Abstract
Die Erfindung betrifft das Gebiet der seismischen Bodenuntersuchung, insbesondere Untersuchungsverfahren, die Reflexionswellen bei der Untersuchung von steil geneigten Oberflaechen: von Salz, eines Riffs, eines Bruches nutzen. Ziel der Erfindung ist eine Erhoehung der Stoerfestigkeit der seismischen Bodenuntersuchung, der Kartierungsgenauigkeit von steil geneigten Oberflaechen der Trennungsflaeche und der Tiefe der Untersuchung. Es werden Wellen mit zwei Reflexionsvorgaengen - Duplex-Wellen - genutzt. Die Explosions- und Empfangsstelle sind in Richtung Abfallen der steilen Neigung in einer Entfernung angeordnet, die die doppelte Entfernung von der "Stelle der Erregung zur Projektion des Grenzgebietsteils der zu untersuchenden Oberflaeche auf die Kontrollinie" ueberschreitet. Ihre Registrierung und Erregung erfolgt entsprechend einem gemeinsamen Punkt der doppelten Reflexion, der sich auf der steilen Neigung der zu untersuchenden Oberflaeche befindet.The invention relates to the field of soil seismic surveying, in particular to methods of investigation which use reflection waves in the study of steeply inclined surfaces: salt, a reef, a fracture. The object of the invention is an increase in the impact strength of the soil seismic survey, the mapping accuracy of steeply inclined surfaces of the separation area and the depth of the investigation. Waves with two reflections - duplex waves - are used. The explosion and reception points are located in the direction of the steep inclination, at a distance which exceeds twice the distance from the "point of excitation to the projection of the boundary area of the surface to be examined on the control line". Their registration and excitement occurs according to a common point of double reflection, which is located on the steep slope of the surface to be examined.
