Data for: Polymer flooding in high-temperature and high-salinity heterogeneous reservoir by using diutan gum

The research data consists of rheology properties of three biopolymers in high-temperature and high-salinity environment, and the oil displacement experiments in heterogeneity physical model in a high-temperature environment. The micromorphology images consist of the micromorphologies in high-salinity brine and distilled water.本研究数据集包含两类实验数据与配套的微观形貌图像：其一为三类生物聚合物在高温高盐环境下的流变学特性（rheological properties）数据；其二为高温环境下非均质物理模型驱油实验数据。所收录的微观形貌图像涵盖高盐盐水与蒸馏水体系中的微观形貌结构。
