Summary:
Sanding is one of problems which prevent efficient producing in oil fields. When we produce fluid resource, small sand particles are generated by breaking of reservoir rocks. These particles flow with fluid resources and prevent its ample liquidity. This results in the reduction of production. Since the sanding results in the reduction of production, it is important to understand the mechanism of the sanding in order to formulate and effective policy. For the fundamental study to know the mechanism, we researched about how each fluid parameter work to that phenomenon by numerical simulation. From the result, when viscosity of fluid is higher, the effect of flowing particles becomes lower. And closing of pore gives effect to producing effeicency until it breaks.
