叠前振幅补偿技术应用与研究
|
摘要
在地震资料的处理和解释中,地震记录的振幅信息是一个非常重要的参数,对改善勘探精度起着非常重要的作用。由于受到地层吸收衰减的影响,地震波在地下介质中传播时会引起高频能量的地震波受到损失以及相位畸变,因此叠前振幅补偿是必不可少的。在地震数据处理中,随着反射法的不断发展,人们需要对振幅信息进行更精确的处理,这为后续的高品质地震偏移成像奠定了基础。
The amplitude information of seismic record is a very important parameter, which plays a very important role in improving the precision of exploration in the processing and interpretation of seismic data. Due to the influence of layer absorption attenuation, seismic wave propagation in the underground medium will cause loss of high-frequency energy seismic wave and phase distortion, so pre-stack amplitude compensation is essential. In seismic data processing, with the continuous development of reflection method, amplitude information needs to be processed more accurately, which lays a foundation for subsequent high-quality seismic migration imaging.
