摘　　要：对目前常用的产量自然递减类型判断方法进行了研究,并根据Arps产量递减理论及油田实际生产数据,对各种方法进行了评价,通过实例说明了综合判断法具有较好的可行性。同时将油田产量自然递减率分解成产液量自然递减率和含水上升因子2个主要部分,分析了产液量和含水对产量自然递减率影响所占的比例,并预测了开发指标。This paper studies the methods of common use to determine production decline type,such as graphic cut and trial,curve shift methods.The author appraised the different methods to determine the type of decline base on the study of Arps's production decline theory and the actual production data of the oilfield.The existing example indicates that this synthesis study has preferable feasibility.Meanwhile,the author divides the oilfield production decline rate into the liquid production rate natural decline and the water cut escalating factor and analyzes the liquid production rate and the water cut influence degree of the natural production decline rate,finally forecasts the exploitation indexes.

关 键 词：递减类型判断 递减率 含水率 产液量 指标预测
