Technical parameters

一、performance

This product has excellent emulsifying ability, which can reduce the interfacial tension between oil and water to 10-3mN/m. By reducing capillary pressure and/or causing capillary end effect, it has good interfacial activity, causing a reversal of rock wettability, reducing capillary resistance and injection pressure, making crude oil easy to peel off and be displaced by displacement fluids, thereby improving oil and gas recovery rate.
