Inelastic Deformations of Rocks and their Influence on Development of the Oil and Gas Fields

The article is focused on the inelastic deformations of rocks and their influence on the development of oil and gas deposits. The influence of the relaxation deformation of rocks on the parameters of the reservoir development, such as reservoir pressure, p orosity, and oil saturation has been addressed. The numerical analysis was performed in assumption that the oil - gas deposits are developed as a uniform grid of wells and under conditions when gas - oil interaction is constant. The performed analysis demonstr ates the process of the rock relaxation in regard to the defined specific parameters during the development of the oil - gas deposits. It has been concluded that the rock relaxation has the maximum effect on the oil - gas deposits when the initial reservoir pr essure is the highest.
