摘要
根据海上丛式井网整体加密调整的高难度挖潜和高投入等特点,建立了可采储量、采收率增加值、单井可采增加值、含水率、平均年增油速度、初期产能六项评价指标的评价体系,并在模糊评判等方法的基础上提出了基于开发规律指标和调整方案指标评价相耦合的"二元评判法"。通过实际油田的应用,二元评判法是一种易实施、较为客观全面的评价海上油田井网调整加密调整效果的新方法。
According to the characteristics of difficult potential tapping and high investment in overall encryption adjustment of offshore oil field, evaluation indexes system of adjustment effect was established, including recoverable reserves, increase of oil recovery efficiency, increase of single well recoverable reserves, water-cut, ratio of average oil increment per year and initial productivity. Based on the method of fuzzy evaluation, the two-element evaluation method coupling the evaluation system of water-flooding effect and reservoir comprehensive adjustment effect was put forward. The two-element evaluation was applied in an actual oil field. The results indicated that the method can be easy to implement, and more objectively and comprehensively evaluate overall encryption adjustment effect of offshore oil field.
