水力压裂裂缝高度的控制技术及其成功应用

Tech of Controlling Crack Height by Hydraulic Fracture and Its Application.

以压裂中可能形成垂直裂缝的井层为对象,从理论出发阐述了影响水力压裂裂缝高度的因素,指出了压裂施工中影响裂缝高度延伸的可控因素和非可控因素,并据此原理在现场进行了裂缝高度的控制探索,取得了成功。

Taking object of well may be forming vertical crack in fracture,factors of influencing crack height by hydraulic fracture are illustrated theoretically and controlled factors of affecting prolong of crack height are indicated.According to this theory,a success has been gained for exploration being conducted of controlling crack height.
