Abstract
- In order to improve the dissatisfied oil displacement results of conventional low molecular weight polymers in some thin and poor reservoirs of the Daqing Oilfield in China, two new polymers with low molecular weight are introduced. A series of laboratory experiments were performed to evaluate the performance index and oil displacement results of the novel polymers. The results show that the new polymers have the characteristics of higher viscosity, better salt and shearing resistance, and better solubility than conventional polymers, and the viscoelasticity and shearing resistance of the new polymers increases with a decrease in molecular weight. Bench-scale oil displacement experiments indicate that the oil displacement results of the new polymers are better than those of the conventional polymers with the same molecular weight and the performance will be better with a decrease in molecular weight. Novel polymers have a favorable matching relationship with low-permeability reservoirs that are f...
