摘要：

塔里木盆地走向深层领域，油气藏的复杂性和高投资成本给经济开发带来了极大的挑战。从油气藏成藏、成储角度出发，重点总结了深层油气成藏条件、储集空间类型、储集体内部结构和烃组分变化4个维度的复杂性和特殊性，深入讨论了目前制约深层油气藏高效动用、提高采收率、开发经济性的3个核心问题及其对策，由此提出解决这些核心问题的4个攻关方向：①近源“生输储盖”组合下的油藏特征预测方法；②深层缝洞保存的量化参数表征方法；③分隔缝洞体边界及内部连通性表征方法；④建立超深层领域全生命周期经济评价体系和差异化开发策略。上述的思考和对策为高效开发深层、超深层碳酸盐岩油气藏、保障国家能源安全提供了借鉴性的意见和建议。

Abstract:

The economic development of oil and gas reservoirs in the Tarim Basin is challenged by their complex nature and substantial investment costs. This paper primarily summarizes the intricacies of deep oil and gas reservoirs across four dimensions: accumulation conditions, reservoir space types, internal structures, and changes in hydrocarbon composition. It also explores three core issues that hinder efficient utilization, enhanced recovery, and economic growth of these reservoirs, along with proposed countermeasures. To address these challenges effectively, the paper proposes four research directions: ①A prediction method for reservoir characteristics that integrates the processes of near-source generation, transportation, storage, and cap rock formation. ②A quantitative parameter characterization method for identifying deep fractures and preserving caverns. ③A characterization method for differentiating fracture boundaries and assessing their internal connectivity. ④The establishment of a comprehensive life cycle economic evaluation system for ultra-deep domains, alongside differentiated development strategies. These strategies offer valuable suggestions towards achieving efficient development of deep to ultra-deep carbonate reservoirs and ensuring national energy security.
