The invention relates to a drilling
well control parameter intelligent
monitoring system which comprises a monitoring part for
drilling fluid cycling volume, a monitoring part for
drilling fluid inlet and outlet flow, a monitoring part for
drilling fluid inlet density, outlet density, drilling temperature, outlet
natural gas, and H2S concentration, a monitoring part for
wellhead pitshaft flowing
fluid level and table torque, and a collection instrument part. All the signals are transmitted into the collection instrument to be collected through an RS485 network cable; after
data processing is carried out, the data is transmitted to a
drill floor parameter
display device and a central
station host computer through a
wireless data transmission device; the data storage, display and print are carried out by the host computer, and the data is simultaneously uploaded into a
data platform processor of an upper-level
command center; finally,
remote control realtime
processing and monitoring are carried out on all the
well control parameters of all the drilling crews. The intelligent
monitoring system has the beneficial effects of realizing omnibearing, long-distance and timely drilling
well control, safe production, and playing better role in preventing the occurrence of accidents such as well kick, loss circulation, blow-out, etc.
