China completed the deepest vertical well drill in Asia

Shenditake 1 is a scientific exploration project. In addition to searching for oil and gas resources, this well is also aimed at promoting research on Earth’s evolution and deep geology.

This is the deepest vertical well in Asia and ranked second in the world. The project also achieved a number of other technical breakthroughs globally, including the deepest pouring of cement pipes, performing the most deepest drilling measurements, and the fastest 10,000 m drilling on the soil. Immediately.

The drilling process started on May 30, 2023, with the first 10,000 m to be completed in 279 days, about 1,000 m finally took more than 300 days. During this process, the project team observed signs of operating oil and gas.

According to Wang Chunsheng, experts from China National Oil and Gas Group, each meter at such a depth posed many challenges. “The team has overcome many obstacles, including heavy loads, unstable wells, worn drill bits, malfunctioning tools, loss systems,” he said.

Wang also emphasized that they successfully drilled through 12 geological systems of the Tarim basin, finally reaching the stone layers to create high quality oil and gas in the middle of 10,851 m and 10,910 m. “This is the first time in the world discovered oil and gas more than 10,000 meters deep in the mainland, significantly expanding the scope of super -deep petroleum exploration,” he said.

Shenditake 1 is equipped with the first 12,000 m automatic drilling rig in the world, developed by China. Using core patterns, stone pieces and measurement data, the team has created the first 10,000 m geological records of Asia, providing important data for deep earth exploration activities and oil research. gas.

“Shenditake 1 well has overcome a series of challenges, including huge depth, high temperature, high pressure, and successfully perform both scientific exploration and oil detection tasks. This achievement helps help Promoting significant progress in technical technology, ”said He Jiangchuan, Vice President of Petrochina Company, said.
