Abstract: 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.
