Common engineering rig types and working principle
First, the impact drill The vertical reciprocating motion of the drill causes the drill bit to impact the bottom of the well to break the rock formation. The structure is simple, there is no circulation washing system, and the removal of cuttings and the drilling machine cannot be performed at the same time, so the efficiency is low. Drilling depth is generally within 250 meters, sometimes up to 500-600 meters. There are two main types: 1. tophammer drill rig . Use the weight of the drill itself to impact the formation. The lower end of the drill is several sharp-angled flaps that can be folded. When the drill moves downward under its own weight, the flap opens and cuts into the rock layer, and then the drill is lifted by the winch through the wire rope, and the flap is closed. During the process, the cuttings are caught in the cone, and the cuttings are discharged from the wellhead. The drilling depth is usually 40 to 50 meters, and the deepest is 100 to 150 meters. 2. wir...
