摘　　要：提供了一种计算斜井流压和井筒中压力分布的方法，该方法首先把斜井修正成直井，然后应用三段法，依据环空及井筒的流体特性多数和井柱及地层参数计算出井筒压力分布和流压，模型求解采用迭代法。通过11口井的实际应用，所得结果合理可靠，可以用来指导动态分析和共合理工作制度的选取。Provided a method for calculating the flowing pressure in inclined well andthe pressure distribution in well bore. The method firstly modified inclined well into verticalwell, then, by the appl1catlon of the 3-member method, calculated the pressure distributionand flowing pressure in well bore based on the fluid characteristics parameters in annular andwell bore as well as the parameters in formation- lteration was applied in the solution of themodel. The method had been used in 11 wells, the calculated values were reasonable and re-liable, and could be used to direct the performance analysis and the reasonable work1ng sys-tem option of well.
