While producing oil and gas from the fields, creation of cost-effective and efficient compressing technologies for compression and pumping of gas and gas-liquid mixtures is an important objective nowadays. The perspective study of the jet equipment with application of ejectors is described in the article. Compressing equipment gas output pressure might be increased multiply due to implementation of cyclic operation of the ejector. The aim of the conducted studies is to create new principles of gas compression using ejectors. It is showed that due to cyclic operation of the ejector ratio of gas pressure to power pump pressure reaches 1 and that conclusion is proved in laboratory conditions during bench tests of ejector systems. This ratio is between 0,15 and 0,3 for the optimal ejector operation regimes. The assembly of new compressing equipment for providing ejector cyclic operation regime might be completed using serial produced ejectors, pumps and separation elements. Objective of gas compression from 10 to 20 MPa is considered for the cyclic operation of ejector. There is a potential for increase of gas pressure from 20 up to 40 MPa. Considered technical solution might be used both for offshore and onshore oil and gas production. Results of scientific studies and construction works might be used for the creation of gas compressing and gas pumping technologies, for gases like methane, associated gas, nitrogen, carbon dioxide, air, hydrogen or other gas depending on the applied technology.
