The perforating gun barrel (also known as perforating gun tube or petroleum perforating barrel) is a high-strength seamless steel pipe specifically designed for perforation operations in oil and gas wells. It carries perforating charges, detonator cords, and charge carriers, is lowered into the target formation, and upon detonation penetrates casing and cement annulus to connect reservoir fluid with the surface, serving as the core carrier material for well completion perforation.
Steel grades: GYSKGH120, GYSKGH140, GYSKGH150, GYSKGH165
The perforating gun barrel is a high-strength specialized steel pipe designed for installing perforating charges downhole. It withstands extreme temperatures and pressures, remains resistant to explosions without deformation, ensures safe perforation operations, and precisely penetrates oil formations—making it an essential component in oilfield completion systems.
Manufactured from high-quality alloy seamless tubes subjected to quenching and tempering heat treatment, these pipes exhibit exceptional resistance to high pressure, explosion, and impact; they do not crack, split, or deform during detonation.
The metal exhibits a uniform microstructure, superior compressive and extrusion resistance, making it suitable for underground environments characterized by high temperatures, high pressure, and elevated fluid column pressures.
The perforations are precisely positioned according to the designated pattern, with strict adherence to standard specifications for hole spacing, phase alignment, and diameter, resulting in high perforation success rates.
Resistant to corrosion from formation brine and sulfides, suitable for long-term operation in conventional wells, heavy oil thermal recovery wells, and sulfur-containing oil and gas wells.
It features specialized precision threaded connections at both ends, ensuring excellent sealing and robust connectivity. The multi-section barrel can be quickly assembled in series for convenient on-site installation.
Compatible with various well diameters: common specifications including 89,102,114,127, and 140 mm, suitable for perforating vertical, inclined, and horizontal wells.
It withstands the explosive impact force instantly during detonation, remains intact without cracking, and prevents underground accidents such as falling into wells or getting stuck.
The boreholes are well-defined with stable strength; the perforating charges exhibit precise detonation alignment, sufficient penetration depth, uniform hole distribution, and excellent oil and gas flow guidance performance.
It is suitable for complex operating conditions such as deep wells, high-temperature wells, high-pressure wells, heavy oil thermal recovery wells, and sulfur-containing wells.
With standardized structures and threads, it is compatible with various perforation tools, cartridge holders, and couplings, enabling rapid installation and removal of tubing strings on-site with high operational efficiency.
