COMPLEX FOR FILLING THE SECTIONS OF TOWED SEISMIC Russian patent published in 2018 - IPC G01V1/20 G01V1/38 

FIELD: seismology.

SUBSTANCE: invention relates to the field of seismic exploration by towed seismic strips and is intended for pumping fillers in the seismic section to give the latter a neutral buoyancy. Complex is proposed for filling sections of a towed seismic box that contains a section tensioning means providing the application of mechanical tension forces to the head and tail clutches of the section, and a filling means for the section, provided with a tank connected by a filler main with a pumping device, and comprising a movable frame with rollers mounted thereon. Frame is configured to form a local vertical section anywhere in the section to be filled. Means for tensioning the section preferably comprises a fixed bracket, a dynamometer, a head hitch, a compensator, a tail hook, a movable platform, a guiding profile, a tension winch with a cable. Filled section is located between the compensator and the tail hook. It is also expedient to provide the complex with an electronic check of the section. Mobile frame of the filling means of the section can be provided with head, bypass and tail groups of rollers.

EFFECT: operative detection and elimination of air voids when filling the section, as well as increasing the maximum permissible tension force of the section when performing work to fill it.
