摘要

Problems were discussed relating to the theory, process and engineering equipment of the process of compressor less gas injection to a producing formation at the Astrakhan gas field. The formation of a deep cone of depression was preconditioned by significant size and low-permeable reservoir during the outstripping gas extraction from the field central zone. In this case pressure in extreme wells remains close to an initial one. Under these conditions it becomes possible to by-pass the gas between wells in the gas pipeline at the expense of a difference in the values of wellhead pressure. It is planned to carry out compressor less injection of gas to the central zone with the purpose of both pressure maintenance and decrease of the dew point for hydrocarbon condensate.
