METHOD FOR DEVELOPMENT OF HYDROCARBONS WITH ASSOCIATED OCCURRENCE AND HYDROMINERAL RAW MATERIAL OF MULTILAYER FIELD Russian patent published in 2014 - IPC E21B43/14 

FIELD: oil and gas industry.

SUBSTANCE: method includes allocation of production facilities, development of the grid of producers and injectors, drilling of wells or selection from available well stock, production of hydrocarbons and injection of a displacement agent to the injection wells. According to the invention producers are used for combined operation of at least two producer facilities by one production tubing using a jet device for lifting of fluids from the two facilities through a flow string and for creating depression to the low-pressure facility due to energy of full flow rate of fluid from the high-pressure facility, and this fluid serves as a working agent for a jet pump at least up to the position level of the first gas lift valve. Injectors are used for volume-adjustable borehole fluid bypass from the high-pressure formation to the low-pressure one. At that at borehole fluid bypass from the high-pressure formation to the low-pressure one through injectors and producers depression is adjusted additionally in the low-pressure formation between the injectors and producers thus ensuring the rate, which washes retrograde condensate off from the enclosing rock pores in the low-pressure formation.

EFFECT: improvement of final condensate recovery from the high-yield formation due to increase of filtration rate of the displacing agent, involvement of trapped gas areas into development process.
