RX250x900V Multi-Functional Oilfield Drilling Machine 250 tons

Main Machine

The maximum feeding / push-pull power of the RX250×900V multi-functional rig is 250 tons, which can drill inclined and straight holes with drilling angle from 12ºto 90º. This rig has foundation base, which is easy to be installed. Meanwhile, the main machine has the robot hand changing the drill rods automatically.

The whole drilling rig adopts split type layout, which is divided into: base, main machine, robot hand, power station, wellhead clamp holder, control chamber.

Main Machine Base

The rig is mounted on the base. The base should be strong enough, and easy to install.

The base consists of eight parts - in order to facilitate transport.

Foundation Base (on the top of which displays the rig), composed by two parts, length and width, respectively: 6 m and 2.5 m

Side Ramp (which is installed on the side of the base), composed by four parts, with the length of 6m and the angle of 45º.

Back and Forth Riveting Plate, composed by two parts, with the length of 7m, see the following picture: (the open file distance from the middle is 300mm)

All parts are connected with the bolts.

Automatic Device for Loading and Unloading Drill Rods

The function of the robot hand is for loading and unloading drill rods or casings. The maximum clamping diameter should be 451mm.

The role of the drill rod rack is to put the drill rods or casings in the suitable position. The length of the drill rod rack should be 8m.

The device should be able to fit all the drilling angles and should give full consideration to the bending caused by the movement of the drill rods and casings. At the same time, the safety should be ensured, the displacement such as falling down of the drill rods/casings should not be allowed. All of the safety factors should be greater than 2.

The position of the drill rods on the rack should be controlled by the means of hydraulic or electric, no manual intervention.

All the controls should be carried out in the driving room.
