Wholesale API natural gas tricone rock drill bits with metal face sealed bearing from China factory.
Bit Description:
IADC: 517-TCI journal sealed bearing bit with gauge protection for soft to medium soft formations with low compressive strength.
Compressive Strength:
85-100 MPA
12,000-14,500 PSI
Ground Description:
Medium hard and abrasive rocks such as sandstones with streaks of quartz, hard limestone or chert, hematite ores, hard, well-compacted abrasive rock such as: sandstones with quartz binder, dolomites, quartzite shales, magma and metamorphic coarse grained rocks.
We can offer tricone bits in a variety of sizes (from 3” to 26”) and most of IADC Codes.
As a geophysical logging channel, it can obtain various geophysical data of underground rock and mineral layers.
As an artificial channel, it can observe the underground geological conditions and the underground fluid dynamics.
Using wellbore to exploit underground oil, natural gas, groundwater, geothermal resources.
The technique used in drilling boreholes for oil and gas exploration and development.
It mainly includes well design, selection of drill bit and mud, combination of drilling tools, coordination of drilling parameters, deviation control, mud treatment, coring, accident prevention, and treatment, etc.
The characteristics of oil drilling technology are a deep hole, high pressure, high temperature, and many influencing factors.
According to the geological and geographical conditions and engineering needs of oil and gas exploration and development, there are two types of vertical Wells and directional Wells. The latter can be divided into general directional Wells, horizontal Wells, and cluster Wells.

1. How to get an exact quotation?
Answer: Please send us detailed information as below:
-Tricone bits(Diameter, IADC code)
-PDC bits(Matrix or Steel body, blades quantity, cutter size, etc)
-Hole opener(Diameter, size of pilot hole, hardness of rocks, thread connection of your drill pipe, etc.)
-Roller cutters(Diameter of cones, model number, etc.)
-Core barrel(Diameter, quantity of cutters, connection, etc.)
A simple way is sending us photos.
Besides above, if possible please provide more information as below:
Drilling depth in vertical well drilling, Drilling length in HDD, hardness of rocks, Capacity of drill rigs, application(oil/gas well drilling, or water well drilling, or HDD, or foundation).
Incoterm: FOB or CIF or CFR, by plane or ship, port of destination/discharge.
The more information provided, the more exact quotation will be offered.
