摘要:

通过对全球861个深层油气田储量、产量分布及近10年来的勘探发现和开发实践进行分析,揭示了全球深层油气藏的分布领域及形成的基本地质特征,预测了深层油气勘探潜力、理论与技术发展趋势。研究表明:目前深层大油气田发现个数、总储量和产量占全球比例总体上还较低,但近10年来的勘探发现展示了深层油气良好的发展前景。深层油气田主要发育在被动陆缘、前陆冲断带、克拉通区中下组合和裂谷盆地深层等领域。深层油气勘探及地质理论研究揭示深层油气的独特石油地质特征,其油气生烃特征突破了传统的油气消亡线,扩大了"油气窗"赋存范围;深部由于超压、深水重力流砂体沉积、碳酸盐岩生物礁发育、次生白云石化、裂缝发育和岩溶等多种作用而发育优质储层,突破了传统储层的"死亡线";盐岩发育及变形控制深层油气聚集及盐相关圈闭发育。未来,深部储层预测、超压预测、深层钻井、完井改造和测井技术发展将推动深层油气的勘探开发。

Abstract:

Through analyzing the reserves, production distribution, exploration discoveries and development practices of 861 deep oil and gas fields worldwide in the past decade, this study reveals the distribution and basic geologic characteristics of global deep hydrocarbon reservoirs, and predicts the deep hydrocarbon exploration potential as well as theoretical and technological development trend. Research results show that the number, total reserves and production of the discovered large deep oil and gas fields account for a low proportion of the global total, while exploration discoveries in the past decade reveal a favorable development prospect in deep reservoirs. Deep oil and gas fields are dominantly developed in passive continental margins, foreland thrust belts, middle-lower assemblages of cratons and deep reservoir of rift basins, etc. Special petro-geologic characteristics of deep hydrocarbon are revealed by studies of deep hydrocarbon exploration and geology theories, i.e., hydrocarbon generation breaks through the conventional hydrocarbon extinction line to expand the occurrence of "hydrocarbon windows". Under the action of overpressure, sand sedimentation by deep-water gravity flow, carbonate reef development, secondary dolomitization, fissure development and karst, etc., favorable reservoir beds are developed in deep layers, which go beyond the conventional "extinction line" of reservoir beds. Deep hydrocarbon accumulation and salt-related trap development are controlled by salt rock development and deformation. The future development of technologies, such as deep reservoir prediction, overpressure prediction, deep drilling, well completion and stimulation, and well logging, will promote deep hydrocarbon exploration and development.
