对实验室新近研制的硫酸盐型Gemini表面活性剂进行了性能评价，结果表明：该产品具有高的表面活性（最低表面张力26.3 mN·m-1）、低的油水界面张力（最低降到2.71 × 10-3 mN·m-1）和吸附损失、增黏作用、缓蚀防腐作用、乳化降黏等特点。因此，其在油气开采方面具有广阔的应用前景，并且在经济上是可接受的。

The performance of new sulphate Gemini surfactant is evaluated in laboratory. The result indicates that the new surfactant has
a perfect surface activity (minimum surface tension is 26.3 mN/m),low oil/water interfacial tension(minimum interfacial tension is
2.71×10-3 mN/m), adsorption loss, thickening function, corrosion control effect，emulsion visbreaking function, etc. For all these
performances, this surfactant in oil and gas production has a very good foreground in application and it is acceptable in economy.
