FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil industry and can be used during production of fluid for protection against sand phenomenon in wells drilled from the surface. Method involves lowering of casing pipe and it's cementing to the head, lowering of perforated shank or filters to the well in the effective pay section with further lowering of process string to the bottom hole. Pump equipment is lowered parallel to process string. Perforation holes are made in process string prior to lowering to the well at its location place in effective pay section throughout the length of effective pay. Plug is installed on the end of the string. Flushing fluid is pumped to process string in cycles at operating oil producing pump equipment.
EFFECT: reducing the time and costs for underground repair regarding prevention of sand phenomenon.
