（彭博社）“为了寻求超深层天然气储量，中国今年第二次开始在地下钻探一个万米深的洞。

据新华社报道，中国石油天然气集团公司周四开始在四川省钻探神地川科1井，设计深度为10,520米（6.5英里）。该项目是继中石油集团五月份在新疆开始钻探的一口类似规模的井之后进行的，当时被称为中国有史以来最深的井。

据新华社报道，虽然早期的井被描述为实验性井，该项目旨在测试钻井技术并提供地球内部结构的数据，但四川项目正在寻求寻找超深层天然气储量。

四川拥有中国一些最大的页岩气储量。然而，由于地形崎岖和地下地质复杂，中国国有石油巨头在挖掘潜力方面只取得了有限的成功。

近年来，在一系列电力短缺、地缘政治冲突和全球价格波动的情况下，中国政府向能源公司施加压力，要求其通过提高国内产量来加强燃料安全。

(Bloomberg) – China has begun drilling a 10,000-meter hole in the ground for the second time this year as it seeks ultra-deep reserves of natural gas.

China National Petroleum Corp. on Thursday began drilling the Shendi Chuanke 1 Well in Sichuan province, with a designed depth of 10,520 meters (6.5 miles), Xinhua News Agency reported. The project follows a similar sized well that CNPC began drilling in Xinjiang in May, described at the time as the deepest ever undertaken in China.

While the earlier well was described as experimental in nature, with the project designed to test drilling technologies and provide data on the Earth’s internal structure, the Sichuan undertaking is seeking to find ultra-deep reserves of natural gas, according to Xinhua.

Sichuan is home to some of China’s largest shale gas reserves. The nation’s state-owned oil giants have had only limited success tapping their potential, though, because of difficult terrain and complicated underground geology.

China’s government has put pressure on energy companies in recent years to enhance fuel security by boosting domestic production amid a series of power shortages, geopolitical strife and global price volatility.
