一次性高聚物
The primary oilfields have been attaining the high water-containing exploitation period nowadays, and the manner of the oil driven has transferred from water to polymer or ternary compound matter.
近年来,我国主力油田已进入中、高含水开采期,驱油方式已由原来的水驱向聚合物驱和三元复合驱油技术发展。
The high gas permeability of PMSP results primary from substantial gas solubility and diffusivity, which appears to be due to, in turn, to a large excess free volume in the unrelaxed ( Iangmuir) domains of this glassy polymer.
PTMSP的高透气性主要来源于极高的对气体溶解度及高扩散系数,而这是因为在这种玻璃态聚合物中,有大量处于非松弛区域的自由体积。
