“…At the late stage of oil and gas field development, the need for additional pumping and compressor equipment is increasing due to reduced reservoir pressure. At the same time, the well-known compressor and turbine machines do not yet fully solve such urgent problems, because the operating conditions are complicated by the presence of liquid fractions and solid particles in the flow of the pumped medium [22,23,24,25]. There are known technologies of oil and gas wells operation, where jet pumps and compressors are used for liquid and gas pumping at high content of mechanical impurities, as described in patents [1,2] and papers [3][4][5].…”
