摘要
地震反演是储层预测的一项核心技术。传统的叠后反演是在叠加道集的基础上进行的储层参数预测,损失了原始剖面所包含的岩石物理特征,而叠前地震反演则能充分反映地下的岩石物理特性。以叠前反演理论和方法为基础,充分利用已采集处理的叠前地震资料,在银额盆地进行烃类检测。
Seismic inversion is the key technology in reservoir prediction.The traditional post-stack inversion is based on stack gathers for reservoir parameters predictionlosing the petrophysical characteristics on original seismic profile,while pre-stack inversion can fully feflect the petrophysical characteristics underground.This paper is based on the theory and method of the pre-stack inversion,make fully use of the pre-stack seismic data which is collected and processed,carrying out hydrocarbon detection in Yin-e basin.
