报告摘要：

A newly developed hydraulic fracturing modeling and simulation and its implementation for commercial application will be introduced and compared with existing developments. Various fundamental issues of modeling and simulating hydraulic fracturing will be addressed, including solid deformation and fracture, fluid flow and loss, heat transfer, proppant transport and settlement, temperature-, time-, and proppant-dependent fluid rheology, wellbore fluid mechanics, and perforation erosion. The focus will be on developing rigorous mechanics-based computational models that can be used to simulate multiple fractures on multiple stages along multiple wells in heterogeneous, multiple-layered formation. Various test results will show that the developed simulator is versatile, user-friendly, robust, and efficient, and can be used by fracture engineers to aid in the optimal design of hydraulic fracturing treatments. The current industrial benefits and challenges for effectively utilizing sophisticated fracturing simulators will be discussed.
