How to change the down-the-hole drill rig to a water drill video

How do you drill a hole in a rig?

Put the bit on the ground and make a chalk mark, ‘0,’ on the first drill pipe against a suitable fixed point on the rig and at a known height above ground level, such as the drilling table (which centralizes the drill pipes in the hole).

How does a drill work?

A method whereby water is pumped down a string of rods by motor water pump from which it emerges as a jet that cuts into the formation. Drilling may be aided by manually rotating the drill string or by moving it up and down in the hole. Cuttings are transported up by circulating water between the drill pipe and the borehole wall.

How does a water drill rig work?

Water drill rigs use a combination of high volume varied pressure air, water and drilling mud to expel cuttings, unless want to withdraw the drill at regular intervals not much else will function and will wedge drill head in bore hole in short order. Cable tool rigs do not use a medium to flush the well. They bail out the cuttings as required.

How do you drill a hole?

Drilling may be aided by manually rotating the drill string or by moving it up and down in the hole. Cuttings are transported up by circulating water between the drill pipe and the borehole wall. The drill pipe may simply have an open end with a constructed drill bit added.

How to drill a borehole?

Once a borehole drilling has been decided and a suitable site selected, the proper drilling method must be chosen. Generally, drilling equipment consists of a mast from which the drilling components (tools, drill pipes and cable) are suspended and, in most cases the drill pipes are driven into the ground. It can be manual or powered driven method.

How does rotary drilling work?

Rotary drilling uses drilling mud (mixes of water, bentonite clays, polymers, and additives) as the circulation medium. In the rotary mud system, drilling fluid or mud is pumped down through the drill pipe and out through nozzles in the bit.
