Justification of the values of the stressed-deformed state of mountain rocks with improvement of petroleum deposits of deep collectors

To date, an important issue in oil production is the enhanced oil recovery of the field. However, the use of various methods of increasing oil recovery leads to a change in the stress-strain state of rocks. In this regard, when using various methods of increasing oil recovery, it is necessary to actively assess the state of the deposit's rocks in order to prevent negative consequences in the form of subsidence, disruption of communication integrity and seismic activity. The paper deals with the calculation of the stress-strain state of rocks and the construction of forecasts of their values in the development of oil fields. Keywords: enhanced oil recovery, stress-strain state of rocks.
