TL;DR: In this paper, the authors proposed a method for predicting the crude oil production ratio of a water-drive oil reservoir, which comprises the following steps that the oil field production history is divided into a plurality of development stages according to the data point form of the actual oil field cumulative water output and cumulative oil output which are distributed according to an A type water drive characteristic curve; relations, of the water cut and the recovery degree, containing production parameters in the corresponding development stages are separately established.
