原始语种摘要: Abstract(#br)Research investigations on three‐dimensional (3‐D) rectangular hydraulic fracture configurations with varying degrees of fluid lag are reported. This paper demonstrates that a 3‐D fracture model coupled with fluid lag (a small region of reduced pressure) at the fracture tip can predict very large excess pressure measurements for hydraulic fracture processes. Predictions of fracture propagation based on critical stress intensity factors are extremely sensitive to the pressure profile at the tip of a propagating fracture. This strong sensitivity to the pressure profile at the tip of a hydraulic fracture is more strongly pronounced in 3‐D models versus 2‐D models because 3‐D fractures are clamped at the top and bottom, and pressures in the 3‐D fractures that are far removed from...
