ON DETERMINING TEMPERATURE CONDITIONS OF PIPELINES IN OIL-GATHERING SYSTEM

The relevance of the task of examining such characteristics of protective coatings, as sedimentation, corrosion and heat resistance, is demonstrated. Protective coatings must be selected considering the temperature that affects their thermal resistance, so that the costs of carrying out various activities in order to remove organic sediments are reduced. The results of constructing a computer program to determine the temperature change of oil along a specified length of pipeline, for the sake of selecting the optimum type of protective coating to prevent corrosion and formation of organic sediments, are presented. The results of calculating the temperature distribution under given conditions and the length of the pipeline using the computer application “Automated system for calculating thermodynamic flow parameters” developed at the department “Development and operation of oil and gas fields” of the Almetyevsk State Oil Institute show the reasonability of applying protective coatings not only for the purpose of protection from corrosion and formation of organic deposits, but also to reduce the cooling rate of pumped oil products through the pipelines of oil-gathering system. The developed computer program allows to model the temperature conditions of pipelines in order to select the optimal coating system, taking into account the aspects that complicate transportation of oil and oil products
