The Ge Ruite 8 1/2″ GM1316T PDC drill bit has increased its service life by 30% and its mechanical drilling speed by 27% when used in drilling a certain block in the Songliao Basin

The drilling of the deflection section from 2895 to 3498 meters has been completed, with an average mechanical drilling rate of 5.02 meters per hour

Advantages:

Effectively increase the mechanical drilling speed of the drill bit by 27%

The drilling of the entire deflection section has been completed.

48 hours of pure diamond time were saved.

Compared to adjacent wells, the service life of the drill bit is increased by 30%.

Block information:

A certain block in the Songliao Basin.

Total well depth: 4069m

From the K1q to K1yc horizons, the lithology consists of fine sandstone, hard limestone, and mudstone, with gravelly sandstone contained.

Water-based drilling fluid, with a specific gravity of 1.2

Connect the threaded rod and drill in.

Drilling difficulty:

In the build-up to the final drilling section (2895-3498m), the well deviation increased from 1 to 85.6 degrees, and the drilling was completed in one trip.

A high mechanical drilling speed is required, and there is a high demand for stability of the tool face during the directional drilling process.

Great rill Bit Solution:

Using the latest imported composite inserts, optimizing the layout of cutting teeth, and adopting an asymmetric structure for the drill bit wings, as well as optimizing hydraulic parameters, the entire inclined well section was drilled in one pass, with an average mechanical drilling rate of 5.02m/h

The drill bit shows minimal wear after being pulled out of the well and can still be used.

The customer is highly satisfied with the GM1316T PDC drill bit and has vigorously promoted it in this block.
