China has seen a new technological breakthrough at an ultra-deep well on the edge of the Taklimakan Desert in northwest China by setting a new daily drilling record of 2,006 meters, the China National Petroleum Corporation (CNPC) said on Wednesday.
The announcement came as drilling work was completed at the “Ha 13-H9” well in the Tarim Oilfield, located in Shaya County of Aksu Prefecture, Xinjiang Uygur Autonomous Region, reaching a final depth of 7,341 meters. The daily record was achieved earlier during the drilling process at this site.
The record is attributed to the considerable developments made in key technical equipment, including high-strength drill pipes, high-temperature-proof drilling fluid that can withstand heat of up to 220 degrees Celsius, and logging tools capable of operating thousands of meters below the surface.
These advancements have provided essential support for developing deep-earth oil and gas exploration in China.
Since the beginning of this year, the CNPC has accelerated the drilling speed of the wells in the Tarim Oilfield, and the drilling cycle has shortened by more than 20 percent. The record for daily drilling speed for digging ultra-deep wells in China has been broken multiple times.
