据报道,有人研究了在多孔介质中用盐水和缔合聚合物溶液驱替中黏原油(200mPa·s)。在相同的浓度下,缔合聚合物溶液具有比常规聚合物溶液更高的黏度。此项研究是在光学显微镜下刻蚀的二维硅质微观模型上进行的。模型具有与贝雷砂岩相同的孔隙结构。研究结果包括波及状
It has been reported that medium-viscosity crude oil (200 mPa · s) was flooded with a solution of saline and an associative polymer in a porous medium. At the same concentration, the associative polymer solution has a higher viscosity than the conventional polymer solution. The study was performed on a two-dimensional silicon micro-model etched under a light microscope. The model has the same pore structure as Berea sandstone. The results of the study include sporadically
