is designed for creating perforation channels in the casing, cement bond and rock perforating.
Features and advantages
- formation perforating without casing impacting;
- large-size perforated holes with a fine working edge;
- perforating during repair operations in multistring well sidewalls for annular space cementing;
- selective formation perforating of interlaced permeable and packed rock layers;
- thin bed drilling-in.
PS-112 drilling perforator may be used within the wells drilled with a 190-215.90 mm bit and cased with 146-168 mm casing pipes. It is to be run with logging unit and logging truck hoist equipped with a three-core logging cable up to 4,200 m long or a seven-core logging cable 5,400 m long.
