Eccentric Water Well Drill Bits For Down Hole Drilling Rod Of Friction Welding

Eccentric drilling bit for down hole drilling rid of friction welding,drilling bits

1. Product description:

The eccentric bit is a bit whose center of the bit deviates from the axis line due to the asymmetrical distribution of steel body or tire body around the axis line of the bit.

When the bit turns, a lateral force (centrifugal force) is created to cut the hole wall, making the aperture larger.

The eccentric bit is used for the expansion of depth or easy shrinkage hole section under extended casing.

2. Drilling formation principle and factors for eccentric bit

During the follow-up drilling of complex formations, the selected drilling parameters should be based on the principles of low speed, low feed pressure, and high return air speed.

During the construction operation, the hardness and looseness of the rock in the drilled formation should be selected. Factors such as water content and water content control the drilling s peed.
