Overview

This book presents frontier research in computational mechanics of mine rock mass and tackles the major engineering problems of unconventional oil and gas resources exploitation.  The hydrofracturing, which forms a complex fracture network in deep reservoir rock, is a key technology for oil and gas flow and extraction. The propagation behaviors (such as deflection, penetration, and intersection) and fracture network morphology are crucial to the evaluation and control of oil and gas production. This book mainly introduces from the following three aspects, including deflection of fracturing fracture network disturbed by discontinuity in rock, deflection of fracturing fracture network disturbed by multiple fractures, propagation and deflection of fracturing fracture network in supercritical CO₂ fracturing. The book focuses on the numerical research progresses of deflection of fracturing fracture network disturbed by discontinuity and multiple fractures in rock, which covers the following main contents: (1) dynamic intersection and deflection behaviors of hydraulic fractures meeting granules and natural fractures in tight reservoir rock based on statistical modelling and fractal characterization, (2) deflection behaviors and fractal morphology of hydraulic fractures meeting beddings and granules with variable geometrical configurations and geo-mechanical properties, (3) dynamic propagation of tensile and shear fractures induced by impact load in rock based on dual bilinear cohesive zone model, (4) center- and edge-type intersections of hydraulic fracture network under varying crossed natural fractures and fluid injection rate, (5) wells connection and long hydraulic fracture induced by multi-well hydrofracturing utilizing crossed perforation clusters, (6) deflection of fracture networks and gas production in multi-well hydrofracturing utilizing parallel and crossed perforation clusters, (7) supercritical CO₂-driven intersections of multi-well fracturing fracture network and induced micro-seismic events in naturally fractured reservoir. Given its scope, the book offers a valuable reference guide for researchers, postgraduates and undergraduates majoring in engineering mechanics, mining engineering, petroleum engineering, geotechnical engineering, and geological engineering.
