Provided is an intelligent safe and efficient drilling automatic control system and method. The system comprises a drilling machine driving parameter detection module, a rotary drilling parameter detection module, a drilling machine control module, a drilling machine pump station, a drilling machine rotating device and a drill rig. The system can automatically detect the torque T, the thrust F1, the lifting force F2, the drilling depth L, the drilling rod rotating speed omega and the drilling speed Nu in the drilling process, automatically transmit the detected key parameters to the drilling machine control module, optimize the drilling rod rotating speed and the drilling speed and transmit optimization results to the drilling machine pump station which drives the drilling machine rotating device to conduct drilling. By means of the system and method, the stress condition of the drill rig in a hole is detected in real time, based on the stress changing condition of the drill rig in the hole, the system can timely and automatically adjust the rotating speed omega and the drilling speed Nu of the drill rig, and therefore it is guaranteed that the drill rig in at the best working condition in the hole, in-hole accidents such as drill jamming, drill breaking, drilling gas combustion and the like are reduced, and safe and efficient drilling is facilitated.
Description
technical field [0001] The invention belongs to the technical field of drilling engineering, and in particular relates to an intelligent, safe and efficient drilling automatic control system and a control method. Background technique [0002] Coal bed methane (coal mine gas) is a hydrocarbon gas that exists in coal seams and coal-measure formations. It is a harmful gas that threatens the safety of coal mine production and increases the greenhouse effect of the atmosphere. It is also a high-quality clean energy. my country's ground well pre-extraction of coal seam gas is limited by geological conditions, investment costs and other factors, and is only applicable to a few mining areas. The underground gas extraction method is the inevitable development of my country's gas prevention and utilization. trend. Drilling construction technology is the key to underground gas drainage. Drilling depth and efficiency determine the scope and progress of gas drainage, and indirectly affec...
