本文详细介绍了一种新的非离子型油包水型乳化泥浆乳化剂的室内研制和油田应用情况,该乳化剂是以炼厂副产品环烷酸和二乙醇胺为原料采用最佳合成工艺路线和简单的流程,在一定温度等条件下使酸与二乙醇胺成盐,然后脱水形成酰胺产品。该产品与其他乳化剂复配所制成的油包水乳化泥浆能抗150℃以上高温,悬浮稳定性好。经中原油田三口井上使用效果良好。
In this paper, a new non-ionic water-in-oil emulsified emulsion emulsifier indoor development and field applications, the emulsifier is based on the refinery naphthenic acid and diethanolamine by-product of the best synthetic route and A simple process, salt and diethanolamine salt at a certain temperature and other conditions, and then dehydrated to form amide products. The product and other emulsifiers made of water-in-oil emulsified slurry can resist high temperatures above 150 ℃, good suspension stability. The three wells in Zhongyuan Oilfield use well.
