大量实验和现场数据表明,低渗透油藏中普遍存在启动压力梯度,并且裂缝对应力的敏感比基质更强,文中在双孔、双渗达西渗流的数学模型基础上引入启动压力梯度和应力敏感,建立了裂缝性低渗透油藏双孔、双渗渗流模型,并对其进行了全隐式联立求解以及实例计算。
关键词: “ 连续型” 油气藏;“ 连续型” 油气藏评价;FORSPAN 模型

Alarge number of experimental and field data showthat starting pressure gradient exists in low permeability reservoirs and fracture is more sensitive than the matrix for stress. Based on dual porosity/dual permeability Darcy seepage flow mathematical model, pressure gradient and stress sensitivity are introduced. A seepage flow model in fractured low permeability reservoir is established, and a full-implicit simultaneous solving and examples calculation are carried out.
