Time variability of reservoir parameters in water flooding has an effect on oilfield development rules. Meanwhile, time variability of different reservoir macro-parameters has certain synergetic relationship with each other. Based on microscopic network simulation and reservoir numerical simulation, a new simulation method is presented, which can describe the influence of reservoir parameters’ synergetic time-variability on oilfield development rules both in macroscopic and microscopic scales. Microscopic network simulation can effectively simulate the impact of micro-parameters’ variation on macro-parameters, thus a comprehensive model is built to reflect the variability of reservoir parameters. On the basis of considering time variability of porosity, permeability, and relative permeability in water flooding, an improved reservoir numerical simulator is established, which can effectively simulate the effect of reservoir parameters’ synergetic variation on oilfield development rules.

开发规则对储层参数协同时变的数值模拟。

注水过程中储层参数的时变性对油田开发规律有影响。同时，不同储层宏观参数的时变性具有一定的协同关系。在微观网络模拟​​和油藏数值模拟的基础上，提出了一种新的模拟方法，可以从宏观和微观两个角度描述油藏参数协同时变对油田开发规律的影响。微观网络仿真可以有效地模拟微观参数变化对宏观参数的影响，因此建立了反映油藏参数变化性的综合模型。在考虑注水时孔隙度，渗透率和相对渗透率的时间变化性的基础上，
