摘　　要：气田开采过程中因使用大量泡排剂造成含醇污水起泡现象严重,这对精馏塔的稳定运行产生了不利影响。以起泡高度为评价指标,研究了甲醇含量、凝析油含量、温度和压力对泡排剂发泡性能的影响,并以甲醇浓度、凝析油含量和压力、温度为因素进行正交设计试验。试验结果表明:当甲醇含量超过40%时,基本不起泡,凝析油和压力对泡排剂UT-6的起泡能力有一定的抑制作用,温度对泡排剂UT-6发泡性能有促进作用。正交试验表明,各因素对泡排剂发泡性能影响顺序是:甲醇浓度>温度>凝析油含量>压力。The use of a lot of roam drainage agent makes alcohol containing wastewater bubble in severe cases in the process of gas field exploitation, and that offect the stable operation of the rectifying column. Using foamine height as evaluation indexes, the effect of methanol concentration, condensate oil content, temperature and pressure on the properties of-foam drainage agent is studied. Serving as influential factors, they were studied by orthogonal design test. The experimental results suggest： when the content of-methanol is more than 40%, the sewage basically has no bubbles, condensate oil and pressure have certain inhibitory effect on foaming performance of-toam drainage agent UT-6, temperature promotes foaming of roam drainage agent. By orthogonal test, the order of affecting factors is determined. They are methanol concentration, temperature, condensate oil content and pressure.
