摘要:

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。

Abstract:

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 horizontal well can be computed after the pressure profile and three dimensional 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.

Key words: horizontal well, well sand production, well production rate, well performance, mathematical model
