UNIT FOR HYDROPULSE STIMULATION OF PRODUCTIVE STRATA Russian patent published in 1999 - IPC

Abstract RU 2128285 C1

FIELD: oil producing industry. SUBSTANCE: unit includes casing string mounted in well. Assembly of unit includes polyethylene tube located in zone of productive stratum. Cavity of polyethylene tube forms pulse chamber. Electrode discharge (hydropulse device) is lowered into pulse chamber by cable. Since walls of pulse chamber are made from more plastic material (polyethylene tube) as compared with material of casing string, waste consumption of energy is reduced. EFFECT: increased oil recovery factor. 2 cl, 1 dwg
