本文根据断裂力学理论,全面考虑了压裂中各施工参数和地层参数对垂直裂缝延伸形状的关系,建立了较文献[1]更接近实际的理论,编制了适合现场应用的计算机程序框图。其计算结果与实践很吻合。用文中提出的计算程序可以方便地预测垂直裂缝的高度及遮挡层能否压开等问题。 According to the theory of fracture mechanics, the relationship between the construction parameters and the formation parameters of vertical fractures in fracturing is fully considered. A more realistic theory than literature [1] is established and a computer program block diagram suitable for field application is compiled. The calculation results are in good agreement with the practice. The calculation program proposed in this paper can be used to predict the vertical crack height and whether the obstruction can be opened or not.
