摘要： The invention relates to a device for seismic emission in an underground formation, comprising one or more vibrators of any type, and to a method of implementing same. In a preferred embodiment, each vibrator comprises at least one pillar (1) of sensitive elements (e.g. piezoelectric type) which is disposed between two end plates or horns (2, 3) and a signal generator which applies vibratory signals at the pillar. Said pillar (1) is encased in a protective sleeve (4) and the vibrator is positioned in a pit or cavity (W) and embedded in a mass of solid coupling material (7) which is in contact with the protective sleeve (4) and with the two end plates (2, 3) on at least one part of each of the respective faces thereof and which connects the vibrator to the surrounding formation. Several of such vibrators can be buried at intervals from one another in the pit. By triggering the aforementioned vibrators in sequence with the desired delays, it is possible to intensify the waves emitted by the device in a preferred direction. The invention is suitable, for example, repeated seismic monitoring of an underground deposit being mined.

摘要： A seismic coupling device for geophones firmly couples seismic sensors to the sea floor. The structure is open for the free flow of sea water and mud through the structure so that it moves freely through the sea water and solidly embeds itself in the ocean bottom. It is preferably made of a corrosion resistant metal, such as stainless steel, which also resists bending forces on the cable take-up reel, and provides further mechanical protection for sensor components enclosed within. A segmented ring at each end clamps around the protective enclosure which encloses the sensor package, and a further pair of segmented rings inside the ends clamps around the enclosure. A plurality of axially oriented longitudinal bars couple to the rings to form a squirrel cage around the enclosure.

摘要： This invention is a method of separating induced microseismicity signals from seismic signals acquired within active seismic monitoring operations carried out in underground zones under development which has application for monitoring of underground hydrocarbon or fluid storage reservoirs. Seismic records are formed from signals emitted by one or more seismic sources controlled by orthogonal signals. In this case, the signals are processed to separate the respective contributions of the at least one seismic source to the signals received and to reconstruct the seismograms equivalent to those that would be obtained by actuating the at least one seismic source separately. The induced microseismicity signals (passive seismic signals) are separated from the seismic signals coming from sources (active seismic signals) essentially by isolating the contribution thereof by comparison with a spectral reference model at the fundamental frequencies emitted and at the respective harmonics thereof, and by reconstructing in the time domain the induced microseismicity signals and the signals coming from the at least one seismic source.
