反射信号振幅的研究已经成为油气勘探中地球物理研究的一个整体部分。然而,一提到振幅异常往往使地球物理学家想到“亮点”或振幅在横向上异常的增加,这种所谓“热点”或亮点技术已在美国墨西哥湾沿岸和世界其它地区工作得很好。它们已成功地用于陆上和海上勘探。对地球物理信息这种特殊方面的研究日益发展,以致“发亮”效应的反面也成为重 Research into the amplitude of reflected signals has become an integral part of geophysical research in oil and gas exploration. However, mentioning that anomalies of amplitude tend to make geophysicists think of anomalous increases in “bright spots” or amplitudes laterally, the so-called “hot spots” or bright spots have worked well along the Gulf Coast of the United States and the rest of the world. They have been successfully used for onshore and offshore exploration. The study of this particular aspect of geophysical information is growing so that the opposite of the “shining” effect becomes
