新型磺酸基Gemini表面活性剂的合成及其在油气井中的应用性能
Synthesis of a novel sulfate Gemini surfactant and its application in oilfield
摘要
Abstract
A type of betaine Gemini surfactant(B18-4-18)was synthesized by two-step reaction with N-(3-dimethylaminopropyl)oleoylamide,3-chloro-2-hydroxypropanesulfonate,and 1,4-dibromobutane as main raw materials. The structure of the product was characterized by Fourier transform infrared spectroscopy and 1H nuclear magnetic resonance spectrum. The surface tension curve and related parameters were acquired by surface tension measurements. Liquid carrying rates of B18-4-18 were measured by carrying capacity ratio measurement device in water,mineralized water,methanol solution,and condensate solution,respectively. The foam heights with different types of surfactants were determined by a Roche bubble instrument. The experimental results showed that the structure of the synthesized compounds was in conformity with the expected structure of surfactant. The critical micelle concentration of B18-4-18 was 5.0×10–6mol/L;the corresponding surface tension was 31.67mN/m at 25℃. The highest carrying capacities of the B18-4-18 with the mass fraction of 0.5% were 90%,87%,78% and 87% in water,in mineral water,in methanol solution and in condensate solution,respectively. In contrast to the foaming properties of other surfactants,for the foam acid, the best foaming agent is the B18-4-18.关键词
