Method and apparatus for producing sound pulses within bore holes |
摘要 |
An impulse sound source for geophysical studies of the earth for oil, gas and other natural resource exploration and more specifically a streamlined design of a hydraulically controlled sound source that may be inserted into oil wells and bore holes for analysis of geological formations deep beneath the earth's surface. |

1. An impulse sound source, comprising:
an umbilical cable extending through a cylindrical housing; a hydraulic fluid reservoir formed within the housing and supplying an hydraulic pump; an electric motor powered from the umbilical cable and controlling the hydraulic pump; a hydraulic cylinder controlled by the hydraulic pump; a reset piston movable within a fluid filled piston chamber using the hydraulic cylinder, the reset piston having a flange movable within an implosion chamber; a free piston having an annular rim and cup within the implosion chamber; an anvil within an impact chamber adjacent the implosion chamber; an elastomeric bladder enclosing a fluid filled sound transmission chamber adjacent the impact chamber; and wherein the free piston is accelerated by hydrostatic pressure within the implosion chamber to strike the anvil and transmit a sound pulse through the sound transmission chamber and the elastomeric bladder. |
