9804838ScholzSediments deposited in basins undergo physical and chemical changes-diagenesis-and gradually evolve into sedimentary rocks. This project is an experimental study that simulates diagenesis in the laboratory with the goal of understanding the various physico-chemical processes involved. The emphasis is on studying the evolution of porosity and permeability during diagenesis in order to understand the formation of seals in sedimentary basins. Such seals are widespread and they play important roles in the migration and entrapment of oil and gas.

9804838肖尔茨盆地中沉积的沉积物经过物理和化学变化--成岩作用--逐渐演化成沉积岩。 该项目是一项实验研究，在实验室中模拟成岩作用，目的是了解所涉及的各种物理化学过程。 重点是研究成岩作用过程中孔隙度和渗透率的演化，以了解沉积盆地中盖层的形成。 这种盖层分布广泛，对油气运移和成藏起着重要作用。
