摘    要：为了解决红层地区的缺水问题,须探测和利用红层中的地下水.应用电阻率测深法能探测红层中的含水构造,但含水红层和非含水红层的电阻率差异较小,导致用电阻率测深法寻找红层地下水时分辨能力和可靠程度均较低,而采用反射系数(K)法解释电测深ρ_s资料,能提高ρ_s曲线的解释精度,从而提高了电阻率测深法的分辨能力和可靠程度,具有十分明显的地质效果.

Abstract: In order to solve the problem of the water-shortage in red beds, the undreground water must be explored and used. Resistivity sounding method is successfully applied to explore the structure of the underground water in red beds. When the resistance difference between the water-bearing formation and the waterless formation is small, the effectiveness is low using the resistivity sounding method, so the reflection coefficient (K) method is used in the explanation of resistivity soundingρ_s value. This method improves the effectiveness.
