secondary oil meaning in Chinese
初级油过滤器
Examples
- Secondary oil filter
机油精滤器 - The inhomogeneous structurral evolution resulted in the charactoristics of early stage pool - forming , serious pool destruction , small range of secondary oil generation , and poorly developed sand bodies and lower hydrocarbon enrichnrent of the south sag of the basin
喜山期，盆地进入挤压阶段，随着第三系沉积厚度的不断加大，侏罗系源岩开始二次生烃，原含油气系统得以活化与重建。 - The author has done some oil displacement experiments on homogeneous core using the polymer solution with the molecule weight of 6 million , 8 million , 12 million after sheared , and done some research on the affection of the same molecular weight and the same viscosity polymer solution on the secondary oil layer displacement characteristics
摘要对经剪切后相对分子质量分别为600 10 ^ 4 、 800 10 ^ 4和1200 10 ^ 4聚合物溶液在均质岩心上进行驱油实验，并对比分析相同相对分子质量、相同黏度的聚合物溶液对二类油层驱油效果的影响。 - 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 % 。
