There is no fixed tooth shape and bearing for the rock reamer, so it is necessary to select appropriate tooth shape and bearing structure according to different stratum structure. It adopts the palm back tilt, cold inlaid anti - ruin gold design, with the roller anti-peeling structure, mainly to prevent the roller falling off after the roller bearing is damaged, resulting in the accident in the hole. The roller reamer is suitable for horizontal directional drilling construction, with high design strength, good wear resistance, long service life and good safety performance. The reaming size is 220~1600mm.
A Rock Reamer is typically used when the borehole needs to be enlarged after the initial drilling phase. Common scenarios for reamer use include:
Increased Wellbore Diameter: When the initial drill bit creates a smaller-than-needed hole.
To Clean and Smoothen the Hole: Reaming is often done to clean the wellbore and smooth out any irregularities, ensuring better tool performance in later stages.
Directional Drilling: When drilling at angles or horizontally, reaming ensures a more stable and consistent hole.
Hard Rock Drilling: When dealing with particularly tough geological formations, Rock Reamers help ensure consistent and efficient hole enlargement.
Wellbore Integrity: Horizontal and directional wells often experience challenges like irregularities in the borehole shape, formation damage, and potential for collapse. Rock Reamers help improve the wellbore's structural integrity and ensure that the hole is large enough to accommodate casing, completion tools, or production equipment.
Efficient Hole Enlargement: In horizontal and directional drilling, where the drilling angle and path change throughout the process, the need to enlarge the borehole consistently is crucial. A Rock Reamer can be used to enlarge the hole to the required diameter while reducing the risk of hole collapse in deviated wells.
Reduced Drilling Time and Costs: Horizontal and directional drilling often require multiple reaming passes to achieve the desired borehole size. By using an effective Rock Reamer, operators can reduce the need for multiple reaming runs, which significantly lowers drilling time, labor costs, and the overall risk of tool failure.
