Brief introduction of PDC and PDC bit history

Polycrystalline diamond compact (PDC) and PDC drill bits have been introduced to the market for several decades. During this long time PDC cutter and PDC drill bit have experienced many setbacks in their early stages, also experienced great development. Slowly... Read More

What is the difference between steel body and matrix body PDC bit

PDC drill bit is mainly made by PDC cutters and steel, conbining the good impact toughness of steel and wear-resistance of the polycrystalline diamond compact makes the PDC bit has fast footage in the drilling process. Steel body PDC bit has fast... Read More

What is Reverse Circulation Drilling

The Basics of Reverse Circulation Drilling Horizontal directional drilling isn’t something new. People drilled wells more than 8,000 years ago for subsurface water in hot and dry areas, just not with PDC bits and mud motors like we do today. There ... Read More

What Does Cone Bit Mean?

A cone bit is a tool made of tungsten or hardened steel that crush rocks during the drilling process. It is generally made of three rotating conical pieces with hard teeth that break up rock into smaller pieces. It is a commonly used tool in trenchless drilling operation... Read More

What is the meaning of IADC code for the tricone drill bits

IADC code is short for “International Association of Drilling Contractors”. The IADC Code for Tricone Bits defines its bearing design and other design features ( SHIRT TAIL, LEG, SECTION, CUTTER). IADC Codes make it easier for drillers to describe what kind of rock bit t... Read More

WHAT ARE TRICONE BIT ELEMENTS?
