Consumption of oil products grows in the modern world from year to year. For oil-producing countries export of the production is fundamentals of external economy. At constantly growing the offer the efficiency of oil recovery from oil-bearing layers at the modern, industrially mastered methods for all oil-producing countries is unsatisfactory. On average, the final oil recovery of layers in various countries fluctuates from 25-30 %. Annually interest in methods of increase in oil recovery of layers only increases. On this basis the researches directed to the choice of the most effective technologies of mining actively develop. Under various conditions of a condition of residual stocks, it becomes clear that it is impossible to call a uniform method of increase in oil recovery of layer. Therefore, are at the moment known group of methods influencing layer: gas, thermal, chemical, hydrodynamic methods, group of the combined methods and methods of increase in an output of wells.
