RECORDING METHOD AND DEVICE OF SEISMIC DATA Russian patent published in 2011 - IPC G01V1/16 

FIELD: mining.

SUBSTANCE: these inventions provide such effect as independent operation without using any additional cable routing both from surface and in data acquisition assembly itself, as well as possibility of reliable engagement of the device with the ocean bottom. In general case the proposed bottom seismic data acquisition system includes the following: waterproof housing having the wall representing inner compartment; at least one geophone arranged inside the above housing; clock pulse generator arranged inside the above housing; electric power supply source arranged inside the above housing; seismic data recorder arranged inside the above housing; at that, the above housing with geophone, clock pulse generator, power source and seismic data recorder, which are arranged in it, in general has negative buoyancy; in which the above electric power supply source provides electric power to the whole system developed under water. At that, the above system is independent and all the electronic equipment for the system is arranged inside housing, thus forming fully independent system; at that, the above system also includes external connector supporting electric connection at least to one of the above geophone, clock pulse generator, electric power supply source and seismic recorder; at that, the above connector passes through the wall of the above housing.

EFFECT: above said bottom systems differ from each other by means of number of peculiar design features, for example availability of shock absorber arranged around the housing wall, or availability of cyclic storage device, or availability of latching mechanism arranged on the housing.
