is designed for oil-and-gas well drilling perforation.

Description

Features and Advantages

• formation perforation making without well casing impacting;
• large diameter holes with neat edge;
• high selectivity while perforating of thinly bedded reservoirs;
• effective perforating of thinly bedded reservoirs containing bottom water and oil, water, gas bearing reservoirs separated by a thin unstable shale break;
• it provides making of perforation in the two-casing well construction.

PGSP-2 perforator is the improved version of PGSP perforator. It provides effective perforation:

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

PGSP perforator is to be used in boreholes, cased with the casing with the diameter of 146-177 mm. 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.
