原始语种摘要: Abstract(#br)This paper presents the results of a study on pressure buildup analysis of a vertically fractured well with the consideration of stress-sensitive permeability and hysteresis effect in fracture. A new function was established to better characterize the variation of fracture permeability on pore pressure, and a mathematical model was derived for the buildup test of fractured wells with stress-sensitive conductivity. Several simulation cases involve various conductive fractures were run to plot pressure buildup type curves under stress damage condition. The influence of stress effect on buildup behavior and the variation of the fracture conductivity are discussed extensively. Results of this investigation demonstrate that for stress-sensitive conductivity fractured wells, a...
