陆相中低熟页岩油富集与原位转化科学问题及关键技术

Scientific Problems and Key Technologies of Enrichment and In-situ Transformation of Mid-low Mature Shale Oil in Continental Facies

围绕第281期双清论坛主题,本文回顾了陆相中低熟页岩油富集与原位转化研究现状,从陆相页岩油概念与类型、富有机质页岩形成机理、原位转化反应与传热机制、原位转化流动机制与原位开发技术五方面总结归纳了近年来的主要研究进展。从陆相有机质超量富集的环境响应与地质模型、陆相有机质超富段母质结构、能量场与产出物构成和固、液、气相有机质多相态、多场耦合流动机理三个方面归纳了关键科学问题与技术需求,并提出了五方面研究面临的难点和挑战,梳理了未来研究重点方向和国家自然科学基金资助的目标。

Based on the 281^(th)Shuangqing forum,this paper reviews the research status of enrichment and in-situ conversion of continental mid-low mature shale oil,and summarizes the main research progress in recent years from five aspects:the concept and type of continental shale oil,formation mechanism of organic rich shale,in-situ conversion reaction and heat transfer mechanism,in-situ conversion flow mechanism and in-situ development technology.This paper puts forward the key scientific issues and technical requirements from three aspects:environmental response and geological model of excessive enrichment of continental organic matter,parent material structure of ultra-rich section of continental organic matter,composition of energy field and products,and multiphase and multi field coupling flow mechanism of solid-liquid-gas phase organic matter,and propose five research difficulties and challenges,and the future research direction and the key objectives of National Natural Science Foundation of China.
