项目摘要
Despite considerable research over the last two decades on the origin of diagenetic fluids involving dolomitization, the debate about the process/ mechanism of dolomite formation is still is ongoing, especially regarding timing of fluid flow and chemistry of these fluids and the extent to which massive dolostones formed in near surface environments as opposed to formation at variable burial depths by hydrothermal and burial processes. The present proposal is part of an ongoing research program, both conceptually and experimentally, on the chemistry, source(s) of diagenetic fluids and timing of fluid flow events in sedimentary basins. It is aimed to put special emphasis on fault and fracture diagenesis, because faults and fractures are often the primary conduits for diagenetic fluids, whether passively or actively. These fluids do not only result in fracture mineralization but may also induce important diagenetic modifications to the host carbonate rocks, such as dissolution, recrystallization and dolomitization. Quantification of the fluid flow using integrated field, structural, petrographic and geochemical tools can be also used to develop conceptual models for the spatial and temporal distribution and connectivity of reservoir porosity and permeability on a regional basinal scale. The proposed research program for the next 5 years will have the following objectives: (1) a better quantification of the main diagenetic events and their responsible originating fluids in sedimentary basins; (2) determination of the relationship between the fractures and deformational or tectonic events (i.e. fracture diagenesis); (3) geochemical simulation of fluid/rock interaction (e.g. using reactive transport modeling); (4) determination of patterns of paleo-fluid flow (e.g. numerical and geochemical modeling); (5) investigate the application of Mg-isotopes and clumped isotopes on source(s) for dolomitizing fluids and temperature-fluid composition relationship; and, (6) unravel the impact of diagenetic events porosity evolution. These objectives can be achieved through careful examination of textural parameters, mapping of regional and local distribution of diagenetic and structural components, geochemistry (stable and radiogenic isotope measurements, fluid inclusions), burial and thermal history curves and quantitative basin modeling techniques. Sampling from carbonate reservoirs and their outcrop analogs from different geologic settings (stable intracratonic areas vs. tectonically more active areas within the basin) will allow a better understanding and quantification of the origin, timing and spatial distribution of dolomites and other diagenetic phases within each setting. Comparative studies on paleo-fluid flow and diagenesis will also be carried out between the Western Canada Sedimentary Basin (WCSB), Michigan Basin and Middle East basins.
尽管近二十年来对白云岩成岩流体的成因进行了大量的研究,但关于白云岩形成过程/机制的争论仍在继续,特别是关于流体流动的时间和这些流体的化学作用,以及大量白云岩在近地表环境中形成的程度,而不是通过热液和埋藏过程在不同埋藏深度形成的白云岩。本建议是正在进行的关于沉积盆地中成岩流体的化学、来源(S)和流体流动事件的时间的概念和实验研究计划的一部分。它的目的是特别强调断层和裂缝的成岩作用,因为断层和裂缝往往是成岩流体的主要通道,无论是被动的还是主动的。这些流体不仅导致裂缝成矿,而且可能对寄主碳酸盐岩进行重要的成岩改造,如溶解、重结晶和白云石化作用。利用综合野外、构造、岩石学和地球化学工具对流体流动进行量化,也可以用来建立概念模型,在区域盆地尺度上研究储集层孔隙度和渗透率的时空分布和连通性。未来5年的研究计划将有以下目标:(1)更好地量化沉积盆地中的主要成岩事件及其负责的原始流体;(2)确定裂缝与变形或构造事件(即裂缝成岩作用)之间的关系;(3)流体/岩石相互作用的地球化学模拟(例如,使用反应输运模拟);(4)确定古流体流动模式(例如,数值模拟和地球化学模拟);(5)研究镁同位素和块状同位素在白云石化流体来源(S)和温度-流体组成关系中的应用;(6)揭示成岩事件对孔隙度演化的影响。这些目标可以通过仔细检查结构参数、绘制成岩和构造成分的区域和局部分布图、地球化学(稳定和放射性同位素测量、流体包裹体)、埋藏和热历史曲线以及定量盆地模拟技术来实现。从不同地质环境(稳定的克拉通内部区域与盆地内构造较活跃的区域)的碳酸盐岩储层及其露头类似物中取样,将有助于更好地了解和量化每种环境中白云岩和其他成岩阶段的成因、时间和空间分布。还将对加拿大西部沉积盆地(WCSB)、密歇根盆地和中东盆地进行古流体流动和成岩作用的比较研究。
