摘      要：A systematic model development for oil flow in quasi-3D(1Dþ2D)is *** approach provides a unified modeling ***,additional terms are obtained,which allows for tubing area variation along the flow *** area variation can be modeled as analytic function or random fluctuation,as it could be the result of deposits or tubing internal surface *** proposed approach can be used to obtain analytic solutions which provide physical insight into the phenomena under scrutiny,including the validation of software tools,sensor development and sensor *** starts from conservation laws as given by kinetic theory and applies the transverse averaging technique(TAT)to extract the one-dimensional approximation in formal *** demonstrate its application,the steady-state Ramey’s model,the Hasan’s transient model and a simple two-phase model are generated from the obtained equations.
