摘　　要：根据递减理论,论文进一步深化了几种常用自然递减率表达式地基本含义及认识,研究了不同递减规律下递减率计算方法之间的联系与区别,推导出了年产量递减率、年产能递减率、月递减率三者之间的相互关系。根据上述关系式及其递减规律,能够快速而简捷地进行递减率指标预测,从而确定年度分月产量运行安排或开发生产规划安排,能有效地指导油田开发生产管理。Based on decline theory, the meaning and knowledge of the expressions of different decline rates is further deepened, the relationship and differences among different calculation methods under the condition of different decline rules are studied, and some relations among annual oil production decline rate, annual productivity decline rate and monthly decline rate are derived finally. With these relations and their decline regulation, decline rate could be forecasted rapidly and easily so as to confirm the arrangement of monthly production of each year and development program, guide the management of oil field development and production.
