METHOD OF PREPARING AND SUPPLYING HETEROGENEOUS MIXTURES TO FORMATION, AND PLANT FOR METHOD'S IMPLEMENTATION Russian patent published in 2010 - IPC E21B43/16 F04F5/00 

FIELD: oil and gas industry.

SUBSTANCE: in compliance with inventions, heterogeneous mixtures are prepared and supplied to formation through at least one well. Phases of liquid and gas of various pressure are mixed with ejection, and certain volume ratio of phases and control of this ratio is reached. According to inventions, volume ratio of mixed phases is controlled and maintained with determination of their optimum ratio in mode of continuous monitoring with feedback along supply line with well injection capacity coefficient and depending on the depth of its perforation interval, structural geometric dimensions of system of casing pipes and tubing, pressures in liquid and gas phase supply line. At that, ejection at mixing is performed with automatic selection of active and passive phases along feedback line, and hydrodynamic instability of speeds and pressures in flows is created both at ejection and supply of mixture to the formation.

EFFECT: increasing efficiency of the method and enlarging functional capabilities of the device at decrease of material costs.
