Abstract
The aim of this sutdy is to research the time dependence of deformations under complex stress conditions arising in the ground formation during the exploitation of oil and gas fields. The experiments were carried out on the IP Mech triaxial independent loading test system on the rocks of the Prirazlomnoye oil field using loading programs simulating the stress state in the near-borehole region with a decrease in pressure in the well. Experimental dependences of deformations on time during step loading are presented. The basic requirements for constructing a model of a stress-strain state taking into account the influence of time effects are discussed.
