摘要
目的为满足不断增长的对油气的需求，必须提高地震勘探的精度，这就要提高地震勘探的分辨率．方法采用先进的数字信号处理技术处理地震勘探数据，提高地震剖面的分辨率，建立数字信号重构技术和短时傅立叶变换技术联合重构高分辨率地震剖面的计算模型．结果编制了ＨＲＰＳＲ地震剖面高分辨率处理软件包，并利用地震勘探数据进行了测试，提出了一种利用高低分辨率双层外推技术自动搜索相关层位和断层的新方法．结论经ＨＲＰＳＲ软件处理，主频提高５０％～８０％，有效频带展宽了一倍左右．
Aim\ To meet the need of increasing demand for oil, pricision of seismic exploration must be enhanced For solving this problem, the resolution of seismic exploration should be enhanced first Methods A developed hybrid digital processing technique was used to process seismic exploration data and the resolution was enhanced The hybrid digital reconstruction technique short time Fourier transformation technique model for high resolution seismic section is established Results HRPSR seismic section high resolution processing software package was developed and tested with the practical seismic data A new method of using high low resolution extrapolation technique to search for the relative layers and faults automatically was proposed Conclusion After being processed by HRPSR software package, main frequency has raised 50% to 80% and the frequencyband has widened double
