| High density electrical method is a very widely used and typical exploration method in geophysics. High density electrical method is a direct current electrical method which provides field source manually, with clear principle, intuitive image, large amount of information and high measurement density. It is a geophysical exploration method with high resolution. This paper combines the practical application of high density electrical method in the karst exploration of shale gas exploration area in Yibin City, southern Sichuan Province With the effect, through changing the parameters of high-density electrical method operation, the paper finally summarizes the optimal high-density electrical method construction parameters of karst exploration in this area, and obtains better geological effect, which provides reliable underground geological information and scientific means for Karst prevention and control. |
