unsheared
解釋
未修剪的-
The result indicates that displacement characteristics of unsheared polymer solution is better than the same viscosity polymer solution after sheared, the injection pressure of the unsheared polymer solution is higher than the same viscosity polymer solution after being sheared in the same permeability core, the lower the permeability, the bigger the molecule weight and the bigger the difference, as to the every layer of the secondary oil layer, it is feasible to displace oil with the polymer solution after sheared, and the eor of the polymer flooding can increase more than 9. 84 %
結果表明：未經剪切的聚合物溶液的驅油效果好於經剪切之後的相同相對分子質量的聚合物溶液的驅油效果；對于相同滲透率的巖心，未經剪切的聚合物溶液比經過剪切相同相對分子質量聚合物溶液的注入壓力高，而且滲透率越低，相對分子質量越大，差異越大；對於二類油層的各滲透率小層，進行經剪切后聚合物溶液驅油是可行的，聚驅采出程度提高幅度均超過9 . 84 % 。
