| Abstract: |
| By using the real triaxial stress frame, the initial pressure changing laws were tested through exerting triaxial stress on the cement samples under different perforation parameters including perforation depth，perforation diameter and the angle of a between the hole axis and the maximum horizontal in-situ stress. The results show that the initial pressure decreases with the perforation depth and diameter increasing, while increases with the angle of a increasing. The conclusions can provide references for the field performance of hydrau-perforating and fracturing. |
