The article substantiates the necessity of creating a bench for studying the process of AGPD (asphalt-hummin-paraffin deposition) by simulating bottomhole space. The article presents the scheme of the stand operation for well research, and also summarizes the existing problems in the operation of oil wells with high content of asphalt-hummin-paraffin deposits. Methods of prevention and elimination of deposits are considered, explaining the importance of development of a test bench for investigation of downhole space. The main elements of the test bench are described.
