摘　　要：研究了变形双重介质分形油藏渗流问题的压力不稳定响应,考虑了储层的双重介质特征和分形特征以及应力敏感地层中裂缝发生形变的问题,建立了应力敏感地层双重分形介质数学模型,采用数值方法以求解数学模型;此外,还给出了典型的压力曲线图板,并利用这些图版对模型中的有关参数进行了敏感性分析,探讨了分形参数、变形参数、双重介质参数以及井筒储集系数变化时压力的变化规律。This paper studies pressure instability of deformable dual media fractal reservoir seepage in response, analyzed the problems of reservoir dual medium characteristics and fractal characteristics and stress sensitive formation of crack deformation, and set up stress sensitive formation double media fractal mathematical model. Numerical calculation method is adopted to solve the mathematical model. In addit- ion, a typical pressure curve drawing is used in the model parameters in relation to the sensitivity analysis. Finally, the fractal parameter, deformation parameters, dual medium parameters, and wellbore storage coefficient variation with the pressure variation are discussed
