The purpose of a tricone drill bit
Tricone bits are widely used in the well-drilling industry, the purpose of a tricone drill bit is to go into the ground and get to things like crude oil deposits, usable water, natural gas deposits, etc. Crude oil can be deep inside hard formations of rock, so a tough bit is needed to get down to it. When drilling for water, the drill bit makes fast work of the hard rock in the way and gets to the water below more efficiently than any other tool. Tricone bits will work for any type of rock formation whether it is hard, medium, or soft, but depending on the material being drilled through, they can drill through clay, shale, limestone, etc, and also go through hard shale, mudstone, calcites, etc. you’ll want to pay special attention to the type of tooth on the bit and seals to make sure you are staying safe during use.
Four different types of tricone drill bits.
1. Standard Roller Tricone Bit
Standard Roller is an open bearing used for shallow water as well as oil and gas wells. It is important to note that the open roller bits are less expensive to manufacture, and therefore less expensive to you.
2. Sealed Roller Tricone Bit
Sealed Roller bit is protected a little better with a protective barrier around it making it great for digging wells.
3. Sealed Journal Tricone Bit
Sealed Journal is used for drilling oil as it has the hardest face and can stand up to more.
4. Air Blast Bearings
Air Blast Bearings are equipped with Air Circulation Bits and these tricone bits have air passages that supply air to the bearings for cooling and lubricating the bearing, and for cleaning the bearing from the drilling debris.
How does a tricone bit break the rock?
The way the tricone breaks through the rock is by using its multitude of very small chisel shape teeth, which protrude from a roller. These are pushed into the rock by the rods that connect it to the surface, and the weight is distributed evenly to break through. Like most things, there are some limitations to the use of each tricone bit, which can sometimes be hard to control when hitting an extremely hard rock that the tricone isn’t meant for. However, when the correct bit is used it should have no problem breaking through, so make sure to check the IADC codes list before you settle on buying one for your job.
Remember when choosing the right type tricone bits for your job, you need to take into consideration the type of job you will be doing, and the type of rock you will be going through. Learn everything you can about the job before you choose a type of bit and you will be on the right track.
In short, the right tricone bit helps make the majority of drilling jobs faster and easier, but only if the right bit is in use. Each bit type works best for a different job, but tricones are generally very versatile in what they can handle – as long as you know the parameters of your job and the specs of what you’ll be digging through, it should be easy to select a suitable bit from the list of options.
In addition, Tricone bits are also used to make holes for foundations, and are often used for this type of job after the bit have been drilling for oil or something else for a while – the construction industry often opts to use recycled bits in order to construct their foundations in a less expensive way.
