摘要/Abstract

摘要： 以有机胺为起始剂、环氧乙烷和环氧丙烷为单体、氢氧化钾为催化剂，合成嵌段聚醚型破乳剂单剂TA162824，用TA162824分别与助剂TEAC和DMA按不同比例进行复配，用瓶试法分别对陕北油田的河庄坪和子长原油进行脱水实验。结果表明，对河庄坪原油，在55 ℃，破乳剂总用量100 mg/L，脱水时间6 h时，TA162824与TEAC以2∶3和3∶2、与DMA以4∶1的比例进行复配，脱水率最高，分别达到99.7%、97.8%；对子长原油，在65 ℃，破乳剂总用量200 mg/L，脱水时间6 h时，TA162824与TEAC以2∶3和1∶4、与DMA以4∶1的比例进行复配，脱水率最高，分别达到97.3%和99.3%。其中TA162824与TEAC以2∶3、与DMA以4∶1的复配物对这两种不同原油的脱水率等性能都好，适应性强。

Abstract: Using organic amine as primer，propylene oxide (PO) and epoxy ethane (EO) as monomer，potassium hydroxide as catalyst，the TA162824 multi-block polyether demulsifier was synthesized and combined with TEAC and DMA at different proportions. Dehydration experiments of the combinational demulsifiers were conducted at 55 ℃ in 6 h at demulsifier concentration of 100 mg/L for Hezhuangping crude oil，and at 65 ℃ in 6 h at demulsifier concentration of 200 mg/L for Zichang crude oil in North Shaanxi oil fields by bottle test. The results showed that for Hezhuangping crude oil at the proportions of TA162824 to TEAC 2∶3 and 3∶2，and that to DMA 4∶1，the highest dehydration rates of combinational demulsifiers were 99.7%，97.8% and 95.8% respectively. For Zichang crude oil，the highest dehydration rates of combinational demulsifiers were 97.3% and 99.3% at the proportions of TA162824 to TEAC 2∶3 and 1∶4，and that to DMA 4∶1. For Hezhuangping and Zichang crude oil at the proportion of TA162824 to TEAC and DMA 2∶3 and 4∶1，the combinational demulsifiers had good dehydration rate and strong applicability.
