以多种端烯丙基聚氧烯醚、 低含氢硅油为原料,氯铂酸为催化剂制得复合型聚醚改性硅油.以复合聚醚硅油为主体,通过添加增效剂、 分散剂制得消泡剂.同目前在用的消泡剂进行对比评价,该消泡剂具有更高效的消泡性能,同时能提高油田在用破乳剂的脱水能力,具有较高的应用推广价值.%The composite polyether modified silicone oil was prepared with a variety of end allyl polyethy-lene oxide ether, low hydrogen silicone oil as the raw materials, chloroplatinic acid as catalyst by grafting modification. The defoaming agent was prepared with the composite polyether silicon oil as the main materials, adding a synergistic agent and disperse agent. Compared with the anti-foam agents used in oilfield in Bohai, the anti-foam agent has more efficient performance, and can improve the dehydration ability of the oil field, with good application.
