摘　　要：不同驱动类型油藏其生产气油比的变化特征不同,基于生产气油比保持不变和下降这两种情况,推导建立了一种新的广义模型,并能简化成为目前在溶解气可采储量预测中已广泛应用的累计产油量与累计生产气油比关系曲线法和累计产油量与累计产气量关系曲线法,实际应用表明,与前述两种简化前的预测方法相比,该广义模型的适用性更强。The reservoirs with different displacement processes have different characteristics of producing gas-oil ratio. In this paper, a generalized model is established based on the characteristics of producing gas-oil ratio. It is demonstrated that the relation between cumulative oil and cumulative gas oil ratio and the relation between cumulative oil and cumulative gas can be obtained from a simplification by this prediction model. Compared with the two methods, the generalized model in this paper is more adaptable or applicable.
