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。
In reservoir development and reservoir engineering, three-dimensional seismic exploration technology is playing an increasingly important role in the discovery of 3D seismic applications in these fields every year. In particular, the three-dimensional seismic or time-dependent seismic technique enables the use of computer The days to monitor oilfield development are not far off. Perhaps this monitoring technology will soon become the standard for the oil industry. Field production monitors can be endless, near real time to the formation pressure, temperature and fluid changes sent to the control center. In the control center, the positive and negative inversion of reservoir simulations, elastic waves, and acoustic waves will tell us the answers to these changes and will be used to control reservoir development through advanced computerized video displays. In this paper, we use the four-dimensional seismic amplitude analysis developed by Lamont-Doherty EarthObservato-ry at Columbia University to analyze the LF of sandstone reservoirs in the Eugene Islands 330/388 block of the Gulf of Mexico. Preliminary results show that in a basin like the Northern Gulf of Mexico, changes in the amplitude of three-dimensional seismic reflections can directly reveal the presence of clastic reservoirs in the Tertiary Basin. Successful drilling of Well A-8ST also proves that the change of amplitude of 4-D seismic can effectively help to find reservoirs. At present, we are using the existing logging data combined with seismic inversion technique to further analyze the amplitude changes. We believe this four-seismics technology, which uses repeated 3D seismic exploration, will play an increasingly important role in reservoir development and production.
