摘要
为了研究固相颗粒在裂缝性储层中的暂堵规律,利用表面生成和合成原理建立了裂缝宽度的数学模型,依据固相粒子在裂缝中的堵塞机理对粒子在裂缝中的架桥规律做了模拟试验,并用函数逼近和数据拟合的方法对试验结果进行了处理。基于模拟试验得到的架桥规律,可以在已知裂缝参数的情况下根据架桥距离选择粒子尺寸,从而为通过中性粒子实现裂缝性储层的暂堵提供定量依据。
In order to investigate the temporary plugging behaviors of solid particles in fractured reservoir, a mathematical model of fracture width has been built by using the principles of surface generation & synthesis, and the plugging behaviors of solid particles in fractures have been simulated according to the plugging mechanism of solid particle. Finally, the simulation results are processed by function approximation and data fit. Based on plugging behaviors from the simulation, it is likely to select particle size from plugging distance when the fracture parameters are known, thus providing a quantitative base for the temporary plugging of neutral particles in fractured reservoir.
