Annotation:
The article sets the task of determining the development indicators in the water-pressure regime of oil fields, the rocks of which are subject to nonlinear elastic deformation, taking into account the activity of the aquifer water zone. A system of differential equations has been obtained that allows, in accordance with the continuous movement of the water-oil contact during development, to determine development indicators such as reservoir pressure, porosity, oil saturation, gas factor, and the volume of the oil part of the field. Based on the solution of the obtained system of equations within the framework of the appropriate initial conditions, it is possible to construct an effective system for developing oil fields in the natural water pressure mode with nonlinear elastic deformation of rocks and to implement its controlled operation.
