摘要
面对非常规油气规模快速发展引发的全球能源行业诸多重大转变,亟需深入思考非常规油气革命对经典石油天然气地质学理论的深刻影响,重新审视油气成藏要素地质概念和油气系统理论框架,赋予石油天然气地质学新时期全新的学科内涵。基于此,总结了近期全球非常规油气勘探开发的重大进展,指出非常规油气革命不仅具有油气资源大幅增加的经济意义,而且对石油天然气地质学理论带来重大革新,因此具有重要的科学意义。归纳了经典石油天然气地质学生烃、储集层、分布和开发等4方面的理论核心内容,全面回顾了石油天然气地质学理论发展历史中的5个重要节点,包括背斜与圈闭理论、有机质生烃与油气系统理论、陆相油气地质、海洋深水油气地质、连续型油气聚集与非常规油气地质理论。非常规油气对经典石油天然气地质学在圈闭、储集层、盖层、资源分布、富集规律等基本理论概念方面产生了重大突破,推动油气地质基础研究向全过程生烃、全类型储集层、全成因机制、全种类油气资源转变,深化非常规油气地质理论研究,推动石油天然气地质学理论体系发展与重构,对中国乃至世界油气从常规向非常规战略发展具有重要意义。
Great changes of the global energy industry have been caused by the rapid development of unconventional oil and gas. It is necessary to deeply consider the profound influence of the unconventional oil and gas revolution on the classical petroleum geological theory and to review geological conception of oil and gas accumulation elements and theoretic framework of petroleum system, giving the petroleum geology a new academic connotation. The author summarizes the significant progresses of global unconventional oil and gas exploration and development, and points out that the unconventional oil and gas revolution not only has a significant economic significance of oil and gas resource increment, but also brings great innovation to the theory of petroleum geology, thus having important scientific signiflcances. This paper summarizes the core contents of four aspects of hydrocarbon generation, reservoir, distribution and development in classical petroleum geology, and comprehensively reviews the five important nodes in the developmental history of petroleum geology, which include anticline and trap theory, hydrocarbon generation from organic matter and petroleum system theory, continental petroleum geology, marine deepwater petroleum geology, continuous hydrocarbon accumulation and unconventional oil and gas geological theory. Unconventional oil and gas has made a great breakthrough to classical petroleum geology on the basic theoretical concepts such as trap, reservoir, caprock, resource distribution, and enrichment, thereby promoting the basic research on petroleum geology to transform into the whole process of hydrocarbon generation, whole type of reservoir, and whole genetic mechanism, deepening unconventional petroleum geology theory, promoting the development and reconstruction of petroleum geology system, representing great significances to the strategic development from conventional to unconventional oil and gas in China or even in the world.
