Based on the principle of isotope tracer in single well, and combing with well-theory of seepage flow, a mathematic model of two-dimension fissure network is proposed in the paper.
在应用单孔同位素示踪原理的基础上，结合地下水渗流井流理论，建立了二维裂隙网络的渗流计算模型。

According to seepage characters and fissure distribution in fractured low permeability oil reservoir, equivalent model to simulate the fluid flow in fractured reservoir was set up.
The mechanics apperances and effects of the interaction on the flow in the soil fissure are discussed. The internal relationships in coupling effect and control between them are studied.
