The Bashvzryvtechnologii company sells PKO 89-AT punchers of its own production. The original engineering developments of our company ensure maximum safety and ease of use for perforation systems. The main area of use of PKO 89 perforators is drilling and blasting operations in wells in oil fields. Cumulative hull punch systems are used for the secondary opening of rock layers in cavities filled with liquid contents. Suitable for work in 140 and 146 mm casings.
The outer diameter of the products is 89 mm, phasing from 0 to 180o (this parameter, as well as the length of the cases, varies at the request of the customer). If necessary, the drills can be equipped with roller adapters for convenient descent into wells. It is allowed to assemble individual sections of the hammer drill in the workshop.
