Types Of Tools For Water Well Drilling

By Daphne Bowen


In boring wells, the equipment used need to be very powerful. This way, the job will be accomplished within a short time and the depth will be sufficient. Many people want a method that is not so expensive. However, since a considerable depth is desired and the ground to be drilled may be having resistant components, the tools for water well drilling should be high standard.

The options are not that many but still the geology of the site has to be taken into account. Many of these tools have to be machine operated as opposed to manual operation. Nowadays, the available machines are advanced such that the drilling job is done very fast and the depths reached are commendable too. Machines used in boring are often times referred to as just rigs.

Jetting method of drilling wells uses pumps to direct water downward via a small nozzle in order to loosen sediments. On the return journey, the water brings with it the drilled materials and deposits it in a settling pit. The process is repeated over and over again. This drill pipes are suspended from a trivet. The tripod is hand rotated in maintaining the straightness of the hole.

A cable tool is a replacement of manual drillers which were in common use during the past. The entire equipment is referred to as just tools. Their use is in elevating and bringing down cables made from steel. A bailer removes the cuttings made. The water in the hole should be kept at a certain volume to suspend the cuttings and allow for easy removal.

The machines range from the simple powered winches suspended from a tripod to the technical pulley systems and large mast drums. The trailer or truck bed is used to mount the cable rigs using hydraulic motors in lowering and raising of mast and rotation of cables.

Mud rotary is another of this equipment. It requires a cutting bit, a considerable length of drill pipes made from steel with joints which have been threaded, a turning motor and a mast to offer support. In drilling, refinement can be achieved by mixing clay with other well construction material to enhance the mud rotary ability to lift the dirt from the borehole. The fluid resulting after the mixing process is referred to as drilling mud.

The mud rotary drilling rigs a quite a number. They are categorized into two; table drive and top head drive. The first one involves turning of the pipe used in drilling at the rig base through a rotating motion while in the second one the pipe turning is facilitated by hydraulic motor positioned at the pipe end.

In both of these categories, the superior drilling pipe has a lifting apparatus for elevation and depression and also a swivel to allow for mud to be continuously removed as the work goes on. The larger rigs are able to cover considerable ground and drill to a considerable depth. Unlike in the past, this work is completed within a very short time. This saves on time and energy for both company and the client.
