| 摘 要： | 在油藏开发和油藏工程方面，三维地震勘探技术正在起着越来越重要的作用，每年都可发现三维地震在这些方面的应用，特别是时间延续的三维地震即四维地震技术使得用计算机来监测油田开发的日子已为期不远。也许这种监测技术不久将成为石油工业的标准。野外生产监测仪可以源源不断、近真时地把地层压力、温度和流体的变化送到控制中心。在控制中心，油藏模拟、弹性波和声波的正反演将告诉我们有关这些变化的答案，进而通过先进的计算机视像显示来控制油藏的开发。文中我们应用在哥伦比亚大学Ｌａｍｏｎｔ－ＤｏｈｅｒｔｙＥａｒｔｈＯｂｓｅｒｖａｔｏ－ｒｙ发展的四维地震振幅分析技术分析了墨西哥湾ＥｕｇｅｎｅＩｓｌａｎｄ３３０／３３８块中的沙岩油气藏ＬＦ。初步结果显示，在类似北墨西哥湾的盆地中，连续三维地震反射振幅的变化可以直接显示第三系盆地中的碎屑岩油气藏的存在。井Ａ－８ＳＴ的成功钻探也证明了四维地震振幅的变化可以有效地帮助寻找油气藏。目前，我们正利用现有的测井资料结合地震正反演技术进一步分析振幅的变化。我们相信这种应用重复三维地震勘探的四雏地震技术将在油藏开发和生产中起着越来越大的作用。

| Abstract: | Dseismic technologies have progressed to the point that new reservoirproduction and engineering applications are being discovered yearly.In particular,4-D,ortime-lapse,seismic monitoring offers the possibility that computer control of field develop-ment may someday be the industry norm. We see a future in which continual refinementsto the 4-D seismic solution are strongly coupled to forward and inverse models of differentattributes(reservoir ,elastic,and acoustic),all of which are used to understand changesobserved in pressures,temperatures,and fluid contents coming into control centers fromthe monitoring of all wells in a field── in near real-time. These diverse datasets will be e-valuated by teams of production engineers,geologists and geophysicists, They,in turn,will control reservoir production through a “visualization nexus”that allows this interac-tion to occur.Thecase study of LF reservoir in Eugene Island Block 330/338,offshore Louisiana, Gulf of Mexico,presented in this paper is implemented by using the 4-D seismic amplitudetechnique developed at Lamont.The preliminary result shows that reflection seismic am-plitude differences of repeated 3-D seismic surveys can be used as a direct hydrocarbon in-dicator in Tertiary basins,particularly ’the basins like the Northern Gulf of Mexico basin.The success of A- 8ST well strongly support the optimal location of bypassed hydrocarbonpredicted by amplitude differences. Currently,the 4-D seismic amplitude differences arefurther investigated to calibrate with the available wireline logging data through the seis-mic forward and inverse models. The application of 4-D seismic technologies that use re-peated 3-D seismic surveys will gradually play dominant roles in reservoir development andexploration. |
