Optimization of Development Mode during the Later Steam Huff and Puff in Heavy Oilfield

Abstract:

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.
