On April 26, Chuanqing Drilling Changqing Drilling Corporation 40,623 drilling team used the PDC bit developed and manufactured by the company in the construction of the 22-22 well in the horizontal well in Heshui District, Gansu Province. The shortest drilling cycle was rewritten to 1.875 days, which accelerated the drilling of regional horizontal wells.

After the establishment of the tool R&D center, the company independently developed new tools such as casing suspension, hydraulic oscillator, horizontal well electrical protection joints, and personalized PDC drill bits to create high-end tools for drilling speed.

In 2014, the company successively developed more than 60 types of PDC drill bits of 4 types, used in directional wells and horizontal wells in Gandong, Shaanxi, Shaanxi and northern Shaanxi, collected data, summed up experience, and proposed amendments. At the beginning of this year, in order to improve the rock breaking efficiency of the drill bit, the drill crown curve and the bit structure were optimized, the drill bit related parameters were improved, and 20 PDC drill bits were manufactured. In April, six wells, such as directional wells and horizontal wells, in the Jidong block of Gansu, were tested. Among them, Zhenxu 17-31 well achieved an average mechanical drilling rate of 25.76 m / h, and achieved an average mechanical drilling rate of 33.83 m / h in the town 195-57 well, and other wells drilled a single drill bit from 1800 m to 2000 m. .

As of May 11, the 40423 well in Guping, which was constructed by the 40,623 drilling team, had a depth of 2,772 meters and a drilling cycle of 10.38 days. "I am very proud to be able to use the drill bits produced by my company to create a horizontal well construction record and boost the horizontal well drilling speed," said Li Xiuming, captain of the 40623 drilling team.
