Abstract:

Salt deposition in oil production occurs in all modes of operation. The presence of inorganic salts on the surface of the working bodies of pumps increases their wear, leads to jamming of the shaft of the electric centrifugal pump (ECP) and the plunger of the deep-groove pump (SHGN), destruction of the impellers. In these conditions, the inter-repair period of the mechanized well stock is significantly reduced. Therefore, it is extremely important to combat salt deposits and prevent their formation. The task of identifying the location and composition of salt deposits is of practical importance – the first step in developing effective methods for their elimination. The duration of removal of the inhibitor largely depends on the amount of adsorption of the salt deposition inhibitor on the surface of the formation rock. At the same time, the greater the adsorption of the inhibitory substance and the slower its desorption from the rock, the longer and more effective it is to prevent the formation of salt deposits. The prevention of salt deposition is achieved by using inhibitors
