Design Of Oil Drilling Rig Automatic Drilling Simulator Virtual Prototype

Due to the increase of complex formation and drilling depth,in the drilling process,the drilling pressure is always changing.In order to ensure drilling quality,save drilling cost,must make reasonable adjustments to the drilling speed.With the improvement of control technology and the application of AC motor variable frequency,Drilling pressure automatic drilling technology be expanded step by step.Drilling pressure is the control object of Automatic drilling system,through the real-time detection of drilling pressure,the analysis of computer calculation,and a set of variable frequency speed control system and brake system to adjust the drilling speed quickly.In order to improve the drilling quality,reduce the cost of drilling,and improve the.drilling efficiency.Through the research of the automatic drilling system,learn the strategy of automatic drilling.Establish a three-dimensional model of automatic drilling simulation test bench,.Anysis every part of the system.Through the Simulink module to analysis the automatic drilling process in simulation.Siemens S7-200 PLC as the main control element,make a drilling pressure measurement program,inverter control procedures and the hydraulic control loop.This paper designs an automatic drilling control system experiment platform,and checked some parts which forced.
