Abstract
The operation of the most of wells justified that the production of flooded well output is followed with an intensive salt deposition. The formation of salt sediments occurs in various systems of production and collection of output. The paper provides the physical-chemical parameters of produced water from the oil wells in “28 May” OGPD of “Azneft” PU. Therefore, the application of an inhibitor for the injection into the bottomhole zone of producing well with a pump unit is considered reasonable. KD-1 salt inhibitor is injected both into the annular space and bottomhole zone of the reservoir. The implementation of an agent against salt sediments developed in “Oil-Gas Scientific Research Design” Institute is carried out by means of KD-1 salt inhibitor with specific weight of 100 g/t. It is a multi-component synergetic composition meeting all modern requirements to the physical-chemical properties of agents. The increase of oil recovery for each well after the introduction of KD-1 salt inhibitor in “28 May” OGPD approximately comprised 0.5 t/day.
