Full-Process Visual Control Technology for Solids Control System of Ultra-Deep Wells

The drilling rigs in China have developed from mechanical， DC drive and AC variable frequency drive rigs to today's automated and smart rigs. The demand for ultra-deep well and extra-deep well drilling rigs increases year by year. To meet the needs of drilling fluid treatment capacity of ultra-deep well drilling rigs， the solids control system is equipped with more and more drilling fluid tanks， equipment and valves， and the operation becomes more and more difficult. Moreover， the existing solids control system mainly relies on manpower to conduct equipment operation， valve shut-off， process control， operating condition inspection and state monitoring. To address this issue， a full-process visual control system for solids control system was developed to achieve a full-process automated， visual and digital centralized control. The system has the functions of remote automatic switching of processes such as metering， purification， mixing and circulation， feedback of equipment operation status， and automatic monitoring and alarm of processes. The industrial application in oil fields at home and abroad shows that the automated solids control system reduces the labor intensity of operators， improves the work efficiency， and changes the current situation of low automation of solids control system. The research results provide reference for improving the automation level of drilling equipment in China.
