Abstract

For heavy reservoirs with different rheological fluid, the diverse phenomena may appear in the fluid flow. Based on the rheology experiment, the actual rheological equations are figured out in district A. With the detailed type of fluid, the fundamental formulas about pressure loss and temperature are reasonably selected, by which, the model for production prediction are defined as the basis for the calculation of pressure distribution along the pipe. As Beggs-Brill method has just made a prominent contribution to the slippage area, the wellbore pressure distribution is obtained through basic momentum equations, in which the pressure drop is calculated only based on the average parameters, such as density, viscosity. The impact caused by slippage between steam-liquid phases has yet been neglected. Particularly, when the steam dryness is relatively low, and the slippage does exist, the result is obviously not scientific. Therefore, with some modified parameters, this paper proposes a new process by the involvement of Beggs-Brill method, and describes the process in detail with on-site data to test and verify the feasibility. It turns out that BeggsBrill method is suitable to calculate pressure distribution, where the process and the model for production prediction are also applicable in this district.
