油气开采用新型硫酸盐型Gemini表面活性剂

A new sulphate Gemini surfactant for oil and gas recovery

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 interracial tension （minimum interracial 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.
