我国陆相页岩油勘探开发进展、挑战及对策

Progress,Challenges and Countermeasures in the Exploration and Development of Continental Shale Oil

我国国内石油对外依存度居高不下,但常规石油增储上产难度大,函需寻找新的石油接替资源。借鉴美国通过页岩油气革命实现能源独立的经验,近年来,我国页岩油勘探开发和理论技术都取得了可喜进展。我国页岩油以陆相为主,发育多套岩相组合、矿物组成类型,具有时代跨度大、岩相变化快的特点。页岩油勘探开发也面临着地质理论、工程技术、管理政策等方面的挑战。建议加强陆相页岩油富集机理的理论研究、加大页岩油钻完井和压裂技术攻关,出台支持页岩油勘探开发的配套政策。

Our domestic petroleum dependence rate is very high,but it is very difficult to increase conventional petroleum production in our country,and it is urgent to find new petroleum replacement resources.Referring to the experience of the United States in realizing energy independence through the shale oil revolution,we have made gratifying progress in the exploration and development of shale oil and in theory and technology in recent years.However,Chinese shale oil is mainly continental,with multiple sets of lithofacies assemblages and mineral composition types,and has the characteristics of a long span of time and rapid change of lithofacies.Shale oil exploration and development also faces challenges in geological theory,engineering technology,management policy and other aspects.Therefore,it is suggested to strengthen theoretical research on enrichment mechanism of continental shale oil.Increasing the drilling and completion of shale oil and fracturing technology;we will introduce supporting policies to support shale oil exploration and development.
