| 英文摘要 | Understanding of the fracture network propagation behavior is necessary for improvement of hydraulic fracture operation in shale gas reservoirs, in particular under the influences of geological and field operation parameters. In this paper, a three-dimansional numerical model was used to simulate the propagation of the hydraulic fracture network in field scale, considering a wellbore-fracture-pore triple flow system under the full hydromechanical coupling. The numerical model was verified by simulating the propagation and interaction between natural and hydraulic discontinuities. Finally, the numerical model was applied to evaluate the behavior of complex fracture propagation in hydraulic fracturing operation in a shale gas reservoir based on field operation parameters. Some conclusions can be drawn: (i) both tensile and shear cracking can occur during the hydraulic fracture network propagation, depending on the stress anisotropy and deviation of natural discontinuities; (ii) a certain deviation of natural and layered discontinuities from principal stress directions is one of the main preconditions for forming a complex fracture network under high-stress anisotropy; (iii) a relatively larger control volume can be obtained when the natural fractures are orthogonally crossed and the complexity factor of the fracture network is higher when the cross type is X; and (iv) adequate fluid viscosity should be applied to control the fluid leak-off, thus increasing the complexity and extent of the stimulated reservoir volume. These results can provide a theoretical basis for the optimization of the hydraulic fracturing in shale gas reservoirs. |
