METHOD redevelopment depletion of deposits of natural hydrocarbons

摘要

1 Method redevelopment depleted deposits of natural hydrocarbons, according to which: - preparing reservoir to redevelopment; - create and / or use of at least one injection well for injection into the reservoir, at least one working agent used to produce hydrogen, oxygen , methane homologues, as well as additional recovery of remaining in the formation of natural hydrocarbons - is pumped by at least one worker agent to achieve a given reservoir pressure in the reservoir; - create and / or use of at least one dobyvayusch th wellbore; - begin production of formation fluids after the setpoint reservoir pressure in the reservoir; - from produced formation fluids recovered water, hydrocarbons, hydrogen, oxygen and carbon dioxide, - the extracted water and unreacted carbon dioxide is directed, at least one injection well for reinjection into zalezh.2. The method according to claim 1, wherein the preparation of the depleted deposits to the redevelopment includes collecting the necessary information on the state of deposits, creation of 3D geological and hydrodynamic models, 3D hydrodynamic model adaptation to the development of history, carrying out optimizing predictive calculations with a choice of an optimum variant of further development and determination of optimum operating parameters wells and their arrangement; implementation of the necessary works on reconstruction and repair of fishing holes on the elevated pressures; given formation pressure is determined from the optimum technical and economic parameters of the process using the created modeley.3. A method according to claim 1, characterized in that it is a continuous protsess.4. spo
