随着石油的不断开采,开采难度越来越大,勘探开采成本越来越高,前期工程勘探的要求也越来越高,常规的二维勘探技术已经不能满足工程勘察要求。三维地震勘探技术是综合利用各种学科逐渐发展起来的工程勘察技术,该技术的研发成功的解决了勘探结果不准确,图形不清晰,位置不准确等问题,大大提高了工程勘察质量。本文主要介绍了三维地震勘探技术的原理发展现状以及该技术目前存在的问题,并对未来的发展方向进行了展望,对于我国勘察事业的发展奠定了一定的理论基础。
With the constant exploitation of oil, exploitation is more and more difficult, the cost of exploration and production is getting higher and higher, and the requirements of early exploration are getting higher and higher. Conventional 2D exploration technology can no longer meet the requirements of engineering survey. The 3D seismic exploration technology is an engineering survey technique that has been gradually developed by comprehensive utilization of various disciplines. The research and development of the 3D seismic exploration technology has successfully solved the problems of inaccurate exploration results, unclear graphics and inaccurate location, and greatly improved the quality of engineering survey. This paper mainly introduces the status quo of 3D seismic exploration technology and the existing problems of the technology, and prospects the future development direction, laying a theoretical foundation for the development of China’s exploration.
