Multistage hydraulic fracturing is one of the most prevalent approaches for shale reservoir development. Due to complexity constructing environments experiments, numerical simulation a vital method study flow behavior under conditions. In this paper, we propose model that considers multistage fractured horizontal well with hilly-terrain trajectory in presence natural fractures. The was construc...

Daqing Oilfield is rich in low permeability reservoirs. In order to fully understand the development dynamics of ultra-low reservoirs, this paper takes as an example and studies productivity fractured horizontal Wells by numerical simulation method. The results show that decreases exponentially with decrease formation permeability. well increases fracture length spacing. With increase coefficie...
