摘要
本文结合东濮凹陷深层地震勘探的实际情况,针对深层地震信号衰减快、频率低和能量弱的特点,对深层三维地震勘探的主要方法和几项关键技术进行了探讨,并对深层地震勘探中应考虑的问题及应采取的措施进行了洋细的分析。在东濮凹陷前梨园地区进行的深层三维地震勘探,所得资料的信噪比和分辨率有了明显的提高。
Combining the real condition of deep seismic exploration in Dongpu depression and aiming at the characters of fast attenuation, low frequency and weak energy of deep seismic signal, the paper discussed main method and some key techniques of deep 3-D seismic exploration and also discussed in detail the problems should be considered and the measures should be taken in deep seismic exploration. By taking these measures,the deep 3-D seismic exploration in Qianli'y'yuan region, Dongpu depression has been carried out, and the signal-to-noise ratio and resolution of seismic data has been greatly improved.
