METHOD OF DEVELOPING OIL DEPOSITS Russian patent published in 1999 - IPC

FIELD: oil producing industry. SUBSTANCE: method includes injection of agents into injection wells. Rows of injection and producing wells are subdivided into sections for organization of change of filtration flows. Rows of injection and producing wells are subdivided into sections so that all wells of one section of injection row operate with maximum volume of injection. All wells of neighboring sections of this row operate with minimum volume of injection. Corresponding to section of injection row with maximum volume of injection is section of producing well row with minimum withdrawal of fluid from well. During the next half-period of cycle, operating conditions of sections of injection and producing rows are changed for opposite. Then, deposit sections are divided by rows of injection wells into closed blocks. Provided in each block is circular or close to it displacement of vectors of filtration flows, first in one direction and then in other. EFFECT: higher oil production and formation oil recovery.
