It is intended to provide a safe replacement rod pumps, during the well works. There is several reasons to use valve cutter with rod pump operation:
- Temporary stoppage of wells when replacing the sucker rod pump;
- Preservation of reservoir properties;
- Work on development wells after underground repairs associated with the replacement pump. Valve is installed in the tubing pipes. Opening and closing the valve is due to the interaction, through an extension cord with a plug-in pump. If necessary, it is possible to kill the well by connecting the pump unit to the valve tubing pipes.
