摘　　要：以树脂为起始剂、环氧乙烷和环氧丙烷为单体、KOH为催化剂,在环氧丙烷开环聚合温度为(130±5)℃、环氧乙烷开环聚合温度为(120±5)℃、压强低于0.5MPa的条件下,合成嵌段聚醚型破乳剂单剂AR81610,并与助剂TEAC、DMA用不同比例复配,对陕北油田有代表性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100mg.L-1、脱水时间6h条件下,AR81610与TEAC、DMA复配比例为2∶3时,脱水速率快,脱水率最高,分别达到99.7%、93.8%;对子长原油,在65℃、破乳剂总用量200mg.L-1、脱水时间6h条件下,AR81610与TEAC复配效果最好,当复配配比为3∶2时,脱水速率快,脱水率最高,达到99.3%;且复配物脱出的水清不含油,无悬浮物,油水界面整齐。Using resin as primer, propylene oxide （PO） and epoxy ethane （EO） as monomer, potassium hy- droxide as catalyst, the ARS1610 multi-block polyether demulsifier was synthesized at less than 0.SMPa and at （130＋5）℃ for PO and at （120＋5）℃ for EO, to combine with TEAC,and DMA with different proportion. Dehydra- tion experiments of the combinational demulsifiers have done at 55℃ in 6h and with demulsifier concentration of 100mg .L-1for Hezhuangping crude oil and at 65℃ in 6h and with demulsifier concentration of 200mg ·L-1 for ZiChang crude oil in North Shanxi oil fields. The results showed that for Hezhuangping crude oil, the dehydration rate of combinational demulsifiers was highest to 99.7% and 93.8%, and dehydration speed was rapid when the proportion of AR81610 to TEAC and DMA was 2：3. For Zichang crude oil, the combinational demulsifiers of ARS1610 and TEAC have the best dehydration effects, and when the proportion of ARS1610 to TEAC was 3：2, the dehydration rate was highest to 99.3%, and dehydration speed was rapid. There was no suspended matter in the separated water, separated water was clear, interface between oil and the water was homogeneous by using combi- national demulsifiers.
