引言稠油生产中，与使用稀释剂有同样效果的另一种方法是使用表面活性剂，以在井筒中形成连续水相的乳状液。它能同疑析的或轻质的碳氢稀释剂降粘一样，用以解决抽油杆下落、泵的砂卡和提高油杆运动速度的问题。图1为原油和在合理温度域内形成的乳状液粘度。当形成的乳状液以水
Introduction Another method of producing heavy oil that has the same effect as using a diluent is the use of a surfactant to form a continuous aqueous emulsion in the wellbore. It can be the same as the thinning or dilute thin hydrocarbon diluent, used to solve the whereabouts of the sucker rod, pump sanding card and improve the rod speed. Figure 1 shows the viscosity of the crude oil and emulsion formed in a reasonable temperature range. When the formed emulsion with water
