摘　　要：递减曲线法是天然能量开采油田进入稳定递减期后常用的一种可采储量计算方法。本文针对GQ油田滚动勘探开发、建产周期长、年产油量呈稳定或上升趋势、无稳定连续的递减期等特点,根据递减法原理,通过计算不同时间单元的可采储量并叠加求和,求得该油田的可采储量。计算结果与油田开发现状匹配较好,对其他类似油田具有借鉴作用。Decline curve method is commonly used for calculating the recoverable reserve of the oilfield exploited with natural energy that’s in steady decline period.The annual oil production of GQ oilfield using progressive exploration and development has reflected the stable or climbing state.According to the principle of decline curve,calculating the recoverable reserve of GQ oilfield by summing the recoverable reserve of different time unit.The calculated result inosculates with development status.It could be a reference for other similar oil-fields.
