In the process of hydraulic ,fracturing,, a great amount of ,fracturing, fluids retain in the reservoirs, which are difficult to ,flowback,, forming water phase trap damage and hindering gas production. In addition, large-scale complex fracture networks formed by hydraulic ,fracturing, can communicate micron-scale cracks, but it is still difficult for gas in the nano-scale pores of the matrix to enter the crack.

Fracturing-,fluid flowback, is simulated with the use of a developed simulator. A hydraulically fractured horizontal well with a 1200 m horizontal wellbore and 15 fracturing stages situated in the center of a shale reservoir (1500 m × 560 m × 40 m) is considered. The initial reservoir pressure is 25 MPa.
