Title: Methods and apparatus for exploration from a distance of surfaces
IPC: G01V1/00
Filed: 1970-05-13
Abstract: 1315704 Wave energy exploration devices INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 13 May 1970 [14 May 1969] 23209/70 Heading H4D Discontinuities of or surfaces within a surveyed medium are explored by transmitting substantially single-frequency waves of long duration into the medium; recording during a period of shorter duration and after a delay received waves which have been reflected by the surfaces or diffracted by the discontinuities, the transmitting duration and delay being such that waves are received simultaneously from all the discontinuities or surfaces; determining two numbers, one indicative of the relative phase of the recorded and transmitted waves, the other indicative of the maximum amplitude of the recorded waves; and locating from these numbers the positions of the diffracting discontinuities or of images of either transmission or reception points as mirrored in the surfaces. In the Fig. 8 embodiment, for seismic exploration, a constant frequency sine-wave signal is transmitted by one or more vibrators 1. The length of the transmitted signal is controlled by gate 3 and is at least equal to the maximum two-way travel time through a zone of interest. Reflection signals from one or more detectors 4 are fed to processor H in which narrow band filter 5 extracts desired signals at the transmission frequency and filter 8 extracts noise frequencies. Gate 7 opens briefly to pass an ncycle sample of the desired reflection signal to a delay drum 10 with n read-out heads whose outputs are summed at 11, whereby the n-cycles are superimposed to enhance the signal/noise ratio. The number n (e.g. 10) selected depends on the original signal/noise ratio as determined by a comparator 9, being small for high original signal/noise ratios and having a minimum value of ¢. The maximum amplitude a of the enhanced sample is determined at 12 and magnetically (preferably digitally) recorded at 15, together with the value # of the phase of the sample relative to the transmitted signal as determined by phase comparator 13. By applying the several a and # values resulting from the use of one vibrator 1 and several detectors 4 (or vice versa) to a computer J, the image point of the vibrator (or detector) as reflected in the subsurface strata can be determined and recorded on paper or film, and hence the reflecting strata can be located. The exploration may be repeated with the same or different constant transmission frequencies, the results being composited. A two-dimensional detector-array may be used. It is stated that the invention may use single-frequency ultrasonic waves or radio-waves and may be applied to the exploration of underwater topographic surfaces, walls of wells, or biological organisms.
