Abstract:

The article analyzes the application of non-stationary water flooding at the Lyantorskoye oil, gas and condensate field. This method is based on a periodic change in the conditions of influence on heterogeneous layers, in which a non-stationary distribution of reservoir pressure is created in productive strata and unsteady motion of liquids and gas occurs. It is shown that the technologies of non-stationary waterflooding have a great perspective on the Lyantorskoye field. Methodical methods for determining the effectiveness of non-stationary waterflooding technologies, the tasks of further improving existing technologies of non-stationary water flooding and the creation of new technologies for non-stationary oil recovery are urgent problems of modern oil production, since these technologies today have higher efficiency.
