摘要: 欠饱和油藏无原生气顶,存在多相流体、组分交换等现象,目前面临气液交互驱机理不清、指标设计精度偏低等关键难题。针对油藏型储气库气液交互驱、流体物性周期变化等特殊性,提出了建库关键理论技术难题,总结了近年来的关键进展并提出了未来攻关方向。研究表明,油藏建库面临气液交互排驱扩容机理与相传质作用机制的关键科学问题,以及次生气顶形成与控制、建库指标设计、高效排液扩容等技术问题;提出了水驱效率、波及效率等特殊库址筛选指标;模拟实验揭示交互驱液效率、驱油效率较单一气驱分别提高10.3和12.5个百分点,考虑相传质因素下有效库容量增加17.8%;油藏型储气库未来将围绕空间动用机理与相作用机制、建库参数设计以及次生气顶形成控制等方面深化理论技术攻关。研究成果为科学指导油藏建库设计、储气调峰和原油提采双赢奠定了基础。

Abstract: Undersaturated oil reservoirs utilized for underground gas storage are devoid of primary gas caps and are characterized by multiphase fluid coexistence and compositional exchange. Currently, they encounter critical challenges, including an inadequate understanding of gas-liquid interactive displacement mechanisms and suboptimal precision in performance indicator design. By analyzing the special characteristics of gas-liquid interaction flooding and fluid properties periodic changes in oil reservoir type UGS, key theoretical and technical challenges have been proposed. Recent key developments have been summarized, and future research directions have been proposed. Research has shown that oil reservoir type UGS faces key scientific issues, such as the expansion mechanism of under gas-liquid interactive displacement and the interphase mass transfer mechanism, as well as technical issues such as secondary gas cap formation and control, index design, and efficient liquid discharge expansion. Special site selection indicators such as water drive efficiency and sweep efficiency have been proposed in oil reservoir type UGS. Simulation experiments reveal that the interactive displacement efficiency of fluid and oil has increased by 10.3 and 12.5 percentage points respectively compared to single gas displacement. Considering the factor of phase mass transfer, the effective storage capacity increases by 17.8%. In the future, oil reservoir type UGS will deepen theoretical and technological research on mechanism of space utilization and phase interaction, UGS construction parameter design, and secondary gas cap formation and control. The research results provide important basis for scientifically guiding the UGS design, achieving peak shaving capacity, and improving the oil recovery.

Key words: oil reservoir, underground gas storage, space utilization, interphase mass transfer, secondary gas cap, displacement fluid efficiency
