MODERN PRACTICE OF SALT DEPOSITION PREVENTING AND REMOVING

Abstract

The problem of salt deposition is a constant companion for the operation of downhole and underground equipment at both the initial and final stages of oil field development. Despite the various reasons for the salt deposition process, its consequences have the same negative impact on the efficiency of oil production. Accumulating in production wells and in oil-gathering communications, deposits of inorganic salts spoil expensive equipment, lead to repair work, and, as a result, to a shortage of oil. The problem of salt deposition in the majority of actively developed oil fields in recent years has become particularly relevant due to the increase in the volume of produced reservoir fluid and the increase in the water content of the products. The article is devoted to the review of modern methods of combating salt deposition in oil production, advantages and disadvantages of key approaches to prevent and remove deposits. It is shown that based on economic efficiency, depending on the conditions and features of the object's operation, different methods of preventing salt formation can be used. The existing methods of preventing salt deposition with classification into technological, physical and chemical are described.
