采油速度与产能建设关键指标匹配关系

Matching Relationship among Key Indices of Production Rate and Productivity Construction

在油田开发年度计划方案编制中,产能贡献率、产能到位率、产量递减率、采收率和采油速度等是确定储量、产量和产能的关键指标。根据新建产能区块投产初期产量和产能之间的关系,基于指数型、双曲型和调和型3种产量递减方程,结合采收率指标,建立了原油开发年度计划关键指标匹配关系,并分析了产能贡献率、产能到位率、初始递减率、递减指数以及采收率等参数对采油速度的影响。建立的采油速度与产能建设指标匹配关系式为油田开发年度计划关键指标的合理取值奠定了理论依据,此方法也可用于年度或中长期规划产量和产能的优化部署。

During annual oilfield development plan making, productivity contribution rate, productivity implementation rate, production de-cline rate, recovery factor and production rate are the key indices to determine reserves, production and productivity. According to the rela-tionship between initial production and productivity of brought-in blocks, based on exponential, hyperbolic and harmonic equations of pro-duction decline and combined with recovery factor indices, the paper establishes a matching relationship among the key indices of annualoilfield development plan making, and analyzes the influences of productivity contribution rate, productivity implementation rate, initial de-cline rate, decline exponent and recovery factor on production rate. The established relationship could provide theoretical basis for reason-able selection of the key indices of annual oilfield development plan and can be used for production and productivity optimization duringannual or mid-long tern planning.
