| 摘要: |
| 笔者在前人研究的基础上,对地震沉积学的理论、研究现状和发展趋势进行了较为全面的阐述,并对地震沉积学的关键技术问题进行了较深入的讨论。地层切片是应用沿两个等时界面间等比例内插出的一系列层面进行沉积体系和沉积相平面展布研究的技术;90°相位转换(调整)使地震相位具有了岩性地层意义,可以用于高频层序地层的解释;基于不同频率地震资料反映的地质信息的不同,采用分频段解释的方法,可使地震结果的解释更加明确。由于受地震分辨率和解释手段的限制,地震沉积学的研究目前还存在诸多问题,但是作为一门新兴学科,它已成为隐蔽油气藏勘探的一个突破口。 |

| Abstract: |
| The present paper gives a general view of theory,current state,future development and key techniques of seismic sedimentology.The technique of stratal slicing is proposed to be applied to the study of the planar distribution of sedimentary systems and sedimentary facies.The technique of 90° phasing may provide the high-frequency sequence stratigraphic interpretation.As a rising discipline,the seismic sedimentology will make a breakthrough in the exploration of subtle hydrocarbon reservoirs. |
| Key words: seismic sedimentology stratal slicing frequency decomposing 90° phasing of seismic data |
