The drilling rig is the main machine to complete the drilling construction. It drives the drilling tool and drill bit deep into the formation, and completes the auxiliary work of lifting and lowering the drill tool and casing, extracting the core, and replacing the drill bit through the elevator (winch) on the drilling rig. The main function of the pump is to deliver flushing fluid into the hole to clean the bottom of the hole, cool the drill bit and lubricate the drilling tool.
