Multistage hydraulic ,fracturing, is a key technique for the effective exploitation of tight reservoirs. In the process of multistage hydraulic ,fracturing,, a large amount ,of fracturing fluid, is injected into the formation. However, field data show that the ,flowback, rate of the ,fracturing fluid, after ,fracturing, is generally no higher than 30% [1].
