中国页岩气资源开发利用的可行性评价

论文以可行性评价为切入点,从资源与赋存条件、综合开发利用条件、环境安全性及市场前景四方面因素选取了19 项指标,构建中国页岩气开发可行性评价指标体系,采用中、美对比研究方式,评价中国近期进行页岩气大规模开发利用的适宜性问题。研究表明:①市场需求、成本与价格、核心技术条件、含气量、水资源污染、水资源供应及政策支持等指标是影响页岩气开发的关键因素;②对比得分结果显示,中、美页岩气开发可行性等级分属中度偏下与中度偏上区间,得分差距较大;③中、美页岩气开发可行性值的差距,主要归因于两国在页岩气资源与赋存及综合开发利用条件方面的巨大差异。鉴于目前两国页岩气开发的实际情况,得分结果与现实具有较高符合度。

Feasibility Evaluation for Exploitation and Utilization of China Shale Gas Resources

As a kind of clean, efficient and high-quality unconventional natural gas resources, exploration and development of shale gas can effectively enhance the proportion of natural gas in China's primary energy consumption structure, to improve energy structure and ensure energy security. In this paper, we took the feasibility evaluation as a starting point. An evaluation index system consisting of 19 indicators in terms of the resources and occurrence conditions, comprehensive exploitation and utilization conditions, environmental safety and market prospects influencing exploitation suitability of shale gas has been established based on comprehensive consideration of China shale gas development. Making Sino-US comparison study, we explored the suitability issues on China's recent large-scale exploitation and utilization of shale gas. The main conclusions are as follows: Firstly, some indicators such as market demand, cost and price, core technical conditions,gas content, water pollution,etc., are key factors affecting the development of shale gas. Secondly, comparison score results show the feasibility of development of shale gas in the two countries respectively belongs to moderate downward range and moderate upward range, with a great scoring gap being respectively 0.49971 points and 0.74159 points. Thirdly, great scoring gap between the two countries is mainly due to the huge difference in resources and occurrence conditions, comprehensive exploitation and utilization conditions. From the present shale gas development situation in China and the United States, the results coincide with reality to a higher degree.
