数字编码技术在雷达、医学等方面广泛成功应用使得将其引入地震探测中成为可能。本文为将数字编码技术引入地震探测中,进行了岩石物性成像仿真实验。首先讨论了编码超声成像原理,分析了编码技术的规律和特点。其次通过激励Golay码,利用FieldⅡ软件包进行了岩石物性超声成像的仿真,并比较了仿真结果的成像分辨率。结果表明,编码技术是提高超声成像质量的有效方法。结果可用于指导野外编码地震探测。
The extensive and successful application of digital coding technology in radar and medical applications has made it possible to introduce them into seismic exploration. In this paper, digital coding technology into seismic exploration, rock physics imaging simulation experiment. Firstly, the principle of coded ultrasound imaging is discussed and the rules and characteristics of coding technology are analyzed. Secondly, through the excitation Golay code, using the Field Ⅱ software package for the petrophysical ultrasound imaging simulation, and compared the simulation results of the imaging resolution. The results show that coding technology is an effective way to improve the quality of ultrasound imaging. The results can be used to guide field-coded seismic exploration.
