发明名称 METHOD OF DISTINGUISHING BETWEEN INSTALLING DIFFERENT SUCKERRODS
摘要 A self-contained mobile repair unit for repairing wells includes the hydraulic and pneumatic tooling required to do a variety of jobs including the installation and removal of an inner pipe string, sucker rods and a pump. The repair unit, hydraulic tooling and pneumatic tooling share a common engine and a common process monitor. An extendible derrick supporting a hoist is pivotally coupled to the frame of the repair unit. Access to data gathered by the monitor is restricted at the job site itself. Instead, the data is transmitted to a remote home base for the purpose of monitoring operations from a central location.
