Snake BVT perforation systems are a product of Bashvzryvtechnologii’s own development. The multi-section design increases the efficiency and manufacturability of drilling and blasting operations in wells of oil and gas condensate fields.
* — phasing of 0, 45, 90, 180 is possible according to Customer’s requirement;
** — other density is possible according to Customer’s requirement
*** — execution of VD by special order
**** — other body lengths are available on Customer’s request
Appointment:
The SNAKE BVT perforation systems increase the manufacturability of blasting operations, and remove the restriction on the maximum intensity of the curvature set.
The uniqueness of such punch systems lies in the presence of detachable joint assemblies, which consist of detonation receiving and transmitting devices. The nodes remain intact after the shaped charges are triggered, which allows the use of chains of perforation systems up to 500 m long. This significantly increases the efficiency and expands the scope of the products.
