    摘要: A method, having application to petroleum exploration or production, for picking the arrival time of seismic waves and use thereof for orienting the components of a multi-component sensor. After acquisition of seismic data using a VSP type method, with a multi-component sensor, a module signal is constructed by calculating the square root of the sum of the squares of at least two orthogonal seismic components. Arrival times of a direct seismic wave are then picked on an amplitude extremum of this module signal. Based on this picking, the seismic components can then be oriented in a unique reference frame whatever the depth of the sensor. A time window is defined on either side of the picked arrival times and the azimuthal direction is determined by maximizing the energy of the horizontal components within this time window. Finally, the three components are oriented in a reference frame defined with respect to the azimuthal direction, which is identical for each depth.

    摘要: The device enables strains of at least one surface (1) of a sample (2) to be measured versus temperature. Strains in a direction perpendicular to a predetermined plane, for example the plane of the surface (1), are measured by composite images. Strains in said plane are measured by image correlation. The measurements by image correlation and by composite images use a common visible light detection camera (3). The sample (2) is arranged in an enclosure (6) transparent at least locally to visible light (L). At least one infrared emitter (9) enables an infrared light to be created in a spectral band for a large part not detected by the camera (3).

    摘要: Apparatus and method for detecting, by means of eddy currents, faults in a metal plate with at least one bore, comprising a differential probe constituted by two coils connected electrically to an apparatus for producing and processing signals and an apparatus for moving the probe in the bore in translation and in rotation. The probe is constituted by a probe body in which a movable element is mounted, supporting the two coils and capable of moving under the action of centrifugal force so as to be applied to the inner wall of a tube inserted in the bore. The invention particularly applies to the testing of a steam generator tube sheet.
