Currently, to produce oil with high content of free gas and solid impurities, gas separators and solid impurity separators of various designs are included in the downhole equipment. These devices, manufactured by different companies, play a significant role in improving the reliability and energy efficiency of the main oil production equipment, i.e. electric-driven blade pumps for oil extraction. Enhancing equipment efficiency and reservoir pressure maintenance technologies is directly linked to the ability to remove solid impurities, residual oil, and associated gas from water. Thus, the efficiency challenges of equipment for separating solid impurities and free gas are characteristic of all the primary technological processes associated with hydrocarbon production. Despite the fact that all these equipment types have technical datasheets, the technical parameters specified in these documents are not always reliable or up to date. This is because the technical characteristics of gas and solid impurity separators are tested on different test benches with different designs and testing methodologies. As a result, end-users often face difficulties in selecting equipment that is suitable for specific operational conditions. To comprehensively assess both existing and prospective designs of gas and solid impurity separators, both in oil production and in water preparation for technological purposes, it is essential to use a generalized, universal bench testing methodology and appropriate test stands. These allow determining the quality indicators of separators, which define the areas of their effective application. To achieve this, bench testing of separators with different designs must be carried out under identical conditions, simulating equipment operation while considering the combined influence of various complicating factors. This article addresses methodological issues of bench testing, ensuring an understanding of the main directions for improving the efficiency of gas and solid impurity separation systems. In particular, it presents the foundations of testing methodologies and the general design scheme of test benches for obtaining operating characteristics of gas separators. Given the need to evaluate the combined influence of various complicating factors on equipment performance, the authors propose a rating system that determines the specific weight of each rating for different operating conditions.
