| 摘 要： | 以多种阴离子、非离子表面活性剂和助剂为原料，通过复配和筛选，制得阴离子／非离子表面活性剂复配体系。考察了原油含水量、复配体系加量和温度对其降粘效果的影响，确定了最佳条件：原油含水量25％，阴离子／非离子表面活性剂复配体系加量0．3％。在此条件下，对东辛油田不同区块稠油的降粘率达95％以上，沉降脱水率达90％以上。

| Abstract: | A anion/nonion surfactant compounded system was prepared with several kinds of anion surfactants,non- ion surfactants,and assistants as raw materials by compounding and screening.The effects of water content of crude oil,the amount of compounded system,and temperature on the viscosity-reducing efficiency were investigated.The optimum conditions were determined as follow:water content of crude oil 25%,the amount of anion/nonion surfac- tant compounded system 0.3%.The viscosity-reducing rate and dehydration rate on viscous crude oil from different region in Dongxin Oilfield were up to 95% and 90% respectively. |
