【摘要】：近年来,"源-汇"研究已逐渐成为沉积学领域颇为关注的重要课题。系统梳理了国内外"源-汇"系统研究取得的新进展,分析总结了沉积体系"源-汇"研究思路与多方法综合分析技术,并指出了"源-汇"系统研究未来的发展趋势。大陆边缘盆地沉积体系的"源-汇"研究集中于沉积事件的触发机制和沉积物的搬运过程,复杂陆相断陷盆地在储层预测方面创新形成了"源-汇"时空耦合控砂原理及相应的控砂模式。"源-汇"研究将多方法物源示踪分析应用于古源区恢复与古水系重建中。针对陆相断陷盆地局部物源背景下的"源-汇"系统,潜在剥蚀区的层序地层学精细研究恢复了隐伏物源区地质历史时期的真实面貌。"源-汇"系统要素的定量化表征与储层的定量预测正在逐步探索之中,建立从源到汇的定量响应关系是最终目的,而在"源-汇"系统定量化约束下的沉积过程模拟,为少井条件下储层预测提供了有力支持。重视物源体系研究、定量化储层预测、多学科、多方法融合、过程化与机制化研究,形成工业化应用标准是未来沉积体系"源-汇"研究的发展趋势。
[Abstract]:In recent years, the study of "source-sink" has gradually become an important subject in the field of sedimentology. This paper analyzes and summarizes the research ideas of "source-sink" of sedimentary system and the multi-method comprehensive analysis technology. The future development trend of "source-sink" system is pointed out. The "source-sink" study of sedimentary systems in continental margin basins focuses on the triggering mechanism of sedimentary events and the transport process of sediments. In reservoir prediction of complex continental faulted basins, the space-time coupling sand control principle of "source-sink" and the corresponding sand control model have been formed. The study of "source-sink" applies multi-party source tracer analysis to the restoration of paleoprovenance and paleodrainage systems. In the course of reconstruction. Aiming at the "source-sink" system in the local provenance background of continental faulted basin, The fine study of sequence stratigraphy in the potential denudation area has restored the true appearance of the geological history of the hidden material source area. The quantitative characterization of the elements of the source-sink system and the quantitative prediction of the reservoir are being explored step by step. The establishment of quantitative response relationship from source to sink is the ultimate goal. However, the simulation of sedimentary process under the quantitative constraint of "source-sink" system provides a strong support for reservoir prediction under the condition of few wells. Multidisciplinary, multi-method fusion, process and institutional research, and the formation of industrial application standards are the future development trend of the "source-sink" research of sedimentary system.
