摘　　要：将Arps递减曲线与技术经济学原理相结合,研究了加密井单井控制可采储量下限的计算方法,在考虑投产年的计产时间与评价期内产量递减规律的基础上,运用投资净现值法,推导了不同经济条件下单井增加可采储量下限的解析表达式,分析了不同经济条件与单井增加可采储量下限的关系,建立了单井增加可采储量下限与单井投资、油价、成本、开采时间、递减率及投产年计产时间的定量关系,可为单井个性化加密可行性分析提供可靠依据。Based on the combination of Arps decline curve and economics fundamentals, the method to calculate the lower limit of single infill well controlled recoverable reserves is studied. With the consideration of the production time at the year putting into production and production decline rules during the evaluation period, and with the application of investment NPV method, the expression for the lower limit of incremental recoverable reserves of single well under various economic conditions is deduced. The relation for recoverable reserves increase for single well under different economic conditions is analyzed, and the quantitative relationship between the lower limit of recoverable reserves increase for single well and single well investment, oil price, cost, production time and decline rate has been established. The research can make the feasibility analysis about the individual infilling for single well more reliable.
