Drilling Rig Hoisting Platform Security Monitoring System Design and Application

Abstract

Drilling rig hoisting platform security monitoring system has played a very important role in oil exploration. And drilling parameters and working condition of workers are particularly important, because these parameters indicate that whether the drilling work is safe and effective directly. A security monitoring system is established to provide the real-time parameters for drilling safety is the purpose of this study. The monitoring system includes a top drive, a traveling block hook, an oil derrick and a driller room, and the controller of the system is programmable logic controller PLC. The procedure of the system is written by the RSLogix5000 software, the PC configuration is used force control monitor configuration software. According to the system, top drive, driller room and environment wind speed parameters in real-time are collected and displayed in the configuration of upper computer, the collected parameters can be used to determine the working conditions of the top drive and to send timely warnings for inspection maintenance to avoid drilling safety accidents. Work fatigue remind of driller and regularly remind of derrick check can be as much as possible to reduce safety accidents. And automatic operation of traveling block hook reached the default point faster and more smoothly than manual operation given the other uncontrollable factors in manual operation. The application of the system is successfully working in the drilling work site.

Procedure of Analysis and Digital Processing of Large Data Array in Real Time upon Intellectualization of Roller Drilling

“…Adjusting values of unpredicted perturbations in this case are determined by computer and controller, and preset variables for adaptive constituents and sensors depend on data relating to variations of physical and mechanical determinants of drilling rock. It should be mentioned that a set of random uncontrolled variables is presented by a set of effects on drilling in the form of random noises in controlling channels not subjected to highly accurate measurements [18][19][20]. Adherence to the procedure of estimation and processing of large data arrays upon intellectualization of roller drilling is based on close interrelation of drilling model variables in combination with addition of regulator in the form of intelligent system (adaptive constituent) [12].…”
