The article deals with the formation of salt deposits in operational facilities during oil production. Using the example of the analysis of this problem for a number of fields in Russia, Azerbaijan and Kazakhstan, it is shown that this problem is especially pronounced in long-term developed fields. At the same time, it is noted that wells
operated by the ESP belong to the high-risk group. It is noted that microbiological processes further complicate the problem due to the formation of deposits of complex composition. The main reasons for the process of salt deposition in the bottom-hole zone and the failure of a number of geological and technical measures to rehabilitate the filtration and reservoir properties of the formation in the bottom-hole zone are given. In order to increase the efficiency of the geological and technical measures carried out, a technology for processing the bottom-hole zone based on the use of ammonium chloride (NH₄Cl) in combination with surfactants is proposed.
This research paper is devoted to the problem of eliminating salt deposits in wells using the latest composite systems. Salt deposits in wells pose a serious problem for the oil and gas industry, as they can lead to a decrease in well productivity and an increase in operating costs.The paper discusses various methods and technologies aimed at preventing and removing salt deposits. Special attention is paid to innovative compositional systems that can effectively combat this problem. The work includes a review of existing methods, an analysis of their advantages and disadvantages, as well as the study of new approaches to solving this problem.The study provides important
recommendations for oil and gas companies and well drilling specialists, helping them choose the most effective solutions to combat salt deposits and ensure more reliable and productive well operation.
