摘　　要：就注水开发油藏对外合作提高采收率项目中基础油的预测方法问题进行探讨，并提出一种注水开发油藏基础油预测的建议方法，该方法以生产数据及其变化规律作为预测的基础，通过综合分析影响产量变化的因素达到预测基础油的目的，弥补了产量递减曲线分析方法将产油量作为总项进行预测的局限性和不足，使处于不同开发阶段的油藏都能应用本方法作基础油预测，该方法可操作性强，易于协商取得双方满意的结果，促进合作谈判的顺利进行。The basis oil predicting is discussed in the paper to jointly cooperate on enhancing oil recovery in the waterflooding reservoirs and a new method of forecasting the basis oil is put forward. The method is based on the production data and its change rule, thus reaches the purpose to predict the basis oil through comprehensively analyzing the factors affecting the production, fetches up the limitation and shortage of production decline curve method in which, the oil production is recognized as the overall item. The basis oil at different development stages can be predicted by this method, it is applicable and easy to meet the needs of both sides and promote the negotiation of cooperation.
