激电测井在城山多金属勘查的应用

Application of IP logging to the exploration of polymetallic ore

激发极化测井是以研究岩矿层、含水层段的电化学性质为基础的一种测井方法,通过测量钻孔内激发极化电位的大小和变化规律,可以研究和划分钻孔地质剖面,确定岩矿层、含水层段的厚度和深度,以及为地面物探和井中物探的资料解释提供岩矿层的电性参数等。本论文主要论述了井中梯度激电测井的基本原理、常规地质实际应用、圆滑滤波探讨、多孔联合的地质推测应用以及相关建议等。以安徽省城山地区为实例并取得了较好的地质效果。

Excitation polarization logging is a kind of logging method based on the study of the electrochemical properties of rock and aquifers. By measuring the magnitude and variation rule of the induced polarization potential in boreholes, we can study and divide the geological section of boreholes, and determine the thickness and depth of rock and aquifer. And providing the electrical parameters of the rock and ore beds for the interpretation of ground geophysical prospecting and geophysical prospecting in well.This paper mainly discusses the basic principle of well well well well well well logging in well, the practical application of conventional geology and the discussion of the smooth filtering,Geological speculates of multi drilling and related suggestions and so on.Taking the city of Anhui Province as an example, good geological effects have been obtained.
