Product Description
Wholesale API oil tricone rock drill bits with metal face sealed bearing from China factory.
Bit Description:
IADC: 417-TCI journal sealed bearing bit with gauge protection for soft formations with low compressive strength and high drillability.
Compressive Strength:
65-85 MPA
9,000-12,000 PSI
Ground Description:
Long intervals of very soft poorly compacted shales, dolomites, sandstones, clays, salts and limestones.
We can offer TCI bits and steel teeth bits in a variety of sizes (
from 3” to 26”) and
most of IADC Codes.
The world's major natural gas extraction countries are the United States, Russia, Turkmenistan, Iran, Qatar, Algeria, the Netherlands and so on. China has also started producing shale gas in recent years. One of the main use of the most do is the metal sealed bearing tricone bits.
Natural gas, like oil, is buried in closed geological formations, some in the same layer as oil, some in isolation.
Natural gas stored in the same zone as crude oil will be extracted along with it.
Due to the complicated geological conditions of natural gas deep well drilling, the unforeseeable engineering geological problems lead to the difference between actual drilling and design and lead drilling to serious drilling complications and accidents, which not only endanger safety and the realization of geological objectives, but also seriously restrict the improvement of drilling speed and significantly increase drilling costs.
