Perforating Gun Pipe

Perforation is an extremely important technique in petroleum exploration and recovery engineering, a major means of enhancing the recovery factor of gas and oil wells and also a typical method of tapping the potential of existing oil fields and increasing output. Perforation completion is widely used in China and abroad and accounts for about over 90%of all well completions. Almost all reservoir beds can be opened by this method. In the method  in the course of gas and oil field exploitation the production casing is lowered and cemented  and then special perforation instrument and devices are sent down to the predetermined depth and aimed at the target layer. The perforator down in the well is ignited from ground and the  the lined cavity charge is ignited which result in the detonation wave  to transmit forward at a velocity of 7~8 kmper second and high temperature and high pressure shock waves are generated which penetrate though the casing, cement sheath and enter the stratum forming a hole canal, as illustrated by the diagram. Whichever perforation method you use, the performance and quality of the perforating gun shall have a significant influence on the perforation quality of gas and oil wells.


Classification of product: Oil pipe accessory (mechanical pipe).

Subclassification of product: Perforating gun pipe (or barrel).

Application : Perforation operation in the gas and oil industry.

Technical features: High strength, high ductility.

Standard: ASTM A519 and part of API 5CT requirements.

We has accumulated rich experience and laid a solid technical foundation by taking full advantage of its advanced PQF unit and superior heat treatment line, many years of technical exchange and cooperation with customers and profound understanding of the process technology of gas and oil wells. Up to now SCOTON can provide a series of low alloy seamless pipes as parts of  perforator.
