METHOD OF SIMULTANEOUSLY-SEPARATE EXTRACTION OF HYDROCARBONS BY ELECTRO-SUBMERSIBLE PUMP AND UNIT FOR ITS IMPLEMENTATION (VERSIONS)

FIELD: mining engineering. ^ SUBSTANCE: invention relates to recovery technics and process of hydrocarbons and is provided for simultaneous-separate development of several production facilities by wells with electro-submersible pump. Method includes lowering into well on pipe string of electro-submersible pump, and higher of its lifting, - at least one packer for running of disconnected to each other packers of two or more objects. Pipe string with packer is outfitted by bypass system with separator or without it, implemented with ability of communication through it of objects, locating inside or outside of it at least one regulating element or metering device. Additionally on-stream of objects formation fluid is directed to the receiving of operating electro-submersible pump and it is extracted into pipe string through the space, forming between it and bypass system. Additionally at the moment of well surveys arrival of flow of formation fluid to receiving of pump from the object, located over packer, or it is overlapped by means of regulating element, or its parametres are changed by means of regulating element. Method can be implemented by means of installation according to one of versions. Well installation includes electro-submersible pump, lowered into well on pipe string, at least with one packer, located higher the pump receiver. Pipe string with packer is outfitted by bypass system, consisting of at least two, couplings of cross flowing lowered on pipe string and located higher and lower than packer, and at least from one pipeline located inside the pipe string between couplings of cross flowing and isolated from pipe string. Additionally couplings of cross flowing are implemented with eccentric channels, communicated to pipe string and also with radial and flushing holes, forming together with pipeline hydraulic channel of bypass system, providing communication or isolation to each other of spaces over and under packer by means of at least one regulating element, installed in bypass system. ^ EFFECT: it provides effectiveness increase of method by means of ability of calculation and regulation of flow rate of each of operated objects. ^ 31 cl, 56 dwg Изобретение относится к технике и технологии добычи углеводородов и предназначено для одновременно-раздельной разработки нескольких эксплуатационных объектов скважинами с электропогружным насосом.
