Roller reamers are essential tools used in the oil and gas industry for boring operations. Their primary function is to cut through earth formations and enlarge the borehole to the desired size during well drilling operations. This is particularly important when the drill bit wears out and becomes under-gauged, as roller reamers can then be used to restore the hole to its original size.
However, even with new drill bits, roller reamers are still employed to cut through formations. This is because drill bits do not always create a true borehole, and there may be slight lateral shifting that occurs during the drilling process. This shifting can leave behind ledges and other distortions that need to be corrected.
In addition to their cutting function, roller reamers also serve as stabilizers to keep the drill stem centered at the specific position of placement. By maintaining the drill stem centered, roller reamers help to minimize unintentional hole-angle directional drilling. This is a significant benefit, as it helps to ensure that the drilling operation is carried out safely and efficiently.
Overall, roller reamers play a crucial role in the oil and gas industry by providing accurate and reliable boring operations. They are essential tools that help to ensure the success of well drilling projects, and their importance cannot be overstated.
Vigor's Roller Reamer is an efficient bottom-hole assembly reaming and torque-reducing tool. It provides reaming action for improving borehole shape size and quality. It also provides stabilization action by centralizing the BHA, minimizing down-hole vibrations preventing the BHA from resting on the low side of the deviated hole, and minimizing BHA fatigue. Torque reduction results from touching the formation with a set of rollers spinning around their axes as a result of the rotation of the central body.
