is designed for turning of drill perforators round the vertical axis for a fixed angle within the range of formation drilling.

Description

Features and Advantages

• alternating hydrodynamic formation load;
• remote pressure reading during hydrodynamic perturbation and perturbation process control;
• hydrodynamic damping process time – 1.5-2 min;
• downhole fluid sampling and transportation to the surface after the perturbation process is finished;
• capability of downhole tool packaging with two tanks.
