unsheared meaning in English
未修剪的
Examples
- 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 %
结果表明：未经剪切的聚合物溶液的驱油效果好于经剪切之后的相同相对分子质量的聚合物溶液的驱油效果；对于相同渗透率的岩心，未经剪切的聚合物溶液比经过剪切相同相对分子质量聚合物溶液的注入压力高，而且渗透率越低，相对分子质量越大，差异越大；对于二类油层的各渗透率小层，进行经剪切后聚合物溶液驱油是可行的，聚驱采出程度提高幅度均超过9 . 84 % 。
