Seismic source and method of generating a seismic wave in a formation

摘要

A Seismic source comprising an actuator having a rotary part ( 104 ) and a reciprocative part ( 105 ), conversion means ( 109 ) in the form of corrugated surfaces to convert a rotation of the rotary part ( 104 ) into a reciprocal movement of the reciprocative part ( 105 ), and a vibrator body ( 106 ) that is connected to the reciprocative part ( 105 ) of the actuator by means of a spring ( 107 ).
