| [摘 要]近年来，全球页岩气产业迅速升温，特别是北美页岩气的快速发展改变了世界能源供应格局。我国页岩气资源潜力巨大，已经引起政府和相关企业的高度关注。页岩气储集层具有高自然伽马、低声波速度、低密度、高电阻率等地球物理特性，这些特性是页岩气勘探地球物理技术识别与评价的依据。当前我国页岩气勘探开发总体处在起步阶段，主要任务是有利目标区域的优选和资源量评价，以及开展关键技术的试验研究。本文通过页岩气地球物理勘探技术发展现状的分析，指出地球物理勘探技术作为页岩气储层评价和增产改造的关键技术，应重点在建立页岩气储层测井评价方法和标准、页岩气储层地震资料各向异性处理和多波反演技术等方面加强研究。加大页岩气勘探工作的投入，基础性研究与关键技术研发相结合，借鉴国外成功经验与自主创新研发相结合，部署开展基础性页岩气资源调查评价，探索建立适合我国地质特点的页岩气地球物理勘探评价技术体系。 |

| Abstract: In recent years, the shale gas industry has received much attention in many countries, especially the rapid development of shale gas in North America has changed the world's energy supply pattern. The huge potential of shale gas resources in China has accordingly attracted great concern of the government and related enterprises. Shale gas reservoirs are characterized by high natural gamma, low acoustic velocity, low density and high resistivity, serving as the basis for the identification and evaluation of shale gas exploration geophysical technology. The current shale gas exploration and development in our country is in its starting stage, and the main task is the optimization of favorable target areas, resource quantity evaluation and key technology tests. Through analysis of the geophysical technology development situation, it is suggested that the geophysical exploration technology is critical for shale gas reservoir evaluation and production capacity-increasing. We should focus on the establishment of shale gas reservoir logging evaluation methods and standards, as well as strengthening research of shale gas reservoir seismic data anisotropic treating and multi-wave inversion technologies. China should increase investment to shale gas exploration work, combine the basic research with the development of key technologies, combine the successful experiences of foreign countries with our own independent innovative research and development, and then deploy basic investigations and assessment of shale gas resources. We should thus establish an evaluation system of shale gas geophysical exploration suitable for China's geological characteristics. |
