面向油气勘探开发提升地震偏移及属性刻划水平
Improving the Level of Seismic Wave’s Migration and Attribute’s Description in Face of Exploration and Exploitation
【摘要】 针对复杂地质条件油气勘探开发的需求 ,仅就运用地震资料提取地质属性及构建油储模型所可能面临的难点 ,阐明必需提升地震波传播及成像研究水平的基础理论命题和数值计算的关键环节 .文中着重于用形象的数值图像结果 ,说明开展此类研究的必要性 .对我国而言 ,前新生代海相碳酸盐岩勘探和今后相当时期内对国民经济仍起支撑作用的东部老油田外围及深部油气的勘探开发 ,这两类研究对象尽管其地质演化年代及过程各异 ,但对地球物理偏移成像技术进步及油储建模而言 ,对提升探测的理论所提出的要求 ,都属于近代的难题 .文中还阐明这类研究已是刻不容缓的原因所在
【Abstract】 To meet the need of exploration and exploitation under complex geological condition, some basical theoretic propositions of improving the level of the seismic wave’s propagation and imaging are illustrated in this article. Some key problems in numerical computation are presented also. It is only in according with the difficulties that may be faced in extracting the geological attributes and building the model of reservoir with seismic data. Those results are emphasized on some actual images to describe the necessity of this kind of research. As we known, old oilfields in the east of China are main supports of our national economics. The exploration and exploitation of "Pre cenozoic Marine Carbonate Rock" and these oilfields’ periphery and deep part are two objects of research. In respect of the progress in seismic migration, imaging and reservoir model building, these two are all difficult to promote the theory of exploration in recent years although some differences exist in the age and process of geological evolution. Author also explains why this kind of research is serious.
