Application of Electrical Potential Testing Technique in Fracture Detection

Fracturing is an important method to transform lowpermeability oil reservoirs, and it has been widely used in low-permeability oil reservoirs exploitation. Through the fracturing, artificial fractures are formed underground, so as to improve the condition of stratigraphic seepage flow, dredge the stop, and improve oil well productivity. The length and flow conductivity of fracture does not only determine the capability of increasing production and water injection, but also influence the recovery and ultimate recovery of oil reservoir of anhydrous period,
