摘    要:近代沉积学的诸多进步都是由比较沉积学推动的,它对沉积学的发展有重要意义。目前,其被广泛应用于相模式的推断和沉积相带、储层及其非均质性的预测。比较沉积学是利用比较对象所选变量的时空展布建立模型,再利用模型推断预测被比较对象因变量时空展布的沉积学分支学科。它是根据比较沉积学类比原则,在自生旋回、他生旋回识别的基础上开展的或然性推理。完整的比较沉积学工作过程必然存在2个步骤——比较建模和推断预测。其研究方法包括相模式分析法、几何形态分析法、沉积物载荷分散体系分析法和模拟重构法4种,这些方法多与层序地层学方法联合使用。本文根据比较沉积学的原理和方法综合分析了历年来的典型成果。未来比较沉积学将开展更多与边界条件有关的研究、多尺度统一解释的研究,进一步加强量化,提高预测精度的研究。

Abstract:Many aspects of Sedimentology are promoted by Comparative Sedimentology in recent eras, which shows the great significance of Comparative Sedimentology to the development of Sedimentology. At present, it is widely used in the inference of the facies models, the prediction of sedimentary facies belts,and the prediction of reservoirs & their heterogeneity. Comparative Sedimentology is a branch of Sedimentology, which uses the selected variables of the compared object to build its spatio-temporal model, and further to predict the distribution of the dependent variables. Two steps should be included in a complete Comparative Sedimentology process:comparative modeling and inferential prediction; in other words, according to the analogy principle of comparative sedimentology, probability reasoning is carried out on the basis of identifying natural cycles and induced cycles. Its research methods include the local facies pattern analysis, the geometric morphology analysis, the sediment loading dispersion system analysis,and the simulation reconstruction, which are normally combined with sequence stratigraphy. The typical research results in recent decades have been comprehensively analyzed on the basis of the principles and methods of Comparative Sedimentology. It can be predicted that the further research of Comparative Sedimentology will concentrates on boundary conditions, multi-scale unification, and quantification to improve prediction accuracy.
Keywords:Comparative Sedimentology  characteristics  classification  principle  conception definition  research status
