3-D seismic-based subsurface imaging

我试图利用三维地震和其他数据来研究沉积岩中的裂缝发育。裂缝影响各种流体的运动，如碳氢化合物、饮用水和负责成岩作用和矿化作用的流体。在低渗透沉积岩中，与微妙构造相关的裂缝群可能是流体流动增强的区域。这些岩石的岩性特征（如孔隙度、层厚）也会影响裂缝的发育。我的研究小组将使用三维地震数据的高级分析：1)识别细微结构，2)预测岩性。结合这两种类型的分析结果，我们应该能够更好地预测裂缝的分布和方向。其他类型的石油工业数据（如生产数据、井眼测井）将用于验证我们的预测。研究成果将在石油工业、水文地质、构造地质等地球科学领域得到应用。先进的计算技术可以适用于科学和工程的其他目的。

I seek to use 3-D seismic and other data to study fracture development in sedimentary rocks.  Fractures affect the movement of various types of fluids, such as hydrocarbons, potable water and fluids responsible for diagenesis and mineralization.  In low-permeability sedimentary rocks, fracture swarms associated with subtle structures can be zones of enhanced fluid flow.  Lithologic characteristics (e.g., porosity, bed thickness) of those rocks also influence fracture development.  My research group will use advanced analyses of 3-D seismic data to: 1) identify subtle structures, and 2) predict lithology.  By combining results from these two types of analyses, we should be in a better position to predict fracture distribution and orientation.  Other types of petroleum-industry data (e.g., production data, borehole logs) will be used to test our predictions.  The results of this research will have application in the petroleum industry, hydrogeology, structural geology and other geoscience fields. The advanced computational techniques can be adapted to other purposes in science and engineering.
