Method for planning production and injection wells

The claimed invention relates to downhole systems for extracting various fluids and, in particular, for extracting fluid from a hydrocarbon-containing formation by hydraulic fracturing. According to the proposed method, a hydraulic fracturing fluid which does not contain a proppant is pumped into a wellbore, thus creating a fracture in a formation, and hydraulic fracturing fluid is introduced into the wellbore in a pulsed mode, said pulsed mode entailing the presence of at least one pulse for the injection of a hydraulic fracturing fluid which contains a proppant and at least one pulse for the injection of a hydraulic fracturing fluid which does not contain a proppant. Also proposed are methods for extracting and pumping a fluid. Also proposed are methods for extracting, pumping and recovering fluids using a hydraulic fracturing method. The proposed method makes it possible to extend the life of a well by reducing the effect of liquid on the walls of a fracture and on proppant clusters.
