【 摘 要 】

BCG-CO2 fracturing fluid system is especially suitable for shale gas stimulation with advantage of minimizing the actual water consumption, reducing the damage to formation, recovering more rapidly and efficiently, etc. A major objective of this article is to ascertain the friction performance of BCG-CO2 fracturing fluid in a wide range of experimental conditions for guiding the selection of fracturing parameters. The experimental results showed that the frictional resistance coefficient levels off under the flow velocity greater than 1 m/s. For the impact of the foam quality on the friction resistance coefficient, the completely opposite change rule is showed under foamed and unfoamed conditions.
