    • 摘要: 页岩层系内的非常规油气已成为全球油气勘探开发的热点,这些资源的形成与富有机质页岩密切相关,形成演化有序、空间分布上共生。目前的研究通常按非常规油气类型单独进行,尚未从页岩层系整体角度考虑各类油气资源的分布规律。在大量调研国内外页岩层系油气资源分布规律的基础上,提出页岩层系油气资源有序共生,并以鄂尔多斯盆地长7页岩系为例进行解剖,按照成熟度阶段、埋藏深度和有机质丰度,将长7页岩层系油气资源分成露头-浅埋藏油页岩区、中等成熟-中等埋深压裂页岩油区、中等成熟-中等埋深原位改质页岩油区、高成熟度-深埋页岩气区和紧邻-夹层致密砂岩油五大区域。基于页岩系统油气资源有序共生关系,提出页岩层系油气资源立体勘探开发的观点,以期对页岩层系非常规油气资源有效利用提供新思路。

       

      Abstract: Shale system contains abundant unconventional oil and gas resources and has become a hot area of exploration and production. This system includes such resources as shale oil and gas, tight oil and gas, and oil shale. These unconventional resources are related to the organic-rich shale and are in orderly accumulation along with the maturity and coexistence in space. However, there is a blank in the systematic study of unconventional resources. Based on the shale system, the authors studied the world's oil and gas resources distribution and put forward the argument of the shale oil and gas resources orderly accumulation and coexistence in the shale system. Taking Chang 7 shale formation of Ordos basin system as an example, the authors used the shale oil and gas resources orderly accumulation method and divided the Chang 7 shale system resources into outcrop oil shale, moderate buried depth fracturing shale oil, moderate buried depth ICP shale oil, large buried depth shale gas and tight oil areas. Based on this understanding, the authors suggest stereoscopic exploration and development in the shale system, which will provide guidance for oil and gas resources exploration and development in the shale system.
