Product Description
During the fracturing and acidifying operation of oilfield, the working fluid should be discharged out of the ground rapidly and completely after operation to avoid secondary pollution to the formation and increase output and injection. However, the residue liquid cannot be discharged completely as the surface tension is usually too high; when cleanup additive is added, the surface tension can be lowered efficiently, the interfacial activity can be improved, and this is favorable to rapid and complete flowback of working fluid. In addition, when cleanup additive is added into the working fluid, the interfacial tension can be effectively lowered to facilitate the injection of working fluid. Cleanup additive is a product developed for acidifying and fracturing operation of oilfields, high-efficient full-fluorine surfactant is added, it has stronger capacity in lowering the surface (interfacial) tension, and acid/salt resistance. Even under the condition of concentrated acid and high salt, the cleanup additive can still reduce the surface (interfacial) tension, alleviate Jamin effect, ensure easy discharge of residual liquid from formation; besides, it also has the advantages of less dosage, high performance/price ratio, excellent compatibility, easy operation, high temperature-resistance, etc.
