Smooth reaming process-optimized cutting geometry design diamond
reaming shell
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. | Reaming classification | | T series | T36,T46,T56,T66,T76,T86 | | Cable series | AWL,BWL,NWL,HWL,PWL(Front end,rear end) | | WT series | RWT,EWT,AWT,BWT,NWT,HWT(single tube/double tube) | | T2/T series | T256,T266,T276,T286,T2101,T676,T686,T6101,T6116,T6131,T6146,T6H | | WF series | HWF,PWF,SWF,UWF,ZWF | | WG series | EWG,AWG,BWG,NWG,HWG(single tube/double tube | | WM series | EWM,AWM,BWM,NWM | | Others | NMLC,HMLC,LTK48,LTK60,TBW,TNW,ATW,BTW,NTW,AQTK
