相干体解释断层方法测试及泾河油田的应用

    COHERENCE INTERPRETATION METHOD FOR FAULT: TESTING CASE AND APPLICATION

    • 摘要: 三维地震相干体技术是近年来发展起来的一项新技术,在三维地震解释、特别是断裂解释中应用效果明显。在一些地区和特殊岩性体、特殊类型油藏研究方面取得了良好效果,并且可以较为深入准确地刻画小断层。主要针对鄂尔多斯盆地泾河油田的相干数据体计算做了参数和方法优选,通过对相干层位切片的分析研究,得出了适用于研究区的油藏特征的计算方法和计算参数,达到了准确刻画断层间接预测裂缝发育带的目的。

       

      Abstract: The 3d seismic coherence method is a new technology developed in recent years for 3d seismic interpretation, especially fracture interpretation. The application of the method is rather successful, in particular, to some special type of reservoirs and lithological associations in some areas. It may even disclose small faults. In this article, we take the Ordos Basin as a case to demonstrate the process to optimize the methods for parameter calculation and the coherent data volume calculation. Based on the analysis of coherent slices, the method and parameters, which are suitable for the study area, are concluded and presented in the paper. Using this method, faults can be described accurately, and the fracture zones be predicted indirectly.
