摘要： A method for seismic exploration using nonlinear conversions between electromagnetic and seismic energy, with particular attention to the electromagnetic source waveform used. According to the invention, seismic returns from a source waveform are correlated with a reference waveform, with both waveforms custom designed to minimize both correlation side lobes and interference from linear electroseismic effects. A waveform element is selected which may be sequenced by a binary or similar digital code embodying the desired custom design to generate an input sweep with the needed depth penetration and noise suppression. Correlation of the seismic response with the reference waveform in a data processing step mathematically aggregates the seismic response from the input sweep into a single wavelet. Preferred binary digital codes include prescribed variations of maximal length shift-register sequences. Also, an apparatus for generating the desired waveforms.

摘要： Method and apparatus are provided for a new type of geophysical prospecting. The method applies an electric field (111) to a fluid-containing porous subsurface formation (118) to create a fluid pulse from changes in the polarization of pore fluid dipoles. The fluid pulse propagates in the subsurface as a seismic wave (124) that may be detected by an appropriate array of seismic detectors (126). The apparatus is a pulsed DC or AC source (116, 110) for generating an applied electric field (111) and a seismic detector (126).

摘要： L'invention concerne la reconnaissance par sondage électrique d'un sol (20) recouvert d'une masse d'eau (10). On réalise des mesures de résistivité apparente du milieu à l'aide d'un système de paires d'électrodes alignées (AB, M₁N₁, M₂N₂,...) d'écartements différents que l'on dispose sur le sol au fond de l'eau, par injection d'un courant électrique (I) déterminé dans la paire d'électrodes centrale (AB), lequel fait apparaître une différence de potentiel (V) dans l'une des autres paires d'électrodes (M₂N₂) que l'on mesure et d'où l'on déduit une valeur de résistivité apparente du milieu soumis au sondage électrique. Entre le système d'électrodes et la masse d'eau est interposée une feuille électriquement isolante continue (40), dimensionnée de façon à recouvrir largement la totalité du système d'électrodes. Cette feuille constitue une barrière empêchant le courant injecté de circuler dans l'eau.

摘要： The apparent electrical resistivities of various parts of a marine bottom are determined by supplying an alternating electrical current to a pair of current supply electrodes and measuring potential differences between pairs of measuring locations. The locations are on a straight line on the marine bottom. There is a fixed ratio between the distance between the locations of each pair and the distance between said pair and the pair of current supply locations. Adjoining pairs of measuring locations have a measuring location in common. A flexible cable for taking these measurements is described. The determined resistivities are subsequently compared with calculated resistivities to determine the compositions and thicknesses of the soil layers of the marine bottom.

The flow meter comprises an elongated body having a cross section which is substantially smaller than the diameter of the hole; separating members placed at a distance from each other in the longitudinal direction of the body for separating the examined section from the other parts of the hole in a substantially pressure-tight manner; dividing members for dividing the examined section into two sectors in the longitudinal direction of the hole; and a flow channel extending through the body and equipped with a flow sensor for measuring the direction and rate of the flow between the sectors. In accordance with the invention, the dividing members are formed of thin and elastic sealing strips, which have been fixed to the body and, being substantially perpendicular to the surface of the body, arranged to surround and delimit the sectors.
