Abstract

A physical model based on flow rate testing instrument used flow-concentrating horizontal wells is established. According to the continuity equation and momentum conservation equations, a mathematical model of oil-water two-phase flow is derived. The model is discretized and solved by the FEM method and GMRES method. In the case of low flow rate, the flow pattern and the speed field through flow-concentrating pipe is simulated. The simulation results show that the time to reach a stable flow pattern is closely related to the inlet velocity when the horizontal pipe diameter is 34mm, and the velocity field is not the same at different heights of the pipeline and has relatively large changes.
