this paper that the correlation analysis is conducted by means of main variable parameters from dip angle (α)of sounding curve and interface depth (H) based on the degree of connection among variable parameters in the process of the data interpretation of electrical sounding to establish regression equation used for the quantitative interpretation.The target stratum′s burial depth is within the limit of the sounding curve(ρ_s) (such as KH,KHK,KHKH) and the depth of interpretation interface more approaching the practical situation is deduced. After checking some drill holes ,it shows that the relative error ranges from 0. 19％ to 8. 93％ ,thereby increasing the accuracy of interpertation.
