Many perspective technologies aimed at production of oil and gas at harsh conditions are not sufficiently developed due to problems with high pressure compressors. The main problem is absence of low-cost compressors and technologies capable of injecting gas without prior treatment. At the same time, there are jet compressors, capable of pumping gas without prior treatment, dehydration and with solids in a stream. However, it is necessary to develop new principles of gas compression with increasing efficiency of the work process in order to reach the jet compressor working pressure of 20 MPa. At Gubkin Russian State University of Oil and Gas laboratories research studies aimed at development of efficient and low-cost ejector systems with implementation of cyclic working process at low frequencies are carried out. Using cyclic working regime allows increasing of efficiency of compressing technologies. Based on unification advantages it is important to develop low-cost compressing technology utilizing produced ejectors, pumps and separation equipment. At the current stage of studies, the main goal is reached: new gas compressing principles using ejector systems are developed. Further studies deal with solving optimization problems and development of mathematical models in order to substitute real experiments with simulations.
