FIELD: production of liquid and gaseous substances from wells, particularly to treat reservoirs containing oil, gas, water or solutions to clean fluid drainage zone of mud and to create additional cracks in the zone, to clean inner surfaces of pipe or pipe strings inside wells of deposits, rust and scale. ^ SUBSTANCE: method involves filling well or well part with liquid; initiating blast waves in liquid; injecting aqueous clay suspension containing 10-15% of solid phase in productive reservoir opening interval or in pipe string; holding the suspension at rest to develop strength of coagulation gel structure; repeatedly initiating periodical pressure jumps, namely blast waves in suspension so that pressure jump frequency is enough for full coagulation structure recovery between pressure jumps. ^ EFFECT: possibility to perform rock fracturing simultaneously with cleaning of reservoir fluid filtering zone. ^ 3 cl, 1 dwg |
