深反射地震资料处理和解释的初步研究
|
摘要
深反射地震资料处理的关键是从干扰背景中提取和增强深层弱有效信号，提高剖面的信噪比和分辨率。深反射地震剖面的解释要着眼于大的地质构造运动和成因，运用地质规律进行综合地质解释。在解释中，通过分析和研究某些相干干扰波的形成和特点，有助于对深反射地震剖面进行可靠的地质推断解释。
The key to the processing of deep reflection seismic data seems to be the cxtraction and enhancement of deep weak effective signal from the disturbing background, thus arising the signal-to-noise ratio and resolution ratio of the profile. The interpretation of the deep reflection seismic profile should be focused on the large geological tectonism and its genesis; geological rsgularity ought to be used to po rform integrated geological interpretation. In interpretation, the analysis and study of the formation and characteristics of some related disturbing wave would contribute to reliable geological inferanch and niterpretation of the deep reflection set seismic profile.
