FIELD: oil and gas industry.
SUBSTANCE: disclosed is system and method of serial hydraulic fracturing of well shaft with spaced apart intervals along pipe string containing ports for hydraulic fracturing/production. System and method envisage installation of the sand filter units with the help of a fluid medium immediately after the hydraulic fracturing. Above units are installed in the area of each port for hydraulic fracturing/extraction along the pipe string. Each sandwich filter is permeable for oil, but prevents sand flow into the pipe string through ports for hydraulic fracturing, thus prolonging service life of the downhole pump and its components. Preferably, the system and method provide a hydraulic fracturing column which is not cluttered by filters when performing the initial hydraulic fracturing operation, note here that it does not need to be "lifted" from the well for replacement with standard production string with anti-sand filters installed on it. Instead, the anti-poultry filter assemblies are lowered to certain positions in the already installed tubing string immediately after hydraulic fracturing to combat sand ingress during production, which ensures production acceleration and well completion.
EFFECT: proposed system and associated methods of hydraulic fracturing and completion of well, in which by means of fluid medium installation of sand filters for sand control is provided.
