中石油完成亚洲最深直井钻探

中国石油天然气集团公司(CNPC)在中国西北沙漠中成功钻探亚洲最深直井,井深达 10,910 米。该井位于新疆维吾尔自治区塔里木盆地塔克拉玛干沙漠腹地,被称为深地塔克 1 号井,是一个科学勘探项目。

塔里木盆地拥有巨大的深层油气储量,其两侧是天山和昆仑山。然而,由于其地表条件恶劣、地下结构复杂,塔里木盆地也是勘探难度最大的地区之一。据中石油称,钻探于 2023 年 5 月 30 日开始。钻探 10,910 米用了 580 多天,其中一半以上的时间(约 300 天)花在了最后的 910 米上。

该井已穿透 12 个地质构造,最终到达了可追溯到 5 亿年前的岩层。在地表以下 10,000 米处,温度超过 210 摄氏度,足以蒸发食用油。压力超过 145 兆帕,大于马里亚纳海沟最深处的压碎力。

CNPC completes drilling of Asia’s deepest vertical well

China National Petroleum Corporation (CNPC) has completed the drilling of the deepest vertical well in Asia, as a borehole reached a depth of 10,910 m in China’s northwestern desert. Located in the heart of the Taklimakan Desert in the Tarim Basin, Xinjiang Uygur Autonomous Region, the well, known as Shenditake 1, is a scientific exploration project.

The Tarim Basin contains vast, deep-seated oil and gas reserves that are flanked by the Tianshan and Kunlun mountains. However, it is also one of the most challenging regions to explore due to its harsh surface conditions and complex underground structures. According to CNPC, drilling began on 30 May 2023. It took over 580 days to complete the 10,910-m drilling, with more than half of the time — some 300 days — spent on the final 910 m.

The well has penetrated 12 geological formations, ultimately reaching rock layers that date back over 500 million years. At 10,000 m below the surface, temperatures exceed 210 degrees Celsius, which is hot enough to vaporize cooking oil. Pressure surpasses 145 MPa, greater than the crushing forces found at the deepest point of the Mariana Trench.
