Lateral Explusion of Pore Fluids during Vertical Loading of Sedimetary Strata

该项目开展了一项为期两年的研究，研究构造和沉积过程对沉积层垂直加载所产生的孔隙流体的侧向排泄。研究的重点是1)压实和地形驱动的侧向流动作为沉积层中质量和热量传输的一种机制，2)孔隙度和渗透率的时空变化引起的孔隙水流动模式的变化，3)侧向流动的地球化学和古地磁证据及其制约，4)将这些结果应用于阿巴拉契亚前陆盆地、科尔维尔前陆盆地和墨西哥湾北部被动边缘的孔隙流体和烃类的横向运移。该项目的目标是更好地了解沉积层中孔隙流体运移和成岩作用的作用，并能够将这一信息定量地用于评估流体作为沉积盆地中热质传递机制的排泄作用。

The project carries out a two year study of lateral expulsion of pore fluids resulting from vertical loading of sedimentary strata by both tectonic and depositional processes. The study focusses on 1) compaction and topography-driven lateral flow as a mechanism of mass and heat transport in sedimentary layers, 2) variations in the flow pattern of pore water caused by the temporal and spatial changes in porosity and permeability, 3) geochemical and paleomagnetic evidence for and constraints on lateral flow, and 4) application of these results to the lateral migration of pore fluids and hydrocarbons in the Appalachian and Colville Foreland Basins and the Northern Gulf Coast Passive Margin. The objective of the project is to better understand the role of pore fluid migration and diagenesis in sedimentary layers and to be able to use this information quantitatively in the evaluation of fluid expulsion as a mechanism for heat and mass transfer in sedimentary basins.
