This paper discusses approaches to calculating the productivity of oil wells. Existing solutions do not allow taking into account many important factors, such as, for example, hydraulic resistance in the wellbore, wellbore trajectory, etc. The article presents a developed numerical method for modeling oil flow to an oil well with a complex wellbore trajectory along the productive formation. Based on the function for the point flow potential and the method of hydraulic calculations, an original solution was obtained, which takes into account not only the change in pressure and flow rates for individual sections of the well, but also the hydrodynamic imperfection of the well.
