摘要: 高含水关井是油田开发后期的重要措施,研究其界限对油田开发后期调整具有重要作用。从油田上常用的甲、乙型曲线和西帕切夫曲线出发,推出了相应的微分方程形式,建立了含水预测方法,与传统公式相比,运用该方法更能掌握含水指标随时间变化的详细过程,从而预测含水率等开发指标;并预测了喇萨杏油田不同经济条件下高含水井数及变化趋势,从分析油层非均质性引起的层间含水差异入手,以分层预测为基础,给出了油田关井界限计算方法。

Abstract: Oilfield has entered to extremely high water-cut stage, while water-cut continually going up, proportion of high water-cut wells increases rapidly. To shut in high water-cut well is needed in later oilfield development period, although it is a systematic project, involving problems about subsurface, surface and economic benefit. A predicting formula for number of high water-cut wells is set up to predict the variation trend of the quantity in different economic conditions. Starting from analysis on interlayer water-cut differences caused by reservoir heterogeneity, calculation method for shut-in limit of oil well is provided based on stratification prediction.

Key words: shut-in limit of oil well, high water-cut, prediction model, economic evaluation, developing adjustment
