聚合物溶液驱油技术已成为我国提高原油采收率的主要技术之一[1]。聚合物溶液中使用的聚丙烯酰胺简称PAM,由丙烯酰胺单体聚合而成,是一种水溶性线性高分子物质。固体PAM为白色粉末或硼砂状,有吸湿性,吸湿后很黏。易溶于水,其水溶液为接近透明的黏稠液体,不溶于甲醇、乙醇、丙酮、乙醚、脂肪烃和芳香烃[2]。聚丙烯酰胺可用于钻井、采油、水处理等各个领域[3]。但聚丙烯酰胺在手工破袋添加过程中会产生大量的粉尘,对作业工人的身体健康影响较大。为改善聚丙烯酰胺添加时工作场所的卫生状况,保护工人身体健康,同时提高工作效率,某单位设计了自动化的 Polymer solution flooding technology has become one of China’s major technologies to improve oil recovery [1]. Polyacrylamide used in polymer solution, abbreviated as PAM, is polymerized from acrylamide monomer and is a water-soluble linear polymer material. Solid PAM is white powder or borax-like, hygroscopic, very sticky after moisture absorption. Soluble in water, its solution is viscous liquid close to transparent, insoluble in methanol, ethanol, acetone, ether, aliphatic hydrocarbons and aromatic hydrocarbons [2]. Polyacrylamide can be used in drilling, oil recovery, water treatment and other fields [3]. However, polyacrylamide in hand bagging process will produce a lot of dust, the greater impact on the health of workers. In order to improve the sanitary condition of workplace at the time of adding polyacrylamide and protect the health of workers, at the same time, to improve work efficiency, a unit has designed an automatic
