摘要
震源是保证地震勘探数据采集质量的决定性因素之一。在高山、河流等复杂环境,传统震源常受到道路交通、激发条件等限制而难以应用,对实现高精度地震勘探非常不利。无人机遥控震源充分发挥了无人机不受地形限制的特点,能够有效克服复杂环境对传统震源的限制。在河北洋河实验区开展了无人机遥控震源实验,包括不同激发能量的采集实验、与5台可控震源车对比实验和水中的激发采集实验,并在数据频带和信噪比等方面展开对比分析。实验结果表明,无人机遥控震源勘探性能良好,具有对环境的破坏性小、能源消耗少、操作简单的优点,是复杂环境中低成本的优质震源选择。
The seismic source is one of the key factors for the quality of seismic exploration data acquisition.In complex environments like mountains and rivers,traditional seismic sources are difficult to be applied due to the limitation of road traffic and excitation conditions,which has a negative influence on high-precision seismic exploration.The unmanned aerial vehicle(UAV)remote control seismic source fully takes the advantages of the UAV regardless of the terrain,it can effectively overcome the restrictions of the complex environment.The experiments of the UAV remote source was carried out,including the acquisitive experiments of different excitation energy,comparative experiments with five vibroseis and the acquisitive experiments underwater in Yanghe experimental area in Hebei Province,comparing and analyzing the frequency band and signal to noise radio of the data.The results show that the UAV remote control seismic source has good exploration performance.It has the characteristics of low environmental damage,low energy consumption and easy operation.The UAV remote control seismic source is a seismic source choice with low-cost and high-quality in a complex environment.
