我国页岩气开发向世界亮出“家底”

2017-09-04 07:06:00   中国经济网

能源矿产是人类赖以生存和发展的重要物质基础,地球页岩层内的天然气资源与常规天然气可采储量相当的发现,让人为之振奋。美国的页岩气革命、加拿大的页岩气开发成功,促进了全球能源结构的调整和改变,影响着世界能源生产与消费格局的深刻变化。

“我国页岩气开发虽然起步较晚,却已成为继美国、加拿大之后,第三个形成规模和产业的国家。”国内最早研究页岩气的专家之一、国土资源部矿产资源储量评审中心主任张大伟表示。日前,作为“十三五”国家重点图书、国家出版基金项目,“中国能源新战略——页岩气出版工程”向世界最大出版商之一的施普林格·自然集团输出英文版权,预计5年内陆续向全球发行。这意味着,我国页岩气向世界亮出“家底”。

页岩气是一种清洁高效能源,自2009年以第一口页岩气资源战略调查井掀开页岩气勘探序幕、2010年我国产出第一立方米页岩气开始,我国页岩气开发就驶入了快车道——从2012年的1亿立方米到2014年的12.47亿立方米,再到2016年的78.82亿立方米,位居世界第三位,实现了量和质的飞跃。根据我国《页岩气发展规划(2016―2020年)》,我国力争2030年实现800亿至1000亿立方米。

事实上,我国页岩气探明地质储量高达5441.29亿立方米,按可采储量计算,目前可达世界第一。截至2016年,全国页岩气矿业权达54个、17万平方公里,成为我国未来发展页岩气的基础和前沿“阵地”。此外,通过技术引进、消化吸收和技术攻关,我国已经掌握了页岩气地球物理、钻完井、压裂改造等技术,具备3500米以浅水平井钻井及分段压裂能力,初步形成适合我国地质条件的页岩气勘探开发技术体系。

说到底,我国开发页岩气的重要性和紧迫感源自国家能源安全与环境保护的现实。加快我国页岩气开发能够直接增加天然气供应、优化能源结构、缓解减排压力、保障能源供应安全、提高能源利用效率、拉动油气装备制造业发展、带动基础设施建设,以及培育相关产业新的经济增长点。

多位专家表示,虽然我国页岩气勘探开发起步不久,在推进过程中不可避免地面临一些困难和挑战,但在吸收国际同业经验、吸取已有教训的基础上,我国页岩气开发从高起点出发步入正轨,已具备了绿色开发的技术基础和能力,对其广阔发展前景具有足够理由表示乐观期待。(经济日报记者 牛 瑾)
