在大量实验基础上,提出以凝析油为主体溶剂,添加30%～50%经处理的焦煤油,再加0.1%～0.5%的表面活性剂,通过乳化、增溶作用成为一种新型复合溶剂体系。此溶剂对沥青、石蜡及胶质具有很好的溶解能力和解堵效果,且溶剂原料易得、价格低廉、无毒,便于油田使用。 Based on a large number of experiments, it is proposed to use condensate oil as the main solvent, add 30% ~ 50% treated coker kerosene, and add 0.1% ~ 0.5% surfactants to form a new type of composite through emulsification and solubilization Solvent system. The solvent on asphalt, paraffin and gum has a good ability to dissolve and plugging effect, and solvent raw materials available, low cost, non-toxic, easy to use oil fields.
