摘要
近年来,全球页岩油探明资源量和产量持续上升,成为重要接续资源。针对中国页岩油勘探开发现状与资源潜力,提出加快推进实现页岩油规模开发的建议,这对于保障中国能源安全意义重大,并将对全球能源经济和石油工业产业产生深远影响。中国勘探开发领域实现了非常规油气对经典石油天然气地质学理论的突破,发展了全油气系统理论,长水平井、多级压裂、夹层型页岩油开发关键技术等;提出当前页岩油勘探开发在基础理论、关键技术、效率成本、持续发展等方面仍面临一定挑战。分析指出:①中国页岩油勘探取得积极进展,具有巨大潜力,要进一步加大页岩油勘探开发支持力度;②基础理论突破是页岩油开发的关键,重点夯实理论基础有助于深化对页岩油成藏机理、储层特性、流动规律等方面的认识,为开发技术创新提供科学依据和指导;③成本控制与效率提升面临双重挑战,应充分借鉴美国的经验,结合自身特点,探索适合中国国情的发展模式,以实现效率和成本的最优平衡;④通过勘探开发一体化、地质工程开发经济一体化、全生命周期管理、提高原油采收率、储层管理、产量分配以及储量评估等措施,提升页岩油产业的持续发展能力。中国页岩油已进入规模化开发阶段,随着勘探开发的不断推进,页岩油将成为保障国家能源安全的重要支撑。
In recent years,the proven reserves and production of global shale oil have continuously increased,becoming an important subsequent resource.Considering the exploration and development status and resource potential of shale oil in China,this paper proposes that accelerating the large-scale development of shale oil is not only of great significance for ensuring China's energy security,but also will have a profound impact on the global energy economy and the petroleum industry.China has made breakthroughs in unconventional oil and gas geological theories,formed the whole petroleum system theory,overcame long horizontal well drilling,multi-stage fracturing,and the key technologies of interlayer shale oil development;and pointed out that the shale oil exploration and development still face certain challenges in fundamental theories,key technologies,efficiency costs,sustainable development,and other aspects.①The shale oil exploration in China has achieved positive progress and prove that it has immense potential,it is necessary to further increase support for shale oil exploration and development;②Breakthroughs in fundamental theories are crucial for shale oil development,and a solid theoretical foundation will help deepen the understanding of shale oil accumulation mechanisms,reservoir characteristics,and flow patterns,providing scientific basis and guidance for technological innovation in development;③Facing the dual challenges of cost control and efficiency improvement,we should fully learn from the experience of the United States based on our own characteristics,and explore a development model that adapts to China's national conditions,so as to achieve the optimal balance between efficiency and cost;④By integrating exploration and development,integrating geology,engineering,and economics in development,adopting full lifecycle management,enhancing oil recovery,managing reservoirs,allocating production,assessing reserves,and other measures,enhance the sustainable development capacity of the shale oil industr
