摘要: 实验研究表明,压力变化范围较大时,渗透率模量呈非线性变化。在研究渗透率模量随压力变化规律的基础上,建立了裂缝渗透率变化模型和变渗透率模量双重孔隙压敏介质油藏压力动态模型,采用全隐式有限差分格式进行差分,迭代求解,并对各个参数的敏感性进行了分析。

Abstract: The experimental study shows that there is a non-linear relationship between permeability modulus and pressure drop in a large range of pressure variation. This paper presents the fractural permeability variation model and the variable permeability modulus pressure behavior model for dual porosity reservoir based on the experimental study results. The implicit finite difference method is used to discretize the formulation and the iterative method is used to resolve the above mentioned nonlinear equations. According to the calculations the sensitivities of each parameter in the model are analyzed.

Key words: permeability module, dual porosity, media, pressure behavior
