| Abstract: | The forming and characteristics of visco - elastic surfactant （VES） system were introduced. The visco -elastic surfactant comprising cationic quaternary ammonium salt and betaine as primary components and sodium orthohydroxyl benzoate as accelerant in clean fracturing fluid was prepared. The system could be used at higher oil reservoir temperature of 70 - 100 ℃ compared with that at 60 ℃ showing the heat - resistance of clean fracturing fluid was obviously improved. The effects of water soluble fiber on the settlement rate of fracturing sand supporting agent in the fracturing fluid were examined. The result showed that the sand - carrying capacity could meet the requirements after adding 1% water - soluble fiber into clean fracturing fluid. |
