METHOD OF REGULATING THE DEVELOPMENT OF OIL FIELDS Russian patent published in 2023 - IPC E21B43/30 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to a method for regulating the development of oil fields. A section of the field with hydrodynamically connected wells is taken. The products are taken from producing wells with an analysis of the flow rate. A displacing agent is pumped into injection wells with determination of the outlines of the mutual influence of the wells and the adjustment of the flow rates of the production wells. The flow rates of production wells and the injection of the displacing agent into injection wells are analysed. Permissible deviations of annual oil production in the field are determined. The flow rates of production wells and well operation time are regulated. The volumes are changed and the injection is redistributed into the injection wells until the allowable deviations in the design annual oil production in the field are reached. If the value of tolerances is greater than the actual values, the flow rates of production wells and the operating time are regulated to reduce the inflow. When the value of tolerances is less than the actual values, the operation conditions of the wells is regulated to increase the inflow.

EFFECT: regulation of flow rates of producing wells due to redistribution of injection into injection wells, taking into account the permissible deviations of annual oil production from the accepted design levels for the field.
