Details about the diamond reaming shell:
Diamond Impregnation: The diamond reaming shell is manufactured by embedding diamond particles onto its surface through a process called diamond impregnation. The diamonds used are industrial-grade and have exceptional hardness and durability.
Cutting Mechanism: As the diamond reaming shell rotates, the embedded diamonds come into contact with the rock formation being drilled. The diamonds act as cutting elements, grinding and wearing down the formation to enlarge the borehole.
Enlarging and Smoothing the Borehole: The primary function of the diamond reaming shell is to enlarge and smooth the borehole. By continuously cutting into the formation, the shell gradually increases the diameter of the hole while maintaining its integrity.
Borehole Stability: The diamond reaming shell plays a crucial role in stabilizing the borehole. It helps prevent the collapse and deviation of the hole by ensuring a consistent and well-defined path during drilling operations.
Flushing and Cooling: The design of the diamond reaming shell allows for efficient flushing and cooling of the drill bit. This helps to remove drill cuttings from the borehole and maintain optimal drilling performance by preventing heat buildup.
Core Sample Retrieval: The diamond reaming shell enables the extraction of core samples from the drilled formation. Core samples provide valuable information about the geological properties, such as rock composition, porosity, and permeability. These samples aid in reservoir characterization and decision-making during drilling and exploration processes.
Versatility: The diamond reaming shell is compatible with various drilling assemblies and can be used with different types of drill bits, including PDC (polycrystalline diamond compact) bits and diamond-impregnated bits. This versatility allows for adaptability to different drilling conditions and formations.
Applicability: The diamond reaming shell finds applications in different geological formations, ranging from soft to hard formations. It is commonly used in oil and gas exploration, geothermal drilling, and other industries requiring precise and efficient borehole creation.
Overall, the diamond reaming shell's utilization of diamond impregnation technology enables effective and reliable drilling operations, enhancing drilling performance, borehole stability, and geological data acquisition.
