The oil reservoir operation is characterized by periodic emissions of low-pressure gas accumulating in its gas space. In the process of analyzing the characteristics of compressors used in petroleum gas utilization systems, the technical and economic advantages of using jet devices to improve the environmental safety of oil reservoirs have been established. Based on the analysis of pressure, energy and cavitation characteristics, the regularities were established for changing the limiting mode parameters of jet device of the low-pressure petroleum gas utilization system in the gas space of oil reservoirs of the hydrocarbon collection and treatment system. The limit pressure mode corresponds to the zero value of the injection coefficient and is determined by the maximum pressure value created by the jet device. An inverse nonlinear dependence of the maximum relative pressure on the main geometric parameter of the jet device is established. An increase in the main geometric parameter of the jet device causes an increase in the maximum injection coefficient by 62.1%. The optimal operation mode of the jet device takes place when it is operated with maximum values of the efficiency factor. The jet device design, the value of the main geometric parameter of which equals 3, ensures its operation in the optimal mode. The cavitation operation mode of the jet device is characterized by a decrease in pressure at the outlet of the working nozzle of the jet device to the pressure value of saturated vapors of the operation environment. The dependence of the minimum pressure in the flow part of the jet device on the flow rate value of the working flow has an inverse non-linear character. The equality between saturated vapors pressure and current liquid pressure determines the maximum permissible flow rate of the working flow during operation in the cavitation mode
