| 摘 要： | 采用自行研制的聚丙烯酸高级混合醋作流动性改进剂,在适宜的条件下,可使胜利油田含蜡原油的流动特性(凝点、粘度和屈服值)和石蜡沉积特性得到明显改善。同时研究了实验条件及聚丙烯酸高级混合酯的化学结构对含蜡原油流动特性和石蜡沉积特性的影响,并对聚丙烯酸高级混合酯的作用机理进行了讨论。文中指出,聚丙烯酸高级混合酯的侧链醋基长度必须与原油中石蜡烃长度相适应才能使二者共晶。

| Abstract: | The flow characteristics(pour point, apparent viscosity and yield value) of Shengli wax-bearing crude and the wax deposit characteristics can be improved appreciably by adding a flow improver of poly higher mixed alcohol acrylates(PMHAA)under suitable conditions.The effect of the experimental conditions and the chemical structure of PMHAA on waxy crude flow characteristics and wax deposit characteristics are also studied.A discussion on PMHAA mechanism indicates that the side-chain ester radical in PMHAA must of similar length with the wax hydrocarbon to achieve co-crystallization. |
