沉积相、层序地层学对碎屑岩早期成岩作用的影响及控制

Effect and Control of Depositional Facies and Sequence Stratigraphy on the Early Diagenesis of Clastic Rocks

通过对国内外大量碎屑岩早期成岩作用研究成果的调研,把成岩过程的类型和分布与沉积相及碎屑岩旋回的层序地层格架结合起来,详细探讨了在不同沉积微相及层序地层格架下成岩作用的区别,并将沉积相与层序地层有机联系起来,综合考虑其对成岩改造的影响及控制作用,为碎屑岩储层的预测及评价提供了有利的依据。

Early diagenesis of clastic rock,an important research field,has been given extensive attention along with the improvement of exploration and development of energy resources and modern testing techniques.This study investigates a great number of researches on early diagenesis of clastic rocks from domestic and abroad,and links the types and distribution of diagenetic processes to the depositional facies and sequence-stratigraphic framework of clastic successions,in order to discuss the diagenesis distinctions among different depositional facies and sequence-stratigraphic frameworks.At the same time,links them together and considers their effects and controls on diagenesis alteration,to provide advantageous proof for prospecting and evaluating clastic reservoirs.
