The invention discloses a 
petroleum drilling 
machine integrated control virtual 
simulation operating system. According to the 
petroleum drilling 
machine integrated control virtual 
simulation operating system, a display screen is connected with an 
image processor through a display screen communication network, one circuit of the 
image processor is connected with an external expanding monitoring communication network, and the other circuit of the 
image processor is connected with the external expanding monitoring communication network through a 
system graphic 
workstation; the 
system graphic 
workstation is connected with a host exchanger and the host exchanger is respectively and simultaneously connected with the external expanding monitoring communication network, a main / assistant driller control communication network and a PLC control 
station communication network; the main / assistant driller control communication network is connected with a main driller graphic 
workstation, an assistant driller graphic workstation and an industry monitoring graphic workstation; the PLC control 
station communication network is connected with a main driller monitoring PLC 
station, an assistant driller monitoring PLC station and a redundancy PLC 
intelligent control station, and the main driller monitoring PLC station and the assistant driller monitoring PLC station are connected with a main driller control chair and an assistant driller control chair respectively. The 
petroleum drilling 
machine integrated control virtual 
simulation operating system achieves highly-integrated integration drilling control.
