Аналіз методів підвищення нафтовилучення на родовищах Прикарпаття

Abstract

The Prykarpatya Deposits which are developed by water flood operation entered into the late stage of development. Therefore there is the problem of development them with the purpose of extraction of remaining oil. For the increase of reservoir recovery on the Prykarpatya deposits such methods of action on a layer were used: cyclic water flood, forced selection of liquid, gas and watergas influence, ousting of oil by hot water and solutions of superficially-active matters. In work the methods of enhanced oil recovery are described on the Prykarpatya deposits and possible directions of extraction of remaining oil are considered.
