Title of the articleA method for evaluating the durability of swelling rubber for packers
Abstract.Problem statement. The purpose of the study is to identify the development of the methodology and the conduct on its basis of comparative tests and assess the durability of foreign and Russian elastomer used for the production of packers. Results. The main results of the study are to establish a regime for accelerated testing of water swellable packers (WSP) to determine the change in their properties during aging in a thermo-humid and stress-strain state. Factors of WSP aging in this methodology are: temperature, water and mechanical stress. Accelerated tests were carried out in two stages. The first stage includes accelerated testing of samples in air-dry conditions. The second stage includes bench tests in a water-saturated state. Conclusions. The significance of the results for the construction industry lies in the fact that the elastic properties of the elastomer affect the ability of the packer to contain the hydrostatic pressure of the interstratal water. In addition, the hardness, elasticity, and the value of the residual deformation of the elastomer contribute to its preservation in the event of mechanical stresses that may occur during its installation, delivery or storage. WSP with an elastomer manufactured by Kvart has higher hardness, elasticity and degree of swelling compared to its counterpart, it is less susceptible to destructive processes during thermal aging and retains its properties better, respectively, has a greater durability.
Keywords.water swellable packers (WSP), elastomer, hydrostatic pressure, thermal aging, durability.
