摘　　要：为了综合考察油田地质及开发因素,保证高效开发,针对海上稠油油田注水开发的采油速度及相关指标进行理论分析。基于相渗曲线及含水率与采出程度的关系,探讨不同含水率下采油速度、年产油量自然递减率、剩余可采储量采油速度理论关系曲线计算方法。通过实例计算,观察某区块采油速度及相关指标变化规律,认为目前含水阶段实际年产油量自然递减率相比理论值偏高,剩余可采储量采油速度呈递减趋势。Oil production rate and related indicators of offshore heavy oil field through water flooding were calculated and analyzed theoretically in order to guarantee the efficiency of development. Based on the relative permeability curves and theoretical curves of water - cut vs. recovery percent, theoretical curves of oil production rate, annual oil production decline rate and oil production rate of remaining recoverable reserves under different water cut were presented. Taking one block in offshore oilfield for example, the theoretical variation of oil production rate and re- lated indicators were studied. Comparison of actual value and theoretical value showed that the actual annual oil production decline rate was higher than the theoretical value at present and oil production rate of remaining recover- able reserves tended to decrease.
