富锦-友谊地区航空电磁测量影响因素分析
|
摘要
航空电磁法作为一种快速有效的地球物理勘探方法,近年来被广泛应用于各个研究领域。为了对影响直升机时间域航空电磁测量的因素进行分析和评价,通过对黑龙江富锦-友谊地区进行航空电磁测量,分析在不同的测量条件下对测量数据的影响,包括不同发射基频以及不同飞行高度。同时对测量数据质量进行评测,通过不同的飞行指标是否满足精度来评测本次飞行的稳定性和可靠性。评价指标包括重复线测量数据质量、飞行高度以及测线偏航统计等。分析结果表明:本次飞行工作所采集的航空电磁数据可靠,通过电导率深度剖面图说明所选取的飞行高度和发射基频合理。本次研究工作为今后更好地开展航空电磁测量提供了依据。
As a fast and effective geophysical exploration method,airborne electromagnetic method has been widely used in various research fields in recent years. In order to analyze and evaluate the factors affecting the airborne electromagnetic measurement in the helicopter time domain,the airborne electromagnetic measurement in the Fujin-Youyi area of Heilongjiang Province was used to analyze the influence of the measurement data under different measurement conditions,including different transmitting fundamental frequencies and different flight heights. At the same time,the measurement data quality was evaluated,and the stability and reliability of the flight were evaluated by whether the different flight indicators meet the accuracy requirements. The evaluation indexes included the data quality of the repeated line measurement,the flight height,and the line offset statistics. The analysis results show that the airborne electromagnetic data collected by this flight work is reliable,and the selected flight height and emission fundamental frequency are reasonable through the conductivity depth profile. This research work provides a basis for better airborne electromagnetic measurement in the future.
