Varieties Of Tools For Water Well Drilling

By Daphne Bowen


In drilling boreholes, very powerful equipment is required. This shortens the duration taken to complete the work and also achieves a profound depth. What one should strive for is using the least expensive means but get quality services too. Tools for water well drilling should be utilized with consideration of the materials to be drilled and the desired well characteristics.

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 uses a pipe to force water to flow down a drill pump and come out through a narrow spout. This water jet leads to loosening of the sediments. As the water flows back, it takes with it cuttings to the pit used for settling. The water is then returned back to the pipe. The pipe used for drilling is hanged down from a trivet and rotated using hands so as to keep the hole straight.

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.
