The water drive curve is an important dynamic evaluation method for long-developed waterflood oil fields in listed reserves evaluation.In order to accurately and quickly obtain the annual oil production by water drive curve method in listed reserves evaluation, and avoid iterative calculation to solve the annual oil production by the curve intersection method, the linear relationship between WOR and cumulative water production is studied and proved.A recursion formula of WOR for calculating the annual oil production is proposed.The calculation results show that this method can take into account the variation of the number of wells to be opened in the future, i.e., the future total production variation,and the cumulative error of the calculated results is within 0.6% compared with the iterative calculation by the curve intersection method.It can meet the precision requirement of the water drive curve method in listed reserves evaluation, and improves the efficiency of obtaining the annual oil production by the water drive curve method in listed reserves evaluation.
