Abstract: Water flooding characteristic curve method is an important one to predict water flooding deliverability and recoverable reserve.At the present,the researchers both home and abroad have studied and established tens of expressions for water flooding characteristic curve.All the curves are hard to be used for quantitatively describing the whole process of oilfield development due to the complexibility of the development,they are only suitable for a certain period.Based on several existing new types of water flooding characteristic curves,the new types of water flooding characteristic curves are presented in this paper by combining the second kind of water flooding curve with the tenth kind of water flooding curve and the C kind of water flooding curve with the tenth kind of water flooding curve,the shape and feature of the characteristic curves are studied.The established curves are better matched with practical data,results are more reliable.
