运用Miall的构型（Architecture）分析法，以库车河地表剖面三叠系黄山街组中部砂体三维构型为模式，将与之成因类型相似的塔北覆盖区三叠系辫状三角洲砂体划分出不同级别的界面和构型单元，并将其非均质性分为4个级别。A级为区域级非均质性，由六级界面控制，延伸范围十几到几十千米以上，宏观上控制了砂体的分布及规模；B级为亚区域级非均质性，多由五级界面控制，延伸范围几到十几千米，造成同一构造或构造带不同部位油气产能的巨大差异；C级为局部级非均质性，由四级界面控制，延伸范围几十到几百米，为非渗透性及低孔渗构型单元对流体的封隔和阻碍；D级为构型单元内部的小范围非均质性，由三级以下界面控制，延伸范围及厚度不大，与构型单元内部的岩性变化、孔渗变化及成岩作用等因素密切相关。4个级别的非均质性不同程度地对油气富集起着控制作用。
Using Miall’s Architecture analysis method, taking the three-dimensional configuration of the sand body in the central Triassic Huangshanjie Formation of the Kuqahe surface profile as a model, the Triassic braided delta sands Body is divided into different levels of interface and configuration unit, and its heterogeneity is divided into four levels. Grade A is a regional heterogeneity controlled by six levels of interface, extending over a dozen to several tens of kilometers or more, controlling the distribution and size of the sand body macroscopically. Grade B is subregional heterogeneity Controlled by a five-level interface, extending from a few to more than ten kilometers, resulting in a huge difference in oil and gas production capacity in different parts of the same structure or structure. Grade C is a local-level heterogeneity controlled by a four-level interface and extends from tens to A few hundred meters, for the impermeable and low porosity osmosis unit fluid confinement and obstruction; D-type configuration unit within the small-scale heterogeneity, controlled by the following three levels of interfaces, the extension of the scope and thickness of the It is closely related to lithology, permeability change and diagenesis in the structural units. The four levels of heterogeneity play a controlling role in oil and gas enrichment to varying degrees.
