摘要
Field practices show the adaptability of the water displacement curve at the ultra-high water-cut stage is poor. The authors first proposed a new water displacement curve, and then put forward a new method to obtain the parameters in the new curve equation. Then a new characterization equation to describe the relationship between water-oil relative permeability ratio and water saturation is proposed, which is the new water displacement curve's theoretical basis. Finally, based on the case study it is proved that the new curve are more accurate in predicting the development performance at the ultra-high water-cut stage.
