On the basis of Arps fundamental production decline law, a simple and reliable analysis method of production decline was presented, and the linear relationship between cumulative production rate and time in log coordinate system was developed.

• Arps基本的递减规律出发；提出了一种新的简单可靠的分析产量递减的方法.；该方法在对数坐标中建立了累积产量与时间的线性关系
