油田三次采油中静态混合器的优选

文中选择了三种静态混合器,对它们的降解和混合进行了实验研究,得到了在不同的流速下,三种元件对质量分数为0.5%聚丙烯酰胺溶液的黏度降低率,不同浓度下三种元件压降与雷诺数的关系,以及在工业流速下(0.5m/s) ,压降与元件个数关系式(3^#元件),实际元件数与每组元件个数关系 (3^# 元件)。结果表明:三种混合元件降解和混合性能都达到了生产要求,2^#和3^#元件优于1^#元件。

Choice of static mixers for the third oil extraction

Three types of static mixers were selected.Experiments were carried out on the processes of shear thinning and mixing. In this paper, the effect of different types of mixing elements on the shear thinning of PAM solution with a concentration of 0.5%(mass percentage) and the relations between pressure drop and Re with different mixing elements at different concentrations were obtained. The mixing effects of different mixing elements were investigated. In industrial velocity of flow (0.5m/s), the relation between pressure drop and number of mixing elements(type 3# element)and the relation between factual numbers and each unit numbers of type 3# element were obtained.The result showed that the degree of shear thinning and mixing effects of them reached the industrial requests.Finally,Type 2# and type 3# element were recommended in industray.
