ABSTRACT
In this paper, based on the known physicochemical characteristics and the component composition of the reservoir high-wax oil from D2ef formation of the Kirtaelsky field, a phase behavior model of the studied high-wax oil was developed through the Multiflash Wax module, which allows us to determine the conditions for phase transition of paraffinic hydrocarbons in the gas-liquid mixture. It is established that for the given conditions, the closest to the actual value of the depth of organic deposit formation was obtained through the complex mechanistic model of the vertical multiphase flow OLGAS. The nature of the change in WAT along the wellbore was determined. The changes were highly noticeable when creating a depression in the reservoir and increasing the pressure in the electric submersible pumps (ESP) together with the degassing process of well products. A study focused on the influence of operating parameters of a well equipped with an ESP on conditions leading to the wax formation was conducted. Practical recommendations for the conditions under consideration were obtained.
