摘    要:设计并建立了水平井筒变质量流动模拟实验装置。对具有射孔完井的水平井筒变质量流动进行了实验研究,利用先进的数据采集系统获取了大量的实验数据。对水平井井筒单孔眼段流动阻力损失分析可知,流动阻力由三部分组成:管壁摩擦阻力、加速损失和混合损失。对实验数据进行处理得出了混合损失和主流流速与孔眼流速之间的关系。对于一定的主流流速,混合损失随孔眼流速的增大而增大,同时,对于一定的孔眼流速,混合损失随主流流速的增大而增大,此时孔眼的流入对水平井筒中的流动造成的影响比较显著。孔眼的流入增加了井筒中流动的复杂性。对实验数据进行的回归结果表明,在本实验条件和范围内,主流流速和孔眼流速是造成混合损失的主要因素。

关 键 词:水平井筒  变质量流动  阻力损失  混合损失  孔眼  油藏

Abstract:Experimental simulation system is employed to investigate the variable mass flow in perforation completed horizontal wellbore. Experimental data show that inflow through perforation has a great effect on the flow resistance in the horizontal wellbore. It is found by analysis that the flow resistance in the horizontal wellbore is made of three parts: wall friction loss, acceleration loss and mixture loss, and the mixture loss is mainly influenced by main flow velocity and perforation flow velocity. In fact, for constant main flow velocity,the mixture loss increases with the increasing of perforation flow velocity, and for constant perforation flow velocity, the mixture loss will also increase with the increasing of the main flow velocity.
Keywords:horizontal wellbore  variable mass flow  resistance loss  mixture loss
