CCTV News: Recently, in the hinterland of the Tarim Basin, my country's deep-ground project has made a major breakthrough, and the first over 10,000-meter exploration well - Deep-ground Tarim Lai 1 completed the drilling task. With a vertical depth of 10,910 meters, the Deep-Grade Taco 1 not only set a drilling miracle in Asia and the world's second, but also marks the entry of China's Deep-Grade resource exploration into the "10,000-meter era".

Intelligent control system realizes the full process of drilling operations

The 82-meter steel giant tower is equivalent to the height of a 24-story building. This world's first 12,000-meter deep well automated drilling rig is equipped with the largest domestic power 6,000-horsepower drilling winch. The 900-ton lifting system can easily lift two EMUs, and its intelligent control system realizes the automation of the entire drilling operation process.

The pipe string automation processing system equipped with this drill rig realizes seamless connection from drilling rod to drilling through the coordination of the robot arm and intelligent algorithm. The drilling monitoring system it is equipped with is like an "electronic eye" installed tens of thousands of meters underground, transmitting 48 key parameters such as underground temperature and pressure in real time.

The ground vanguard Ultra-high temperature and high pressure drilling equipment cluster

The drill bit cannot be used, and oil and gas will not be released. To drill 10,910 meters underground, you need to drill through 12 sets of strata in the Tarim Basin. The properties of the formations change rapidly. Some formations are soft and sticky like gums, while others are hard and crispy like fruit candies, which require different types of drill bits to drill.

The person in charge of the drilling drill bit manufacturer in Deep-Taco 1 well said that the diamond drill bit used to drill a deep well of 10,000 meters is made of diamond composite sheets at a high temperature of 1500 degrees Celsius and at extreme conditions of 80,000 atmospheric pressure. This pressure is equivalent to the pressure generated by 8 elephants weighing up to 10 tons standing on the area of ​​a fingernail at the same time. After experiencing technology introduction and R&D upgrade, domestic production has been achieved.

High-strength core drill bits, drilling fluids that can withstand ultra-high temperature and ultra-high pressure, the world's first 10,000-meter ultra-high temperature logging instrument... Relying on the "weapons" of technology, engineering and technicians overcome the risks of drilling tool breakage, well leakage, formation collapse, etc., and cultivate an independent and controllable key core technology system of 10,000-meters, allowing China's deep-domain engineering to achieve a leap from equipment following to technology-led.
