预测水平井产能与出砂量的一种新方法

A New Method of Predicting Produtivity and Sand Production of Horizontal Wells

本文用数值法求解描述水平井流动状态的偏微分方程。获得储油层中各节点的压力分布和三个方向上的速度分布，从而计算水平井的理想产能。并建立了储层中砂浓度的场模型，由此预测出砂井的出砂量。

This paper presents a numerical method of solving the partial differential equation that describes flowing law of horizontal wells,by which the idealized productivity of a horizental well can be computed after the pressure profile and three dimentional velocity have been acquired at each node. In addition, a sand concentration profile model in flowing liquid has been established,which can predict sand production of a well that might produce sand.
