Application case of intelligent drilling tool technology

Jiejiesi "Walker" Intelligent Drilling System
Application scenario: Participated in frontline oil and gas development operations such as drilling China's first 10000 meter deep well in Tarim Oilfield, Xinjiang.
Technical advantages: Integrated with various intelligent equipment and control systems, such as intelligent drilling robots, high-performance hydraulic elevators, high-performance power slips, etc. By applying AI vision, motion control and other technologies, the dual safety interlock and linkage cooperation of sensor load signals and machine vision display positions are used to solve the safety and efficiency coordination problems in automation and intelligent operation. The developed machine vision positioning system can automatically recognize the position of drilling tool couplings, enabling intelligent drilling robots to operate accurately and eliminate inefficient and error prone manual intervention.
Application effect: "One click" operation has been achieved, ensuring the inherent safety of drilling platforms through unmanned and automated operation, reducing the labor intensity of drilling workers, and improving the efficiency of lifting and drilling from the original 15-20 columns/hour to over 28 columns/hour.

Application of Intelligent Drilling Technology in TP259-2H Production Well
Application scenario: TP259-2H production well located in the west of Tarim Basin, where the buried depth of Cretaceous oil and gas reservoir is more than 4000 meters, is characterized by strong heterogeneity, thin reservoir and large structural fluctuation.
Technical advantages: independently developed azimuth electromagnetic wave resistivity imaging logging tool and 3D target precise navigation technology. Based on interdisciplinary integration and utilizing intelligent algorithms to establish multiple correlation relationships, a three-dimensional geological model of oil and gas reservoirs at the meter scale is constructed, pre drilling targets are pre-set, and horizontal well trajectories are designed; Predict geological information and oil and gas indicators. The directional electromagnetic wave resistivity imaging logging tool can transmit high-precision data in real-time to the surface decision-making system under complex underground conditions, providing parameters for well trajectory control; The pre drilling model constructed by 3D target precise navigation technology has high accuracy, and the real-time update speed of the 3D model while drilling is fast.
Application effect: It demonstrates high reliability and stability under complex working conditions such as high torque underground, horizontal pressure support, and strong vibration impact. In the end, the sandstone drilling encounter rate of TP259-2H horizontal well was 96.3%, and the tested oil and gas production was 45 tons/day, which was about 5 times that of adjacent wells. This verified the accuracy and reliability of intelligent drilling equipment technology in horizontal drilling of thin sandstone oil and gas reservoirs.

Application of CY-R236V intelligent raise drilling rig in the Duobaoshan copper mine of Zijin Mining
Application scenario: Zijin Mining Duobaoshan Copper Mine Courtyard Project, construction of two guide section return air shafts, with a diameter of 4.5 meters for the west guide section and 5.5 meters for the east guide section, reaching a depth of 100 meters, and a hard rock layer (F12 rock layer).
Technical advantages: The first intelligent equipment in China capable of constructing 6-meter diameter shafts, with full process autonomous operation, no need for manual entry into the well, efficient drilling, no need for temporary support, smooth wellbore wall, and minimal disturbance and damage to surrounding rock.
Application effect: Under the conditions of hard F12 rock layers, the eastern guide section completed the pilot hole operation in only 72 hours, and the hole expansion operation took only 158 hours. The deviation rate was less than 0.15%, and the efficiency was improved several times, significantly reducing construction costs and providing technical equipment support for improving the quality and efficiency of the mine.

Automation upgrade of old facilities drilling rig on Panyu 4-2B platform in the eastern part of the South China Sea
Application scenario: A certain adjustment well on the 4-2B platform in Panyu, eastern South China Sea, as a pilot project for the automation upgrade of old facility drilling rigs.
Technical advantages: For the first time, automated tools such as iron drills, pneumatic slips, and hydraulic elevators have been equipped. Through integrated design, the equipment footprint has been reduced and operational processes have been optimized. At the same time, a management team will be established to accurately benchmark operational efficiency, refine and formulate acceleration plans, prepare schedules, draw operational rules, collaborate with all parties to discuss and communicate, analyze and investigate influencing factors in real time, and improve equipment deployment efficiency; Organize experts and technical personnel from manufacturers to train employees and enhance their technical skills.
Application effect: The project schedule is advanced by 9 days and the speed is increased by 35%. The speed of drilling tools is increased by 30%, the efficiency of drilling and tripping is increased by 20%, and the tool combination time is reduced by 10%. The daily drilling efficiency has significantly increased to 278 meters per day, and the equivalent drilling cycle of 2500 meters has been rapidly reduced to 4.83 days, with a year-on-year increase of 29% and 59% in project goals compared to the beginning of the year. A good set of "promotable, referenceable, and replicable" samples has been formed in the field of "Youzhi" drilling and completion engineering construction.
