Nine kinds of heavy oil thermal recovery models are summarized,including non-Newtonian power-law fiuids model,two-region composite reservoir model,three-region composite reservoir model,multi-region composite reservoir model,model with consideration of gravity override and interference testing well model,etc.Pressures and pressure derivatives are briefly analyzed.Advantages and disadvantages of models are compared.Problems in current models and trends in research of heavy oil well test are pointed out.
