The article describes a model laboratory installation for conducting studies of hydrodynamic parameters, testing of gel pistons, additives and inhibitors, studies of external and internal corrosion of pipe steel, operation of the electrochemical protection (ECP) system, soil composition and properties. A feature of the installation is its multitasking with a wide range of simultaneous and separate studies, simulating the technology of pipeline transport. The degree of influence of additives on rheological parameters or corrosion inhibitors, the assessment of internal corrosion is carried out in the test medium - oil / oil mixture / water / oil-water mixture. Studies of the activity of external corrosion on the pipeline are carried out by selecting the parameters of the ECP system and the state and quality of the protective coating on the pipeline section immersed in the ground. In this case, it is possible to use soils from various sections of pipelines with different corrosive activity, as well as changes in their physical and chemical properties - humidity, salt content. Preliminary data on the influence of soil moisture on its electrical resistivity and metal corrosion rate are presented, the results of which correlate with field studies.Further research will make it possible to reproduce conditions close to real during the transportation of oil and water in order to assess and determine the optimal modes of transportation and technologies for protecting pipelines from corrosion in order to achieve optimal technical and economic indicators for production.
