摘要:

构造运动、沉积作用和气候变化具有一定的周期性,导致沉积物在时间、空间上具有旋回性,垂向上具有分段性和周期性,平面上具有分带性,因此,沉积地层是具有层次的。依据这一原理,层次的划分由低级到高级划分为 9级层次。根据盆地演化、古生物、同位素及地质年代资料,将盆地基底或盖层作为 1级层次,界、系、统为2、3、4级层次,这是进行油气储层划分的基础。根据露头、岩芯、地震、测井资料在第 4级层次内划分出第 5级层次(层序);继而根据高分辨率层序地层学原理在第 5级层次内可划分出第 6、7级层次(中、短期旋回)。最后,根据储层建筑结构层次分析原理和方法在第 7级层次内再划分出 8、9级层次(单一成因砂体、复合成因砂体)。层次的解释应在充分运用事件地层学、泥砂运动力学、现代沉积、露头调查、模拟实验的基础上,对沉积过程和层次成因作出合理解释。层次对比应遵循先低级后高级、先区域后局部及等时对比的原则,力求使各种地层对比、划分方法有机结合起来,取长补短,达到精细研究储层的目的。

Abstract:

There are several methods of stratigraphic division and correlation,but they have their own systems,virtues and shortages.Through the research of chronostratigraphy,sequence stratigraphy,high-resolution straigraphy and architectural element analysis,combined with the character of hierarchy of stratigraphy,this paper expected to establish the rule and method of oil and gas reservoir hierarchy division,hierarchy description,hierarchy interpretation and hierarchy correlation from global scale to reservoir scale.

Key words: hierarchy division, hierarchy correlation, sequence stratigraphy, high-resolution sequence stratigraphy, architectural element, oil gas reservoir
