耐温耐盐起泡剂的制备及性能
Preparation and performance of temperature and salt resistant foaming agents
摘要
Abstract
For high-temperature and high-salinity oil reservoirs,the foaming agent CDSD-E was prepared using cyclodextrin(CD),sodium dodecylbenzene sulfonate(SDBS),and ethylene glycol(EG)as raw materials.The foaming and foam-stabilizing abilities,temperature resistance,salt resistance,and oil resistance of CDSD-E were investigated.The experimental results show that the optimal ratio of CD,SDBS,and EG is determined as m(CD)∶m(SDBS)∶m(EG)=1∶0.8∶0.3,and the optimal content of CDSD-E is set at 0.4%(w).Under the conditions of 180℃,the mineralization degree of 260 g/L,and the kerosene content of 50%(w),0.4%(w)CDSD-E solution shows foaming volume of 474 mL and foam half-life of 1 135 s.These results indicate that CDSD-E has excellent foaming and foam-stabilizing abilities in high-temperature,high-salinity,and high-oil environments.关键词
