Method of connecting joints of drill pipe
A method of connecting a joint of drill pipe for rotary earth drilling having tool joint members on each end with threaded connections for connecting the joint with other joints of drill pipe is shown. Nickel plating is applied to a portion of the threaded connection of at least one of the tool joint members. The threaded connection is then doped with a zinc base thread compound and the joint of drill pipe is made up by threadedly connecting the nickel plated threaded connection of one tool joint member with the threaded connection of a mating tool joint member. The nickel plated tool joint member when used with zinc base thread compound provides a connection with desirable frictional properties at elevated temperatures such as are encountered in geothermal wells.
