Based on the value difference between true flow velocities in oil and water 2 phase flow in horizontal wells, a model for interpreting slippage velocity of 2 phase flow is established, and field application is carried out with better result.

• 针对水平井油水两相流动中油水各相真实流动速度之间的差异，建立了油水两相流动滑脱速度解释模型，并在现场进行了试处理，试用效果较好。
