Oriented Perforating Guns and Accessories Series
Oriented and angle-specific perforating guns are currently available in Model 102 and Model 127 versions; other models can be designed to meet specific user requirements.
These guns are suitable for perforating thin oil and gas reservoirs where the formation dip angle relative to the surface ranges from 20° to 60°.
They achieve oriented perforation through the use of an eccentric-weighted gun body combined with a swivel joint or an orienting linkage mechanism.
They are suitable for wellbore perforation operations where the casing inner diameter is at least 20 mm larger than the gun body’s outer diameter.

Conventional Perforating Gun and Accessory Series
There are ten standard models of perforating guns: 51, 60, 68, 73, 89, 102, 114, 127, 140, and 178.
In recent years, the company has developed the Model 102 thin-walled gun (with a wall thickness of 7 mm) and an ultra-thin-walled gun for low-pressure wells (with a wall thickness of 5 mm).
These perforating guns are suitable for operations in wellbores where the inner diameter of the tubing exceeds the outer diameter of the gun body by at least 15 mm.
The phase angle and shot density for each model can be customized according to user requirements.
