Improving Method Research on Producing Condition of Horizontal Well

To relieve the difficult problem that steam huff and puff of super heavy oil vertical well decreases in a high cycle scale,the paper analyzes homogeneity of oil reservoirs,the irregular distribution of remaining oil,and so on.Combined with the application,the cycling preheating can be used to guarantee the horizontal section being warmed by circular steam,double-barreled steaming can be used for infill horizontal well,CO2 profile control,vertical well assisting huff and puff and so on,to improve the use condition of horizontal section effectively and enhance oil recovery.
