摘要
针对海陆两栖地区地震勘探激发、接收中存在的问题,通过改造炸药震源的装药结构和起爆方式,研制出了一种新型激发震源,提高了激发信号的品质,减小了与气枪震源之间的信号差异;在接收技术上,研制了新型压电检波器以代替常规的沼泽机电检波器,提高了接收地震信号的频率,实现了水陆相同感应机理的检波器同时接收地震信号,消除了两种不同检波器造成的信号差异;通过对两种新技术的试验分析,认为明显提高了地震资料的分辨率和信噪比,促进了海陆两栖地区地震勘探技术的发展.
For the explored and receives problem that seismic exploration exists in the amphibious area. One kind of new type source has developed. It has raised the character of signal and has reduced the signal difference between source in the amphibious area. on receiving the technology. we have developed a new piezoelectricity detector. It has improved the frequency of receipt seismic signal. It has been realized that the seismic signal is received at the same time with identical response mechanism in the amphibious area, and has eliminated two kinds of signal difference that the different detectors created. It is clearly to have raised the resolution and signal\|to\|noise ratio of seismic datum by the test data analyses of two kinds new technology, and has promoted the development of seismic exploration technology in amphibious area.
