【摘要】：稠油粘度高、流動性差,嚴重影響到稠油的開采和集輸。因此稠油降粘技術在稠油開采和集輸過程中廣泛采用,油溶性降粘劑的開發(fā)及在稠油集輸過程中的應用是當前的重要研究方向之一。 論文合成了N-苯基馬來酰亞胺、N-芐基馬來酰亞胺和N-對羥基苯基馬來酰亞胺三種有機物,并將這三種N-芳基取代馬來酰亞胺分別與甲基丙烯酸十八酯和丙烯酰胺進行三元共聚,合成了三種油溶性降粘劑,通過紅外光譜和核磁氫譜對單體及聚合物進行了結構表征。 三種降粘劑中N-芐基馬來酰亞胺/甲基丙烯酸十八酯/丙烯酰胺三元共聚物油溶性降粘劑對新疆風城114#稠油的降粘效果較好,通過正交實驗及單因素實驗確定了該降粘劑的聚合反應條件為：n(甲基丙烯酸十八酯)：n(N-芐基馬來酰亞胺)：n(丙烯酰胺)=10：4：3,引發(fā)劑(AIBN)加量為單體總質量的1%,反應溫度為85℃,反應時間為5h。選取柴油作為降粘劑溶劑,在降粘劑加量為1000mg/L,稠油溫度為50℃的條件下,降粘率可達36.1%。將該降粘劑與表面活性劑十二烷基苯磺酸鈉按質量比為1：2復配時,可將降粘率提升到43.3%。 最后,對油溶性降粘劑降粘機理進行了初步探究,通過對照加劑前后膠質和瀝青質的紅外譜圖、電鏡照片以及紫外可見分光光度計測定降粘劑對瀝青質的分散效率,表明降粘劑能夠減弱膠質、瀝青質分子之間的氫鍵,進而削弱了它們之間的聚集作用,使瀝青質聚集體得到明顯的分散,稠油形態(tài)變得相對疏松,且在降粘劑分子中引入具有拆分作用的苯環(huán)可以提高降粘劑分散瀝青質的效率,進而降低稠油粘度。
[Abstract]:Heavy oil has high viscosity and poor fluidity, which seriously affects the recovery and gathering of heavy oil. Therefore, viscous oil viscosity reduction technology is widely used in heavy oil recovery and gathering and transportation process. The development of oil-soluble viscosity reducer and its application in heavy oil gathering and transportation process is one of the important research directions at present. In this paper, N- phenylmaleimide (N- phenylmaleimide) and N- (p-hydroxyphenyl) maleimide (N- (p-hydroxyphenyl) maleimide) were synthesized, and the three N-arylsubstituted maleimides were copolymerized with octadecyl methacrylate and acrylamide, respectively. Three kinds of oil-soluble viscosity reducers were synthesized and characterized by IR and NMR spectra. The oil-soluble viscosity reducer of N-benzylmaleimide / octadecyl methacrylate / acrylamide terpolymer has a good viscosity reduction effect on the heavy oil in Fengcheng, Xinjiang, and the viscosity reducing agent of N- benzyl Maleimide / octadecyl methacrylate / acrylamide terpolymer is better. The polymerization conditions of the viscosity reducer were determined by orthogonal experiment and single factor experiment. The reaction temperature was 85 鈩，
