Basin on a comparison of laboratory results with results obtained by screening modelling, one of the most promising methods was selected – the method of oil displacement by means of the polymer injection.Water intended for the injection is thickened with high molecular weight polymers (e.g. Polyacrylamid or Xantan), which increase the water viscosity and, on the other hand, decrease the water mobility. The concentrations of polymers vary in the range from 250 to 2 000 mg l-1 of water and the required volumes of injected water thickened with polymers achieve values ranging from 25 to 60 % of the volume of total oil saturation of the deposit. The method is used as complementary to the process of water flooding. It is suitable even in cases where other tertiary methods are not expected to be successful. |
