The calibrator is used to expand and equalize the diameter of the borehole at a certain depth. This is necessary to create an even and stable well surface, especially before installing casing or in preparation for further drilling.
Residue and contaminant removal:
CLS helps remove mud residue, cuttings, rocks and other contaminants that can interfere with normal operations or damage equipment.
Blockage prevention:
It prevents clogs during the drilling process by providing permeability for drilling mud and other working fluids to maintain normal flow and efficient circulation.
Eliminating unevenness:
The paddle design of the calibrator can effectively eliminate borehole wall irregularities and defects, which improves the quality of work and reduces the possibility of damage to drilling tools or pipes.
Working principle of KLS calibrator:
Paddle design:
The calibrator is equipped with blades that are arranged in a spiral pattern. As the tool passes through the borehole, the blades “push out” the borehole walls, expanding the borehole to the required diameter and leveling the surface.
Drilling fluid circulation:
The tool's working elements actively circulate the drilling fluid, which also helps clean sediment from the borehole walls and prevent clogs.
Operation during drilling:
Typically, the calibrator is used during drilling to maintain the borehole diameter or before installing casing to ensure proper fit.
Advantages of using the CLS spiral paddle calibrator:
Accurate borehole alignment: Provides accurate calibration and alignment of the borehole diameter, which is especially important before installing casing and to ensure stability of further operations.
Contaminant Removal: Effectively removes contaminants such as drill cuttings, rocks, rust and other debris from the borehole walls, preventing equipment damage.
Prevent clogging: Maintains normal mud flow and prevents clogging, which is important for proper system operation.
Extends equipment life: Eliminates irregularities and defects in the borehole wall, which reduces stress on drilling equipment and tubing, extending their life.
Versatility: Can be used in various stages of drilling and in different types of wells.
EQUIPMENT TYPE: CONVENTIOANAL DRILLING AND SIDETRACK TOOLS
