Abstract
To ensure efficient separation of oil production wells with a high content of associated petroleum gas, inlet separation units are used, consisting of an inlet separator, which ensures the separation of the main amount of free gas from liquid, an oil and gas separator, in which free gas is finally separated from the liquid, and a separator-drop catcher, designed to prevent entrainment of droplet liquid with gas. When a gas-water-oil mixture with a high water content enters the plant, an oil and gas water separator can be used instead of an oil and gas separator, which makes it possible to carry out a preliminary discharge of water simultaneously with degassing. The article considers the technology of separation and preliminary discharge of water for oils with high gas content and proposes a variant using heating of a partially degassed liquid. Empirical dependences of the minimum height of the liquid column above the oil and gas separator (gas and water separator) depending on the viscosity and density of the liquid are given. A technique for technological calculation of the mutual arrangement of apparatuses has been developed, the possibility of using heat exchangers as part of the installation has been shown.
