EXPERIMENTAL STUDY OF THE TENSION-DEFORMATION STATE OF THE TIGHTENING COMPONENT

Gas lift equipment has a special place in oil extraction.This method has an important place among mechanized methods.This method is used to increase the longevity of the wells, and at the same time, when the productivity of the wells decreases, to increase the pressure at the bottom of the well by supplying gas to the space behind the well, to raise oil to the surface.Gas lift valves are one of the main components of the equipment complex used in wells using the gas lift method.Depending on the characteristics of the wells, it is required to meet complex requirements from the gas lift valves, among which the provision of tightening is one of the important problems.In order to ensure effective tightening in gas lift valves, it is of great importance to choose the construction, dimensions of tightening elements, as well as the criteria of tightening correctly.From this point of view, the solution of scientific-practical problems related to the design and calculation methodology of tighteners that can create reliable tightening in gas lift valves can be considered as one of the actual problems of production and exploitation of modern oil field equipment.
