新华社重庆12月12日电（记者戴小河、王全超）中国石化12月12日发布消息，中国石化“深地工程·川渝天然气基地”再获重要突破，涪陵页岩气田新增1213.56亿立方米探明地质储量顺利通过自然资源部审定。至此，涪陵页岩气田累计提交探明地质储量达10188.8亿立方米，成为中国石化首个万亿立方米页岩气田，为四川盆地页岩气提供了新的建产阵地，有效保障国家能源安全。

      Xinhua News Agency, Chongqing, December 12 (Reporter Dai Xiaohe, Wang Quanchao) Sinopec announced on December 12 that the "Deep Earth Project · Sichuan-Chongqing Natural Gas Base" of Sinopec made another important breakthrough, and the new proved geological reserves of 121.356 billion cubic meters in Fuling shale gas field successfully passed the approval of the Ministry of Natural Resources. So far, the cumulative proved geological reserves of Fuling shale gas field have reached 1,018.88 billion cubic meters, becoming the first trillion-cubic meter shale gas field of Sinopec, providing a new production position for shale gas in the Sichuan Basin, and effectively guaranteeing national energy security.

  此次提交的探明储量位于重庆市南川区，气藏埋深1000米至4900米，压力系数较小，是典型的常压页岩气藏，开采难度更大。华东油气分公司深化基础研究，创新常压页岩气富集高产地质理论认识，采用变密度三维采集方式让地质构造细节更清晰地刻画出来，形成了绿色高效开发页岩气井储层改造关键技术，不断突破常压页岩气效益开发技术瓶颈。

      The proved reserves submitted this time are located in Nanchuan District of Chongqing, with a buried depth of 1,000 meters to 4,900 meters and a small pressure coefficient, which is a typical normal pressure shale gas reservoir and more difficult to exploit. East China Oil and Gas Company has deepened basic research, innovated geological theoretical understanding of atmospheric shale gas enrichment and high yield, adopted variable density three-dimensional acquisition method to depict geological structure details more clearly, formed the key technology of green and efficient development of shale gas well reservoir transformation, and constantly broke through the technical bottleneck of atmospheric shale gas benefit development.

  此次新增探明储量顺利提交意味着涪陵页岩气田南川常压页岩气区块平桥构造带、东胜构造带、阳春沟构造带等三个千亿立方米增储区连片成带、实现整装探明。

      The successful submission of the new proved reserves means that the Pingqiao structural belt, Dongsheng structural belt and Yangchungou structural belt of Nanchuan atmospheric shale gas block in Fuling shale gas field have been successively formed into three billion cubic meters of additional storage areas and realized integrated exploration.

  中国具有“富煤、贫油、少气”的资源特点，长期是油气进口大国，页岩气的勘探开发对于中国能源格局具有重要战略意义。

      China has the characteristics of "rich coal, poor oil and little gas" resources, and has long been a big oil and gas importer. The exploration and development of shale gas has important strategic significance for China's energy pattern.

  中国石化于2012年底在涪陵实现勘探突破，拉开了我国页岩气商业化开发的序幕。作为我国首个实现商业开发的大型页岩气田，涪陵页岩气田于2014年3月投入商业开发，2017年如期建成100亿立方米年产能。

       Sinopec made an exploration breakthrough in Fuling at the end of 2012, which opened the prelude to the commercial development of shale gas in China. As the first large shale gas field in China to achieve commercial development, Fuling shale gas field was put into commercial development in March 2014, and the annual production capacity of 10 billion cubic meters was completed as scheduled in 2017.

  目前，涪陵页岩气田已累计生产页岩气超700亿立方米，约占我国页岩气年产量的三分之一，为长江经济带沿线6省2市、上千家企业、2亿多居民送去清洁能源，助力长江经济带高质量发展。

       At present, Fuling shale gas field has produced more than 70 billion cubic meters of shale gas, accounting for about one-third of China's annual output of shale gas, for 6 provinces and 2 cities along the Yangtze River Economic Belt, thousands of enterprises, more than 200 million residents to send clean energy, to help the high-quality development of the Yangtze River Economic belt.
