The invention relates to a large-diameter engineering well casing running method. According to the large-diameter engineering well casing running method, the methods that a drilling machine is used for lifting and a cement buoyancy plug is poured into a casing are combined in a large-diameter engineering well for casing running. The large-diameter engineering well casing running method is simple, convenient to operate and small in potential safety hazard, solves the problem that drilling machine equipment is insufficient in lifting capacity in the process of large-diameter engineering well casing running, and improves construction safety and efficiency.
