摘要
恢复地层剥蚀厚度是定量研究盆地演化史和进行油气资源定量评价的重要基础工作。由于传统剥蚀量恢复方法具有局限性,因此新兴起了许多新的地层剥蚀量恢复方法,如磷灰石裂变径迹分析法、沉积波动过程分析法、流体包裹体法和宇宙成因核素分析法。叙述了它们的基本原理并辅以实例说明了它们在实际应用过程中的步骤和优缺点。指出应根据研究区具体的地质特征选择适当的方法,并可尝试综合使用多种方法进行相互验证。
Denuded strata recovery is the important work of basin evolution study and oil/gas evaluation quantitatively. Because of the restriction of traditional denuded strata recovery methods, a few new denuded strata recovery methods rise up, such as thermal annealing of fission tracks in apatite, depositional and erosional processs, and cosmogenic nuclides analysis. In this paper,the principles of each method have been illustrated and specific steps and advantages and disadvantages are also illustrated based on the examples. Different denuded strata recovery methods are suitable to different study areas, and comprehensive denuded strata recovery methods are also good choices.
