FIELD: oil-and-gas industry. ^ SUBSTANCE: proposed method comprises pumping carbon-based ferromagnetic fluid with ferromagnetic particles and surfactant, fat acid, into formation, acting on the latter by magnetic field and extracting waste products from the well. Kerosene is used as carbon-based fluid. Magnetite is used as ferromagnetic particles. Rapic acid is used as fat acid. Rotating magnetic field is used. ^ EFFECT: higher efficiency of processing well heading, reduced operating costs. ^ 2 cl, 1 tbl, 1 ex |
