One of the main problems of the modern oil and gas industry is to increase the degree of extraction of hydrocarbons from fields. As a solution, various methods of enhanced oil recovery are being introduced. One of the promising methods is the vibration impact on the formation by downhole vibration sources, in which the working force on the casing string is transmitted using hydromechanical power elements. During operation of the power element, its elastic chamber experiences a complex stress-strain state under the action of high pressure of the working fluid. To perform calculations of dynamic processes in a load-bearing element and select the optimal design parameters during design, it is necessary to know the dependence of the volumetric modulus of elasticity of an elastic chamber on the acting pressure. The paper describes the experimental technique and the results of determining the bulk modulus of elasticity of an elastic chamber under working deformations. |
