The 537 roller bit performs excellently in drilling quartz sandstone formations

The footage is 162 meters, with an average mechanical drilling speed of 3.11 meters per hour

The drilling of the deflection section in the quartz sandstone formation has been completed, covering the well section from 2241m to 2378m. The well deviation ranges from 28 to 45.8 degrees, with an average mechanical drilling rate of 3.11m/h. In conjunction with the directional screw for large-section sliding drilling, this section saved 22 hours of pure drilling time compared to the adjacent well. After the drill bit was pulled out of the well, there was no tooth loss or chipping, with only normal wear on the back of the palm.

Advantages of drill bits:

The special tooth arrangement and bearing structure ensure efficient and safe drilling of the drill bit.

The drilling time for this section has been effectively reduced.

The specially designed stabilizing block enables the drill bit to maintain a stable tool face during the directional drilling process.

The gage strengthening treatment effectively improves the gage maintaining capability of the drill bit during the directional drilling process.

Block background:

A certain block in the Songliao Basin.

For large-section sliding drilling, it is necessary to effectively ensure the mechanical drilling rate during the directional deflection process.

High-hardness and strongly abrasive formations have high requirements for drill bits

Performance of Geruite drill bits:

Complete the drilling operation of the deflection section in one trip.

Compared to the operation of making a deviation near the well, it was completed one day earlier.

After the drill bit is pulled out of the well, there are no phenomena such as chipping or tooth loss
