摘要：As an important index in oilfield development, flood-response time can be used to describe the effect of water flooding in porous media. The responding time in low permeability reservoir is usually calculated by the method of stable state successive substitution neglecting the effect of medium deformation. Numerous studies show that the media deformation has an important impact on the development for low permeability reservoirs and can not be neglected. On the base of streamline tube model, we developed a method to interpret responding time with medium deformation factor. The results show that: the media deformation factor, threshold pressure gradient and well spacing have a significant effect on the flood response time. With the greater the media deformation factor, threshold pressure gradient or well spacing, the flooding response time becomes slower. As the angle with the main streamline increases, the water flooding response time delays as a "parabola" shape.
