After the development of oil field enters the stage of production decline, the effect of different decline law on the yield and ultimate recovery is different. Taking a strong natural water drive reservoir in foreign country as an example, using the method of reservoir engineering, this paper studies the law of production decline and reservoir development strategy during 2006–2016. Results show that the production data of 2006–2013 are accord with exponential decline, and monthly composite decline rate is 0.6%; taking the new well of N1 and changing zone well of C1 as examples describe that the development strategy of this stage is the combination of infilling wells and workover wells in mature field, totally increases 61910 Mbbl oil by putting 167 wells into production and increases 7149 Mbbl oil by conducting 45 workover wells. The production data from 2014 to 2016 in line with the linear decline and the composite decline rate are 1.9%. Prediction results show that, under the condition of linear decline, the reservoir will reach the economic limit production before the end of the contract. Therefore, the stage is mainly by new wells in the new development field and more effective workover to slow decline, totally increases 9502 Mbbl by putting 58 wells into production and increases 2419 Mbbl oil by conducting 26 workover wells. The production rate increases, and the monthly composite decline rate is −0.9%. The actual situation of field has confirmed that the production decline type in different periods and the decline rate are changing, and the corresponding development strategies are also different. The research of production decline and the development strategy have the vital significance for enhancing the level of development and improving the ultimate recovery.
