"Deep di 1" leaps into 3-3 xc well The well uses HPE PDC drills and large torque, which solves the problem of poor pdc drilling and easy pdc failure. The well adopts HPE company to solve the problems such as strong abrasiability and difficult feeding in the deep formation of the ultra-deep well. The 593.7mm large-size mixed drill bit of HPE company was used to solve the problem of low gravel footage in the middle of the artesian well group, and realized the drilling through of 28m thick gravel layer. Yuejin 3-3XC oil and gas well is an oil and gas well deployed by Sinopec in Shunbei oil and gas field of Tarim Basin. It is located in Shaya County and the edge of Taklimakan Desert in Aksu Region of Xinjiang. The well is expected to drill at a depth of 9,472 meters, setting a new record for the deepest oil and gas well in Asia. When the well is 9,000 meters deep, the bottom temperature usually reaches 200 degrees Celsius, and the formation pressure is above 150 mpa. The Tarim Basin ranks first in seven of the world's thirteen measures of drilling difficulty.
