In order to solve single function, low field adaptability, low integration level and other problems of the existing drilling safety protection device and monitoring operation technology in China, an intelligent protec?tion system for drilling safety monitoring is developed. The system is integrated with automatic and intelligent protec?tion?Field application testing results show that, the system can perform drilling pump pressure protection, traveling block protection, real?time monitoring of overflow and lost circulation, qualitative and intelligent automatic mud injection, real?time display of drilling parameters and curves and other functions to minimize risks arising from ab?normally high drilling pump pressure?It has protected the travelling block from collision more than 1 000 times and reached the accuracy rate of 100% to avoid overflow accidents arising from failure of timely mud injection in the trip?out. Successful application of this system has reduced oil drilling risks to protect life and property safety, indi?cating the drilling safety protection technology enters a new controllable stage.
