| Abstract: | The discrimination method is firstly applied to evaluate the resource potential of oilfields. A method for evaluating polymer flooding potential based on Fisher discrimination method is proposed, and the corresponding program is also developed. This method has the advantages of fast calculation, full considerating factors and higher calculation reliability. At present, it is difficult to build sample set according to statistical data from the conducted polymer flooding regions. So, a method for generating sample set is presented by comprehensive application of quadrature design, reservoir simulation and economical evaluation methods. The calculation example on the condition of Shengli oilfield verifies the validity of this method. In this example, the rate of correct differentiation reaches 94.0%. The investigative method provided in this paper can be extended to the potential evaluation of other tertiary oil recovery. |
