Abstract: With the longer duration of fire flooding in Gaosheng oilfield,gas production in oil wells increased,which resulted in problems such as normal mixing light oil could not be done and the efficiency of oil well pump was low.Therefore,corresponding matching research and experiment have been carried out,and then the techniques and methods suitable for gas production management and control of deep heavy oil fire flooding have been provided.The achieved good application results can provide guidance for deep heavy oil fire flooding in the next step.
