摘　　要：主要提出了无限导流和恒定井筒压力的假设条件对于水平井来说是毫无价值的,并且将井筒水力学的影响考虑到了水平井产量的评估中。其中井筒水力学包括摩擦力、加速度、重力和流体流量。井筒水力学模型不要求使用油藏模拟,使用更方便,并且可以用来确定水平段的最佳长度,从而最大限度地提高井的产量。The paper puts forward that the assumption of infinite conductivity and constant wellbore pressure for a horizontal well is invalid and considers the effect of weUbore hydraulics into the evaluation of the productivity of a horizontal well.Wellbore hydraulics includes the effects of friction, acceleration, gravity, and fluid inlux.The weUbore hydraulics model does not need the use of a reservoir simulation which is more easily.And it can be used to determine the optimum length of the horizontal section in order to maximize productivity of the well.
