Seismic Exploration Acquisition Quality Quantitative Analysis and Evaluation System

Abstract

A system for quantitative analysis and evaluation of seismic exploration acquisition quality, which includes a digital seismograph, a workstation processor and a data processor; the digital seismograph is used as a signal acquisition terminal of the seismic exploration acquisition quality quantitative analysis and evaluation system to collect seismic waves and convert them into digital signal, the signal output end of the digital seismograph is connected with the signal input end of the workstation processor, the signal output end of the workstation processor is connected with the signal input end of the data processor, and the signal output ends of the workstation processor and the data processor are respectively used as earthquake Quantitative analysis and evaluation system output of exploration acquisition quality, output seismic waveform images and seismic wave data quality parameters. The invention provides scientific and specific digital basis for selection of acquisition production parameters, provides accurate parameter index digital values ​​for analysis and evaluation of acquisition quality, can improve the quality of seismic acquisition data, and improve the efficiency, accuracy and objectivity of the work of acceptance and evaluation of acquisition data.

Description

technical field [0001] The invention relates to an analysis and evaluation system for the quality of data recorded by instruments in the field of seismic exploration, especially in field acquisition, in particular to a quantitative analysis and evaluation system for seismic exploration acquisition quality. [0002] Background technique [0003] In the field of seismic exploration, seismographs are usually used to collect seismic waves to obtain deep geological information. The analysis and evaluation of the quality of the collected data is mainly through manual review of the monitoring records after the collected data is imaged, relying on the personal experience and technical level of the analysts to judge and give qualitative results. analysis and evaluation results. There are relatively large human subjective factors and random factors in qualitative analysis and evaluation. Analysts have different technical experience and understanding of technical specifications, and ...
