摘 要：The M block in Liaohe Oilfield uses steam huff and puff coupled with water flooding, and it has entered the middle-later period of oilfield development To keep stable yield, the development mode should be changed. Based on the geological characteristics in the M block, this paper puts forward two different ways： Horizontal well injects steam to steam drive; Horizontal well as product well when vertical well injects steam. Combined with practical data and using numerical simulation to analysis, the results show that： Horizontal Well injects steam to steam driving is the best way; the recovery percent is as high as 22.72%. This development mode will work no matter in the short run or getting the economic limit rate.
