Abstract
1,087,504. Marine seismic prospecting. CONTINENTAL OIL CO. Feb. 11, 1966 [May 20, 1965], No. 6209/66. Heading H4D. A seismic energy generator for marine prospecting includes a housing (36, Figs. 1 and 3) which, during operation, is immersed in the water, the housing containing a piston (42) connected to an hydraulically reciprocated piston-rod (40), the upper surface of the piston being maintained under air pressure substantially equal to that of the surrounding water and supplied via a hose pipe (18). The piston is sealed by means of upper and lower rubber diaphragms (44), (46) which, in conjunction with a sealing ring (92) on the piston edge, form respective chambers (86), (88) into which lubricating oil is introduced via ports (94). The hydraulic motor (116) which is of known type, is actuated by an hydraulic pressure line (20) and exhaust line (22), the connections of which to the ports (172), (176) are alternated by means of a servo valve (28) controlled over a cable (26), the usual operation comprising either an upsweep or a downsweep in frequency in the range 10 to 150 c.p.s. An electromagnetic device (34) operated by the piston-rod supplies signals over cable (24) indicative of the velocity of the rod and these signals are utilized to continually correct the positioning of servo valve (28).
