Abstract: This paper describes a three-dimentional,three-phase,multi-component thermal and chemical simulator,which can be used to simulate the steam injection process in a horizontal well.The model dynamically incorporates wellbore hydraulics by taking into account two types of flow,that is,laminar and turbulent flows. The fully implicit wellbore equations and reservoir equations are solved with adaptive implicit formulation and an advanced numerical solution method.The grid system is very flexible,it may be cartesian,cylindrical,local grid refinement as well as bybrid grid.Using this model,a simulation study on thermal recovery of an extra-heavy oil reservoir in Liaohe oilfield with horizontal well is conducted.
