Investigation on nonlinear multi-scale effects of unsteady flow in hydraulic fractured horizontal shale gas wells被引量:2
《Applied Mathematics and Mechanics(English Edition)》2018年第2期181-192,共12页Jiaxuan LIU Xinchun SHANG Weiyao ZHU 
supported by the National Basic Research Program of China(973 Program)(No.2013CB228002)
A unified mathematical model is established to simulate the nonlinear unsteady percolation of shale gas with the consideration of the nonlinear multi-scale effects such as slippage, diffusion, and desorption. The cont...
