摘要: 对油藏中一个水平井井筒内单相及两相流动特性进行了数值计算研究。由于所用油藏模型压力分布比较复杂,使得水平井的流动计算变得相当复杂,应用表征流动特性的非线性方程对空间进行迭代计算,再向时间推进。计算结果表明,水平井渗流量表现为两端高、中间低的特征,水平井内压力分布趋于下降的特征。所开发的计算程序具有实用性,可为水平井的设计开采提供一定的参考。

Abstract: The single-phase and two-phase flow behaviors of the horizontal well in the oil reservoir are investigated numerically.Due to the complexity of pressure distribution of the reservoir model,it has difficulty in calculation of flow behavior in the horizontal well.The control equation of the flow is resolved numerically.The calculation results show that the influxes are in the shape of U,and the pressure is lowered gradually.The calculation program developed in this paper can be directly applied to the engineering design of horizontal well production.

Key words: horizontal well, pressure distribution wellbore pressure drop, influx, theoretical calculation
