METHOD FOR PREPARING AND PUMPING INTO WELL MULTI-COMPONENT TECHNOLOGICAL SYSTEMS AND PLANT FOR REALIZATION OF SAID METHOD Russian patent published in 2005 - IPC

FIELD: oil and gas industry.

SUBSTANCE: method includes adjustment of pumping and dosing equipment on basis of amounts of components and their feeding time. Multi-component technological system is forced into well. Adjustment of pumping and dosing equipment is performed by means of frequency converters. Frequencies, set at frequency converter of forcing pump electric engine, at frequency converter of linker-feeding pump electric engine and at frequency converter of powdered polyacrylamide dosing pump electric engine are determined from mathematical formulae. Plant has drift dosage means for powdered polyacrylamide, drift dosage means for powdered components, two ejector mixers, mixing tank, forcing pump, linker tank. Electric engines of forcing pump, linker pump, first and second drift dosage devices are provided with frequency converters. First and second ejector mixers are provided with replaceable nozzles, with diameter 4.5-8.0 mm to provide for 150-250 m³/day plant productiveness.

EFFECT: higher precision.
