High-strength seamless steel pipes specifically designed for perforation operations in oil and gas wells are used to carry perforating charges, detonating cords, and carrier frames. These pipes are lowered into the target formation within the wellbore. Upon initiation, they penetrate the casing, cement sheath, and connect with the reservoir's oil and gas, serving as the core carrier material for completion perforation in oil and gas wells.
Steel Grades: GYSKGH120, GYSKGH140, GYSKGH150, GYSKGH165
Constructed with high-quality alloy seamless tubes and subjected to quenching heat treatment, it is resistant to high pressure, explosion, and impact. During detonation, it will not burst, split, or deform.
The microstructure is uniform, with strong resistance to compression and external extrusion, making it suitable for high-temperature, high-pressure, and high-fluid-column pressure environments underground.
According to the perforation pattern plan, holes are precisely positioned and drilled with strict standards on hole spacing, phase, and diameter, resulting in a high success rate for perforation.
It withstands the explosive impact at the moment of detonation, ensuring the gun body remains intact without rupturing, thereby preventing wellbore accidents such as falling into the well or stuck pipe.
The perforation cartridges exhibit orderly arrangement and stable strength, with precise detonation posture, sufficient penetration depth, and uniformly distributed holes, resulting in effective oil and gas flow conductivity. They feature high dimensional precision and excellent adaptability for sub-surface deployment.
Strict control over straightness, ellipticity, and outer diameter tolerance ensures smooth passage of the gun body, allowing it to easily adaptation through corresponding specification casings. The internal diameter remains stable, facilitating seamless assembly of the casing, perforating cartridges, and detonating cords. It is compatible with both factory pre-assembly and on-site assembly modes.
