Estimation of fracturing scale.
| | Layer | Fracturing fluid utilization(%) | Fracturing fluid injection volume (m3) | Volume of fracturing fluid flowback (m3) | Coefficient in Equation (1) | Coefficient in Equation (1) | Time of fracturing fluid entry into the reservoir (h) | Fracturing cracks area (m3) |
| | The lower layer | 0.98 | 45000 | 2250 | 0.152 | 0.69 | 114 | 474957 | | The upper layer | 0.98 | 45000 | 2250 | 0.19 | 0.72 | 114 | 374189 |
