Deepwater drilling rig

The rock powder generated during the drilling of deepwater wells is flushed out of the hole by a mixture of wind and water gas. The mixed gas is injected into the impactor through the center of the drill rod by the powder discharge mechanism, and then enters the bottom of the hole through the gas groove on the impactor cylinder body The vehicle has a low center of gravity, making climbing smoother and safer, with strong adaptability. It adopts a new hydraulic technology, which has a large turning torque, smooth and fast propulsion and lifting. The control panel and operating handle are centrally controlled, making the operation simple. The operator can stand on the side of the main engine for drilling operations, improving the safety factor of the operation The high-speed rotation of the impactor inside the hole is achieved by a separate rotating mechanism, namely an electric motor or pneumatic rotating device outside the hole, through a drill rod connected to the rear end of the impactor The main technical parameters of this product (LQ-300 deep water well drilling rig) are as follows: maximum drilling depth of 100m-300m, maximum drilling diameter of 300mm, drill rod length of 2000mm-3000mm, maximum stroke of power head of 4600mm, drill rod diameter of 89mm/108mm, lifting force of 25T, rotary torque of 10000NM, bearing method: hydraulic track type, walking speed of 3000km/h, climbing ability of 30 °, external dimensions of 3000mm * 1700mm * 230mm, and overall weight of 7000kg
