摘　　要：根据水平管中单相液流的压降计算公式和多相流体力学的能量守恒原理，导出了流体进入水平井段五种情况下的沿程压降计算公式和水平井井筒压力分布预测模型。试算表明，该模型满足工程要求，对油田生产有参考价值。On the basis of pressure drop calculation for liquid flow in the horizontal tube and the energy conservation of multiphase fluid mechanics. the pressure drop calcu lation-formula that fluid flow into horizontal section for five kinds of conditions and the method for prcdicting the presure distribtl tion in the wellbore of horizontal well were derived. The calculated example shows that the precision is satisfied for petroleum engineering and there is an important reference for oilfield production.
