China News Service, Chengdu, December 1st (Li Xinyu Zhou Mi) On December 1, news came from PetroChina Chuanqing Drilling Chuandong Drilling Company: the highly anticipated "national weight"-one-click human-computer interaction automation The first well drilled by the drilling rig, Well H62-4 in the Wei 204 shale gas block, was successfully drilled to 5320 meters, which was completed 6.78 days earlier than the target period.
It is reported that the one-click human-computer interaction 7000m automated drilling rig is known as the "national weight" in the field of national drilling engineering. It is currently the most advanced domestic drilling rig independently researched and developed. It is at an advanced level in the international drilling rig industry. One of the top ten scientific and technological innovation achievements.

According to reports, the one-button human-computer interaction is to realize the compound linkage, cross operation, and seamless connection of multiple equipment of the drilling rig through a single button, which reduces auxiliary work time and improves work efficiency.
The overall lifting of the drilling rig has been upgraded from the original drawworks to the ground remote control hydraulic cylinder lifting, which greatly improves the intrinsic safety and lifting speed. Each well can reduce the auxiliary operation time by 2-3 days. The drilling rig has also obtained 10 invention patents. , Has a milestone significance in the history of my country's drilling equipment.
The Wei 204H62-4 shale gas well drilled by the rig started on September 30 and completed on November 26.
In the construction operation of Well Wei 204H62-4, the drilling rig achieved the deepest "three trips and one trip" in this block, the fastest mechanical drilling rate, the longest horizontal section, the shortest rotary guided drilling cycle, and the reservoir drilling encounter There are many records such as 100% penetration rate and target penetration rate.
According to the relevant person in charge of PetroChina Chuanqing Drilling Chuandong Drilling Company, the company will conscientiously record, analyze, evaluate, and evaluate drilling rig tests, forming a complete set of automated drilling rig operating procedures, and promoting them throughout the country. .
