specific Embodiment 1

[0092] Embodiment 1 of the present invention specifically introduces a management method for data collected in the field at exploration excitation points. In this example, the area data must be imported first. The import interface is called the area parameter interface, and the interface includes the area name text box, the area datum elevation text box and the area boundary point coordinate table. Users can manually input the area name, area boundary point coordinates and area datum elevation on the area interface through the human-computer interaction interface, or use the file load button on the interface to load the area name, area boundary point by loading an external file of the area and regional datum elevation, and display these data on the regional interface. After the user clicks the area creation function button on the area interface, the parameters on the area interface are written into the area data structure, and it is judged whether the area record already exist...

specific Embodiment 2

[0094] The embodiment of the present invention specifically introduces the data management method of the exploration excitation point observation system. The data management of the exploration excitation point observation system should be realized after the operation of the first embodiment is completed, that is, after the data management of the field data collected by the excitation point has been completed; at this time, the area management node, the block management node, the excitation line management node, and the excitation point already exist in the in the database. The loading of observation system data is realized by the observation system loading interface. First, select the block where the excitation point data is to be loaded; then load the excitation point observation system data file, which is an observation system file in SPS format or an observation system in other formats document. Decode the observation system file, write the observation system data into the...

specific Embodiment 3

[0096]The embodiment of the present invention specifically introduces the management method of the static correction quantity data of the exploration excitation point. The data management of the exploration excitation point observation system should be realized after the operation of the first embodiment is completed, that is, after the data management of the field data collected by the excitation point has been completed; at this time, the area management node, the block management node, the excitation line management node, and the excitation point already exist in the in the database. The acquisition of observation system data is realized by the seismic data static correction algorithm. First, select the block where the static correction data of the excitation point is to be loaded; then select the static correction seismic data data, static correction algorithm, static correction data type, and static correction data version number; Finally, execute the static correction ca...

Abstract

The invention discloses an excitation point data processing method and a device for seismic exploration. The method comprises the following steps: collecting excitation point observation system data and corresponding excitation point information; according to the excitation point information and a pre-established data management model, determining database position information corresponding to the excitation point observation system data, wherein the data management model is pre-established according to excitation point field collection data; and storing excitation point observation system data according to the database position information. The excitation point data are effectively managed, the problems of data dispersion, retrieval disorder, much redundant information and the like are avoided, and the retrieval and access efficiency of the excitation point data is guaranteed.

Description

technical field [0001] The invention relates to the technical field of excitation points for petroleum seismic exploration, in particular to a method and device for processing excitation point data for seismic exploration. Background technique [0002] Seismic exploration is the use of professional instruments to observe the elastic wave properties of rocks for exploration. Seismic exploration uses the law of elastic wave propagation in underground rock strata excited by artificial seismic source to determine underground mineral deposits. In seismic exploration, explosion and hammering sources are generally used to excite seismic waves. The rock near the seismic source is ruptured and plasticized due to the instantaneous huge excitation force, and in the area far enough from the seismic source, the geological medium is only subjected to an instantaneous, small external force. Therefore, the geological medium can be approximately regarded as an ideal complete elastic body. ...
