Abstract

The present invention provides a seismic data processing method and device for calculating the rotation component by using the translational component. The method includes: obtaining the translational component collected by multiple seismic stations and the position information of each seismic station; Including the first seismic station and multiple second seismic stations set around the first seismic station; the translational components collected by multiple seismic stations come from the same source; according to the obtained translational component and position information, determine the seismic source Theoretical value of the rotational component propagating to the first seismic station. Through the technical solution of the embodiment of the present invention, it is possible to make comprehensive use of the translational components collected by the dense station array including the first seismic station and a plurality of second seismic stations arranged around the first seismic station. The rotation component is obtained by calculating the rotation component and the position information of each seismic station, thereby improving the accuracy of the converted rotation component.

Description

technical field [0001] This document relates to the technical field of seismic observation, in particular to a seismic data processing method and device for calculating the rotational component by using the translational component. Background technique [0002] The motion of the earth's medium caused by earthquakes includes translational and rotational components. The distribution of subsurface seismic wavelengths can be fully described by combining translational and rotational components. With the development of modern sensing technology, seismographs capable of measuring the rotational component have emerged. However, the production technology of the rotational component seismograph is high and expensive, which greatly increases the acquisition cost of the rotational component. Therefore, the number of rotation component seismometers is relatively small, and the data of the rotation component measured by the rotation component seismometers is very little. [0003] In th...
