摘要
水平井、斜井由于井身倾斜以及井筒周围空间的非对称性使井下流动状态与垂直井极不相同。通过多相流动试验研究,分析了斜井、水平井流型的变化,以及井斜角对速度剖面分布及滑脱速度的影响。得到了不同井斜角情况下速度剖面校正系数、滑脱速度与液流量、持水率的关系图版。
Because of deflection and unsymmetrical space around in horizontal and deviated wells, downhole flow status is much different from vertical wells. The changes of flow patterns in deviated and horizontal wells and the effect of deviation angle on velocity profile distribution and sliding velocity are analyzed, chartboards of the relations between velocity correction of coefficient, sliding velocity and fluid flow rate and water holdup are established.
