Injection production ratio is an important basis which is used for studying injection production balance condition and adjusting correlation between injection and production.It also is an index which serves as weighing the degree of artificial supplementary energy and underground deficit during some period. An injection production ratio predication model is constructed basing on the theory of water flooding and the principle of injection production balance. According to the veryfying results of reservoir numerical simulation, tiis mathematical model has a high precision; the pilot prediction results indicate that it can be used for predicting injection production ratio in all kinds of water cut period over every fracture degree oil field. A good injection production project need to be stipulated for so that the economic benefit of water flooding can increase.Therefore, the rational injection production ratio and injection water allocation must be predicted depending on the rational injection production pressure gradient, production rate and adjusting value of water cut..
