基于地震影像学原理的地震属性技术及应用
|
摘要
随着勘探程度的不断加深及勘探开发对象复杂程度的增加,隐蔽性油气藏逐渐成为未来油气勘探的重点,这使得地震资料解释技术从单纯的构造解释向更精确的储层预测、油藏描述等方向发展,而地震属性分析技术在其中发挥了越来越重要的作用,已经成为油藏地球物理研究的核心内容。本文基于地震影像学原理,利用三维岩相解释技术对研究区提取了相关地震属性,并在此基础上利用RGB—IHS多谱成像原理进行多属性的融合。研究结果表明,多属性融合技术降低了地质体的不确定性,对于该区的勘探和开发具有一定的指导意义。
As the exploration depens, with the increasing complexity of the exploration and development object, the subtle reservoirs have gradually become to be the focus of future oil and gas exploration, which makes the seismic data interpretation techniques shift to more precise reservoir prediction and description from the simple structure interpretation, the seismic attribute analysis technology has played a more and more important role in it, and has become the core of the reservoir geophysical research. In this paper, based on the principle of seismic imaging, relative seismic attributes were extracted by using three-dimensional litho facies interpretation techniques, and on this basis the RGB-IHS multi-spectral imaging principle were used to multi-attribute fusion. The findings show that the multi-attribute fusion technology can reduce the uncertainty of the geological body and also can provide guidance for the exploration and development in the area.
