【摘要】 非常规天然气资源主要包括煤层气、页岩气、水溶气、天然气水合物、无机气、浅层生物气及致密砂岩气等。中国非常规天然气资源潜力巨大,具有广阔的开发前景。随着经济和技术条件的改善,它们将逐渐转化为常规天然气。通过对中国非常规气成藏条件的分析,结合国外勘探开发和产量预测经验,预测了中国非常规天然气的资源前景及未来的产量趋势。中国非常规天然气资源量为200×1012～380×1012m3,远远超过了现今的常规天然气储量;15～20a后,煤层气和致密砂岩气将逐渐转化为常规天然气;30～50a后,页岩气和水溶气将成为常规天然气的重要组成部分;50～100a后,甲烷水合物将会成为天然气勘探开发的重点。更多还原

【Abstract】 China has the characteristics of a large quantity of unconventional natural gas resources showing great prospects for development. With the better economic and technical conditions,unconventional natural gases,i. e. ,coalbed methane,shale gas,solution gas,gas hydrate,inorganic gas,shallow biogas and tight sandstone gas,will gradually be regarded as conventional natural gases. Based on analyzing the accumulating conditions of the unconventional gases and the experiences of foreign exploration,development and production forecast,resources prospect and the future production trends of unconventional natural gases were forecasted in China. The volume of unconventional natural gases resources is about 200 × 1012 to 380 × 1012 m3,far exceeding today’s conventional natural gas amount in China. Coalbed methane and tight sandstone gas will turn into conventional gas in 15 to 20 years. Thirty to fifty years later,shale gas and solution gas will be the key parts of the conventional gas. Gas hydrate will be gradually playing an important role in natural gas exploration and development in 50 to 100 years.更多还原
