【 摘 要 】

Multi-stage fractured horizontal wells play an important role in developing shale gas reservoirs by significantly improving productivity. With the introduction of nonlinear desorption into matrix governing equations, a numerical model is developed to study the production composition of fractured horizontal wells in shale gas reservoirs. The results show that the production composition is majorly influenced by matrix permeability of inner zone, and spacing of secondary fractures.
