Abstract: The calculation of economic reasonable and economic limit well controlling reserves is very important for reservoir development and adjustment, which relates to reservoir characteristic, technologies and economic conditions. Based on the principle of calculating well spacing density of onshore oilfields, the method is deduced and validated for calculating economic reasonable and economic limit well controlling reserves, with considering development practical situations of offshore oilfields.

Key words: offshore oilfield, well controlling reserves, calculation method, formula derivation

摘要： 海上油田的经济合理和经济极限单井控制储量与油藏特性、开采工艺、经济条件等因素密切相关,用科学的方法确定经济合理和经济极限单井控制储量,对于指导油田开发和调整具有非常重要的意义。文中基于陆上油田通常研究的经济合理和极限井网密度分析原理,提出和推导了基于海上油气田开发投资条件下的单井控制储量分析与计算方法。
