主 题：Water flooding characteristic curve high water cut period production dynamic prediction recoverable reserves water flooding
摘 要：The oil production predicted by means of the conventional water-drive characteristic curve is typically affected by large deviations with respect to the actual value when the so-called high water-cut stage is *** order to solve this problem,a new characteristic relationship between the relative permeability ratio and the average water saturation is *** comparing the outcomes of different matching methods,it is verified that it can well reflect the variation characteristics of the relative permeability ratio *** the new formula with a reservoir engineering method,two new formulas are derived for the water flooding characteristic curve in the high water-cut *** practicability is verified by using the production data of Mawangmiao and Xijiakou *** results show that the error between the predicted cumulative oil production and production data of the two new water drive characteristic curves is less than the error between the B-type water drive characteristic curve and the other two water drive characteristic *** is concluded that the two new characteristic curves can be used to estimate more accurately the recoverable reserves,the final recovery and to estimate the effects of water flooding.
