报告内容In this talk we first introduce a kinematical proppant transport model for spherical suspensions in hydraulic fractures developed by Dontsov and Peirce (J. Fluid Mech., vol. 760, 2014, pp. 567-590.). Next, a pseudo-3D hydraulic fracture simulator for multilayered rocks, to capture proppant transport mechanism, is developed. For pressure-driven proppant transport, the bridges made of compact proppant particles can lead to both proppant distribution discontinuity, and higher treating pressure. The model is applied to growth of a fracture from a vertical well, which covers many thin-bedded intervals and more than one opened hydraulic fractured interval. The numerical examples demonstrate that a loss of vertical connectivity can occur among multiple fracture sections, and proppant particles are transported along the more compliant layers, leaving the layers targeted to be untapped. This talk intends to illustrate hydraulic fracturing treatments with proppant transport being affected by and interacting with reservoir lithological complexities.
