METHOD FOR DETERMINING THE OPTIMAL COMPENSATION FOR THE SELECTION OF PRODUCTS AT THE SITE OF THE DEVELOPMENT OF AN OIL FIELD Russian patent published in 2022 - IPC E21B43/12 E21B47/00 

FIELD: products selection compensation determining.

SUBSTANCE: invention relates to a method for determining compensation for the selection of products at the site of the development of an oil field. The method for determining the optimal compensation for product withdrawal at the site of oil field development includes the allocation of a reservoir area with hydrodynamically connected wells, injection of a displacing agent through an injection well and withdrawal of production through production wells, changing the volumes of injection of a displacing agent during development. Displacement agent injection pressure is measured, a model curve of displacement agent injection pressure change is constructed. The dynamics of changes in the values ​​of the injection pressure of the displacing agent is analyzed from the time of operation/idle time of the injection well. A trend line is superimposed on the model curve of change in the injection pressure of the displacing agent from the time of operation/idle of the injection well, and a horizontal straight line is built according to the maximum pressure value on the pressure drop curve. A trend of changing the trend line of the model curve of changing the injection pressure from a horizontal straight line is revealed and the volume of injection of the displacing agent into the injection well is changed.

EFFECT: increasing the efficiency and reliability of the reservoir pressure maintenance system, preventing a decrease in reservoir pressure without stopping the reacting stock of production wells.
