在中国地质调查局近日召开的页岩气资源调查评价座谈会上,《地球》记者了解到,在中央高度重视,国土资源部和国家发改委等部门的强力推进下,我国页岩气勘查开发工作逐步展开,中央、地方和企业加大投入,获得了重要突破和发现。截至2014年12月底,累计投资230亿元,完成二维地震21818千米,三维地震2134平方千米,钻井780口(其中,调查井197口,直井探井238口,水平井345口),铺设管线235千米。全国共设置页岩气探矿权54个,面积17万平方千米,相继在四川长宁、威远、井研—犍为,重庆涪陵、彭水,云南昭通,贵州习水和陕西延安等地取得重大突破和重要发现,获得页岩气三级地质储量近5000亿立方米,其中涪陵区块探明地质储量1067.5亿立方米。2014年生产页岩气13亿立方米。
At the forum held recently by the China Geological Survey to investigate and evaluate shale gas resources, Earth Reporter learned that with the great attention of the Central Government and the vigorous promotion of such departments as the Ministry of Land and Resources and the National Development and Reform Commission, the shale gas exploration and development work in China Gradually expand, the central government, local governments and enterprises to increase investment, access to important breakthroughs and discoveries. As of the end of December 2014, a total investment of 23.0 billion yuan has been completed, completing 21818 km of 2D earthquakes, 2134 km2 of 3D seismic, drilling 780 wells (including 197 wells for survey, 238 wells for straight wells and 345 wells for horizontal wells) Pipeline 235 km. A total of 54 shale gas prospecting authorities have been set up in the country with an area of 170,000 km 2 and major achievements have been made in Changning, Weiyuan, Jingyan-犍, Chongqing Fuling, Pengshui, Zhaotong in Yunnan, Xiushui in Guizhou and Yan’an in Shaanxi Breakthroughs and important discoveries have resulted in the attainment of nearly 500 billion cubic meters of shale gas geological reserves, of which proven geological reserves of 106.75 billion cubic meters in Fuling block. In 2014, it produced 1.3 billion cubic meters of shale gas.
