Establishment & Application of a New Screening Method for Polymer Flooding
Abstract
There was no quantitative screening criterion or scoring method for polymer flooding. Each parameter in most screening criterions for polymer flooding only had a boundary value for qualitative evaluation. The paper collected ten screening criterions of polymer flooding in the world. It also analyzed the key parameters in criterions and main influence factors of polymer flooding. The paper drew a key factor distribution pattern according to a percentage function in this paper. Based on the distribution pattern, the paper established a new screening criterion and developed a scoring method for polymer flooding screening. The result of 6 reservoirs evaluated by the new method shows an order for polymer flooding. The higher screening score also indicates better EOR factor of polymer flooding. The new method considers different grading score for each parameter in the new criterion. It is reliable to do quantitative evaluation for polymer flooding.
