地震岩石物理研究进展

Review of progresses in seismic rock physics

地震岩石物理(Seismic Rock Physics)是研究岩石物理性质与地震响应之间关系的一门学科,旨在通过研究不同温度压力条件下岩性、孔隙度、孔隙流体等对岩石弹性性质的影响,分析地震波传播规律,建立各岩性参数、物性参数与地震速度、密度等弹性参数之间的关系,本文主要论述了半个多世纪以来,国内外地震岩石物理在岩石、流体基础研究、烃类检测等方面取得的主要进展,并分析目前国内岩石物理的研究现状、存在的问题、最新研究动向及展望。

Seismic rock physics carefully and purposefully uses rock physics data and theory in the interpretation of seismic observations. Its purposes are to show the impacts of porosity, fluids in pores and lithology on the rock elasticity under the situ pressures and temperatures, to help to characterize the seismic wave propagation, and to establish the relationship between the lithology, property parameters, seismic wave velocity, density and some other elastic parameters. This paper will discuss the main progresses of seismic rock physics in theory, empirical relationship, models and the applications in the fields of seismic exploration and reservoir characterization. And the paper will also discuss the difficulties faced in seismic exploration, some application conditions and limitations of rock physics theory, the latest study trend and prospects of seismic rock physics.
