FIELD: technology for registering wave processes in wells.
SUBSTANCE: as a pressing means for the device, controlled electro-mechanical pressing device is used. One group of pressing levers jointly connects rod of pressing means and containers with seismic receivers. Another group of pressing levers connects body of pressing device to containers. This provides for pressing of lower portion of receiver with same force as in the upper. Lengths of levers in each group are equal and length of each pressing lever should exceed minimal distance between points of connection of these to container and pressing device.
EFFECT: higher precision of measuring of wave parameters during their registration in the well.
