Injection of gas to increase the production of crude oil sources

摘要

The method involves inserting a pipe into a crude oil-containing rock or earth layer, and injecting a technical gas for the purpose of an increased conveying of crude oil from the crude oil-containing rock or earth layer. The gas is introduced as compression waves with a speed that is sufficient to produce a turbulent flow of the gas in channels of the rock or earth layer. The duration of the compression waves is varied and selected between 3 minutes and 3 hours. An initial pressure of the pressure wave amounts to 10 bars higher than a rock pressure in the rock or earth layer.
