中、美页岩气开发现状的对比与思考

Shale gas development in China and US: Comparison and thinking

通过对中、美页岩气开发的资源基础、地质条件、开发技术等方面的对比,认为当前中国页岩气开发具有资源基础较好、勘探开发技术起点较高的有利因素,但也存在地质及地表条件相对差、技术尚未成熟、配套不完善等不利因素。针对这些实际情况,需要解决核心区优选、研发和优化等适合中国地质条件和地表条件的开发工程技术系列,发展"工厂化"作业模式等关键技术,以克服诸多客观因素带来的不利影响。

Through a comparison between China and US in shale gas resource, geology, development technologies and other aspects, it is shown that the shale gas development in China is characterized by favorable resource bases and high starting point of both exploration and development technologies, in addition to the positive policy support from government. On the other hand, much attention has been paid to environmental protection from the government and enterprises as well. However, there are still some negative factors, such as relatively poor geological and surface conditions, immature technical series and assistant technologies. Therefore, for the actual situation, some key technical issues must be resolved to overcome the adverse aspects caused by these actual factors and realize commercial shale gas development in China. These technical issues include core- zone optimization, development and optimization of engineering technology series which are applicable to specific geological and surface conditions, development of＂gas-factory＂operation mode, etc.
