is designed to perforate oil and gas boreholes.

Description

Features and Advantages

• formation penetration without impacting well racker;
• large perforation hole with the sharp edge;
• highly-preferential penetration of thinly bedded formation;
• effective thin bed penetration with bottom water and oil, gas bearing strata with thin instable breaks.

The PGSP-3 tool provides an enhanced penetration with perforation of:

• carbonate reservoir of flow bad properties;
• formation with deep zones of near-wellbore colmated area;
• eccentric casing zones, cavernous boreholes, directional boreholes, keyseating borehole zones.

PGSP-3 drilling perforator can be used in wells, casing string 140-168 mm diameter. It is to be run with log-processing laboratory and logging hoist equipped with 3-core cable up to 4200 m long and 7-core cable up to 5400 m long.
