In a remarkable display of technological prowess, China has set a new record for onshore drilling by achieving a daily drilling depth of 2,006 meters, according to the China National Petroleum Corporation (CNPC) on Wednesday.
The groundbreaking achievement took place at the "Ha 13-H9" well in the Tarim Oilfield, located on the outskirts of the Taklimakan Desert in Shaya County, Aksu Prefecture, within the Xinjiang Uygur Autonomous Region. The well reached a final depth of 7,341 meters, with the daily drilling record accomplished during the intense drilling phase.
Experts attribute this milestone to significant advancements in key technical equipment, including the deployment of high-strength drill pipes, high-temperature-resistant drilling fluids capable of withstanding temperatures up to 220 degrees Celsius, and sophisticated logging tools designed to operate thousands of meters below the earth's surface.
These innovations have been pivotal in supporting the development of deep-earth oil and gas exploration across China.
Since the beginning of the year, CNPC has accelerated drilling activities in the Tarim Oilfield, reducing the drilling cycle by over 20 percent. This has led to the daily drilling speed record for ultra-deep wells in China being broken multiple times, highlighting the country’s commitment to enhancing its energy exploration capabilities.
