摘要:

中国天然气对外依存度一直居于高位，持续提升储气库调峰保供能力是确保中国天然气安全的必然选择。针对气藏断裂系统发育、储层埋藏深、非均质强、气水分布复杂等特点，经过20余年持续攻关，中国储气库在气藏型和盐穴型储气库建设与运行领域取得突破，形成5大系列技术：①库址筛选与评价技术；②库容设计与评估技术；③井筒质量高效控制技术；④大排量注采设计技术；⑤风险识别监测技术；实现了储气能力从40×108 m3到192×108 m3的跨越。未来，中国储气库库址资源品质进一步劣质化、类型进一步复杂化，逐渐向油藏、低渗气藏、盐穴复杂连通老腔、水层等新类型转变，储气库高效建设与运行将面临4大挑战：①储气地质体动态密封评价理论与技术亟待完善；②新类型储气库库容设计技术处于起步阶段；③气井产能未能充分发挥，配套技术尚需创新；④风险预警与安全管控能力尚难满足储气库安全运行的需要。建议通过专项攻关，完善地质体断层密封性弱化动力学机制，揭示油藏滚动注气排液扩容机理，明确低渗气藏分区建库注采动力学与压力空变规律，创建油藏建库、复杂连通老腔、低渗气藏、水层建库库容设计技术，形成强注强采优化设计方法，研发国产化微地震监测系统与井筒完整性检测/监测系列装备，不断拓展储气库功能新领域，建立适合未来建库目标的理论技术系列，推动储气库高质量可持续发展。
