摘要： The present invention relates to an improved downhole seismic source for the simultaneous generation of elliptically polarized shear wave seismic energy and compression wave seismic energy coupled into a borehole. The source of the present invention is capable of receiving several kilowatts of energy downhole to depths of several thousand feet. An orbital vibrator, energized by a hydraulic power means is disposed within a housing. The orbital vibrator imparts an orbital motion which generates seismic wave energy in the borehole. A cable supports the hydraulic power means and the orbital vibrator at selected positions along the borehole for coupling of the seismic wave energy into the borehole.

摘要： The present invention relates to an improved downhole seismic source with an epicyclic eccentric weight system for the simultaneous generation of elliptically polarized shear wave seismic energy and compression wave seismic energy coupled into a borehole. The apparatus includes a cylindrical housing and a drive means or electric motor disposed in the housing which provides rotational output to an epicyclic eccentric weight system also disposed in the housing. Expandable tapered wedging collars are used to firmly secure the motor and the epicyclic eccentric weight systems within the housing. A flexible shaft interconnects the centerline of the epicyclic cylindrical roller and the motor whereby the roller receives the rotational output from the motor. The shaft rotates in one direction and the roller rotates in the opposite direction thereby producing an epicyclic motion.

摘要： A film supply roll adapter includes a main support through which a rod having a flange on one end for receiving a film roll and another end attached to a cylindrical connector, an open section on the cylindrical connector is adapted to fit on a film roll holder in a laser plotter. The rod is configured within the main support to permit free axial rotation in order to transmit the drag force of the film roll holder directly to the flange with essentially no increase or decrease. The main support is arranged and may be fitted with O-rings to nest within a film roll housing and block all light from being incident on the film.
