The record for the deepest well on land in Asia was broken by Sinopec's "Shendi No. 1", reaching 9,432 meters!

According to news from this site on November 15, this site learned from the Sinopec official account that today Sinopec’s “Shendi No. 1” Yuejin 3-3XC well tested in the Tarim Basin obtained high-yield oil and gas flow, with a daily crude oil production of 200 tons. 50,000 cubic meters of natural gas. The well was drilled to a depth of 9,432 meters, setting a new record for the deepest onshore well in Asia.

#The successful drilling of this well once again proves that China’s deep earth series technology has entered the forefront of the world, providing the necessary equipment to enter the 10,000-meter ultra-deep layer. Important technology and equipment reserves to ensure national energy security.

The difficulty of the "Shendi No. 1" project is rare at home and abroad. It broke two records for the horizontal displacement of Asia's deepest well and ultra-deep drilling

"Shendi No. 1" "The Yuejin 3-3XC well is located in Shaya County, Aksu Region, Xinjiang, on the edge of the Taklimakan Desert. The well depth reaches 9,432 meters, which is 584 meters higher than the height of Mount Everest. In addition to facing the problems of complex geological structure, high temperature, and high pressure in ultra-deep wells, the well is also designed with a horizontal distance of more than 3,400 meters. It faces new problems such as difficulty in running casing and the tendency of cuttings to form "cuttings beds" in the horizontal section. The construction difficulty is rare at home and abroad. The well was drilled on May 1 this year and completed on October 26 after 177 days of construction.

The Yuejin 3-3XC project is led by Sinopec Northwest Oilfield. It introduces excellent domestic and foreign technical teams, fully integrates high-quality resources and advanced technologies, and integrates the application of advanced speed-increasing tools such as long-life spin guides and high-performance drill bits. It boldly adopted new technologies to solve problems such as rock breaking and speeding up, and also made full use of big data, remote support and other means to efficiently provide risk warnings and optimize drilling parameters in real time, achieving a breakthrough transformation from "experience drilling" to "scientific drilling".

The Northwest Oilfield adopts ultra-deep large-displacement technology, allowing Well Yuejin 3-3XC to extract oil and gas from more than 7,200 meters below the Wetland Nature Reserve in the upper reaches of the Tarim River, which is several kilometers away. This technology is like magic, allowing the Northwest Oilfield to obtain oil and gas thousands of meters away. At the same time, in order to accurately find oil and gas in the "deep and dark" underground, the drill bit must be equipped with eyes. The Northwest Oilfield adopts ultra-deep, high-temperature and high-efficiency directional technology. It transmits signals at depths below 7,000 meters to the surface in real time through a high-precision measurement and control system while drilling, so that the drill bit is like having eyes and can adjust its trajectory at any time. At a depth of 7,200 meters The rapid progress underground has realized the leap from short distance to long distance and from long period to short period of horizontal wells

In addition to the Yuejin 3-3XC well, two other ultra-deep long-displacement wells have also been deployed in the same well site. Well, the engineering operations set two new records in Asia and achieved five industry-leading results. With the breakthrough of the Yuejin 3-3XC well, all three wells have achieved efficient production, with a cumulative production of 58,000 tons of crude oil, and an estimated new recoverable reserve of 310,000 tons, which has effectively utilized ecological redline areas, reservoir areas, and similar domestic oil and gas resources. Provide reference and guidance.

In recent years, 60% of the world’s new oil and gas reserves have come from deep formations. Deep and ultra-deep layers have also become the main battlefield for major oil and gas discoveries in my country. my country's deep and ultra-deep oil and gas resources reach 67.1 billion tons of oil equivalent, accounting for 34% of the country's total oil and gas resources.
