摘要(Abstract)：

风城油田采用双水平井SAGD技术开发超稠油取得成功,但是SAGD采出液温度高,乳化程度高且复杂,油水分离困难.通过基本物性分析、显微照相和Zeta电位测定,分析SAGD采出液稳定机理,研究预脱水和热化学脱水、掺柴油降黏辅助脱水技术,研制耐温预脱水剂SB-1和正相破乳剂KL-1,形成SAGD采出液高温密闭脱水工艺.结果表明,SAGD采出液掺入质量分数为10%的柴油,在140℃温度条件下进行预脱水和热化学脱水,净化油含水率小于2%,脱出污水含油质量浓度小于8.0g·L-1,投产年处理量为30×104 t原油的高温密闭脱水试验站,实现风城油田当前SAGD采出液的全部处理.
