非常规油气资源发展现状及关键问题

我国非常规油气资源非常丰富，加快对其的开发利用对确保国家能源安全具有重要的战略意义。为此介绍了我国煤层气、油砂、油页岩、页岩气、天然气水合物、致密砂岩气等非常规油气的资源状况，分析了国家对非常规油气资源的战略需求。结论指出，为加快我国非常规油气资源开发利用步伐，需对以下非常规油气领域的关键科学问题开展攻关：油砂成矿规律及提高分离效率基础研究、油页岩成矿规律及原位开采基础研究、页岩气成藏机制及高效开采基础研究、致密砂岩气成藏机理及开采基础研究、天然气水合物成藏富集规律及开采工艺基础研究。

The present status and essential points of developing the unconventional hydrocarbon resources in China

There are large reserves of unconventional hydrocarbon resources in China and how to quicken the pace of recovering them will contribute most to meet the energy demands, thus playing an important role in the state energy security. Through a brief introduction to the reserves estimates and recovery status of unconventional hydrocarbon resources including coalbed methane, tar sands, oil shale, shale gas, gas hydrates, and tight sand gas, this paper analyzes the strategic needs of these alternative energy resources. To meet the big energy demands, we suggest a series of extensive and intensive fundamental studies as follows to help tackle key problems of exploiting and utilizing the unconventional hydrocarbon resources: tar reservoiring mechanism and how to improve its separation efficiency, oil shale origins, its regular patterns and its in situ recovery, shale gas reservoirs and their EOR technologies, tight sand gas and its recovery methods, and gas hydrate accumulation and its extraction technology.
