摘　　要：古水深分析对古环境重建、盆地分析、层序地层学研究、古地貌恢复以及生、储、盖层条件的评价都有重要意义。古水深分析通常有古生物法、沉积学法、地球物理法、地球化学法及数字模拟法,各种方法优缺点并存,尽管某些方法在特定地质条件下存在优势,但在恢复同一环境的古水深时,不同方法还是存在其偏差;这些方法多以定性为主,许多方法易受自然条件限制,且对样品可靠性要求高,一定程度上限制了古水深研究。古水深恢复建议综合考虑地质背景、环境演化、研究地质体特征及地质资料情况等多种因素,多方法研究相互约束,以期更客观地再现古水深变化规律。The analysis of paleo-water depth is of great significance in fields such as paleo-environment reconstruction,basin analysis,sequence stratigraphy studies,reconstruction of ancient landform,and the evaluation of source,reservoir,and cap rock conditions.Paleo-water depth analysis methods usually include paleontological,sedimentological,geophysical,geochemical,and digital simulation methods,each with their own strengths and limitations.Although some methods have advantages in a specific geological background,there are some deviations between different methods in reconstructing paleo-water depth in the same environment.These methods are mostly qualitative,easily restricted by natural conditions and require the samples of high reliability,which limits paleo-water depth research to a certain extent.Therefore,when analyzing paleo-water depth,it is suggested to comprehensively consider various factors such as geological background,environmental evolution,geological characteristics,and geological data,and to adopt multiple methods to study mutual constraints,in order to jointly explore the law of Paleo-water depth variation in the target layer.
