On the morning of May 1, 2023, at the edge of the Taklimakan Desert in Shaya County, Aksu Prefecture, Xinjiang, China's first key oil and gas project in deep-ground engineering, Well Shendi No. 1 Yuejin 3-3, was officially drilled.

Well Yuejin 3-3 has a design depth of 9,472 meters, which will break the record for the deepest well in Asia and provide core technology and equipment reserves for China to enter the 10,000-meter-deep well. According to the plan, the well can be drilled to the predetermined location after 170 days.

Shendi No. 1 is a major project in the field of deep earth exploration in China. It is located in the Shunbei Oil and Gas Field in the Taklamakan Desert. Currently, there are 49 ultra-deep wells with a vertical depth of more than 8,000 meters, including Shendi No. 1 Yuejin 3-3 well. Xu Mingyou, Manager of the Northwest Project Management Department of Sinopec Jianghan Petroleum Engineering, said that when the well depth reaches 9,000 meters, the temperature at the bottom of the well usually reaches 200°C, and the formation pressure exceeds 150 MPa. Among the 13 indicators that measure the difficulty of drilling in the world, there are 7 in the Tarim Basin. number one.

Chen Zongqi, deputy general manager of Sinopec Northwest Oilfield Company, introduced that through innovative research, a set of world-leading complex ultra-deep formations, wellbore structure design, supporting technologies and standard specifications have been formed, and breakthroughs in China's key core technologies have been achieved. From 280 days three years ago, it has dropped to the current minimum of 97 days, and the accuracy has increased from 60% to 90%.

The Tarim Basin, where Shendi No. 1 is located, currently has 160 wells with a vertical depth of more than 8,000 meters, with proven resources of more than 5 billion tons. The known ultra-deep oil and gas resources rank first among all major basins in the country.

It is understood that 60% of the world's new oil and gas reserves come from deep formations, deep formations, and ultra-deep formations, which have become the main areas for major oil and gas discoveries. The oil and gas resources in the Tarim Basin at 6,000 to 10,000 meters accounted for 83.2% of the total respectively. % and 63.9%.Editor/Ma Xue
