SYSTEM AND METHOD FOR PRODUCING HIGH QUALITY SEISMIC RECORDS WITHIN BORE HOLES

摘要

A 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 impulsive sound source that may be inserted into oil wells and bore holes and a system and method for obtaining high quality seismic records from the impulsive sound source by adjusting and maintaining pressures within the well or bore hole.

主权项

1. An impulsive sound source for obtaining seismic records within a bore hole, comprising:
a hydraulic pump; a reset piston; a free piston; a movable anvil; and wherein the free piston is accelerated by hydrostatic pressure to strike the movable anvil and transmit a sound pulse through a bore hole to obtain seismic records.
