Abstract: One of the best way for well site wastewater reclamation is fracturing fluid preparation. The influence of different inorganic salts type and content on the characteristics of fracturing fluid is studied by simulating the well site wastewater. Research shows that the performance of fracturing fluid is dropped significantly when the inorganic salts content in well site wastewater is more than 1%. High valent cationic such as calcium, magnesium etc. and carbonate root ion affect the performance of fracturing fluid greatly, which shall be removed during the wastewater treatment process.
