The Research & Application Of Drilling Monitoring And Controlling Hardware System

Drilling monitoring and controlling system is the key to monitor, analyze and decide the drilling process. The scientific principals of"safe, optimized and balanced drilling"and the customs'higher requisitions for drilling instruments accelerate the development of drilling monitoring and controlling systems. The electronic technique, computer and the communication revolutions make the development possible. These days, the drilling monitoring and controlling system is changing from mechanical, hydraulic meters to digital, integrated, intelligent and networked ones.This paper is based on the open projects of the National Lab of Science drilling–the Research& Application of Drilling Monitoring and Controlling System.In this paper, the author, aiming at the drilling instruments at home and abroad, referencing the advanced techniques, discusses the monitoring and controlling theory thoroughly, and develops a drilling monitoring& controlling system with high precision, complete and reliable function, conveniently operation, beautiful and friendly interface.This system use the distributed data gathering system to monitor the drilling parameters such as drilling pressure, pump pressure, rotation rare, drilling rate, pump rate of flow and hook-load. Also it can control the drilling pressure, rotation rare and pump rate of flow.This system fully utilizes up-to-date technology, and this drilling monitoring and controlling system represents a new heights of success. It also establishes a good basis for the next step to research the automation drilling instrument.
