多分量地震勘探技术新进展及关键问题探讨
|
摘要
自20世纪90年代中、后期以来,基于地震各向异性理论的多分量地震技术在实用化方面取得了长足进展。多分量地震技术在解决复杂岩性、裂缝油气藏或者煤系地层的储层预测、裂缝检测、流体识别等方面表现出良好的应用效果与发展前景。本文从多分量地震数据的采集、处理与解释反演的角度,总结了近几年来国内多分量地震技术的新进展,并结合实例展示了一些新的处理、解释技术的效果,剖析了各个环节存在的难点以及存在的问题,并对发展方向做出预测。
Since the middle and late of 1990s,the multi-component seismic based on the theories of seismic anisotropy has achieved lots of progress.The multi-component seismic has shown good application result and favorable development foreground in solving problems such as fracture detection,fluid identification and reservoir prediction in complex lithological reservoirs,fractured reservoirs or coal seams strata.In this paper,some advances in multi-component seismic are summarized in terms of multi-component acquisition,processing,interpretation and inversion.With cases studies to illuminate the effects of these new processing and interpretation approaches,some issues in the multi-component seismic are also discussed respectively.At last,the developing direction of multi-component seismic technique is predicted.
