摘  要：本文利用可溶性淀粉为起始原料，引入常规聚醚进行接枝共聚后制得一种新型的高效原油破乳剂，并将该破乳剂应用于山东胜利油田高含水原油进行破乳。实验室制破乳剂的具体操作步骤为：将烧杯放置于磁力搅拌器上，烧杯中依次加入水、淀粉、甲醇等，然后在搅拌下缓慢加入质子酸，酸加入量为淀粉质量的50%~80%，加完搅拌2—4小时，再将反应物中加入一定量聚醚和甲醇溶剂，加热回流4—8小时，再向反应物中加入配置好的氢氧化钠溶液，至溶液PH值达到7—8，静置3h至溶液透明，即制得该实验室破乳剂。本破乳剂对山东管输原油进行破乳具有工艺简单，操作方便，破乳效果好等特点。85793

Abstract: In this paper, a new type of high efficiency crude oil demulsifier was prepared by graft copolymerization with soluble starch as the starting material, and the demulsifier was applied to high water content crude oil in Shengli Oilfield, Shandong Province。 The specific steps of the laboratory emulsion preparation are: the beaker placed on the magnetic stirrer, the beaker by adding water, starch, methanol, and then slowly add the protonic acid under stirring, the amount of acid added 50% ~ 80 And the mixture was stirred for 2-4 hours。 Then, a certain amount of polyether and methanol solvent were added to the reaction mixture。 The mixture was heated to reflux for 4-8 hours。 A solution of sodium hydroxide was added to the reaction to give the pH value of 7- 8, standing for 3h to solution transparent, that is, the preparation of the laboratory demulsifier。 The demulsifier on the Shandong pipeline crude oil to break the milk with a simple process, easy operation, good demulsification and so on。源Q于W优H尔J论K文M网WwW.youeRw.com 原文+QQ75201.,8766
