CNPC announced on September 24 that China has successfully drilled qiulin 220-8-H1 well in The Jinqiu Gas Field in Sichuan province with a rotary geosteering drilling system developed by China.
For the first time, the system is equipped with a proprietary drill bit, which is equipped with navigational equipment to locate underground oil and gas resources. The system can withstand temperatures of 150 degrees Celsius and pressures of 140 mpa underground, with a 98% penetration rate. Its successful operation also marks a breakthrough in the industrial application of horizontal drilling technology and equipment for unconventional oil and gas exploration in China.
