地震地层学的任务是利用反射地震资料研究地质历史、沉积环境、岩性岩相分布,从而指导找油(特别是寻找地层油藏)工作.其内容包括:1)地震波在地层中传播的物理基础;2)地震剖面的地质解释;3)地质地震模拟.地震地层学是数字地震技术与现代沉积学概念相结合的产物,其目的在于利用沉积学的概念解释数字地震剖面中蕴藏着的大量地质信息.构成反射的物理基础和解释地震剖面时的条件限制影响地震波在地层中传播并形成反射的因素很多,从地质上讲有岩性、流体成分及
The task of seismic stratigraphy is to study the geological history, sedimentary environment and distribution of lithology and lithology by using reflected seismic data to guide the search for oil, especially for stratigraphic reservoirs, and its contents include: 1) The physics of seismic waves spreading in strata 2) Geological interpretation of seismic profiles 3) Geological seismic modeling Seismic stratigraphy is a product of a combination of digital seismic techniques and modern concepts of sedimentology, with the aim of using the concept of sedimentology to explain the vastness of the digital seismic profiles Geological Information Constraints in Physical Constitutes of Reflections and Interpretation of Seismic Profiles There are many factors that influence the propagation and reflection of seismic waves in the formation. Geologically speaking, lithology, fluid composition and
