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. A method of obtaining seismic records using an impulsive sound source within a bore hole comprising the steps of:
adjusting pressures surrounding an impulsive sound source within a bore hole to change the intensity and character of a sound pulse produced by the impulsive source; firing the impulsive sound source at an adjusted pressure surrounding the impulsive sound source; and acquiring seismic records.
