摘要

通过对大庆长垣中部杏树岗、高台子和太平屯构造扶杨油层的断裂和砂体展布特征分析认为，扶杨油层的断裂与砂体具有相互作用关系，即同沉积断裂对砂体的展布具有控制作用，河道沉积的砂体对断裂形成具有制约作用。断裂与砂体的相互作用对扶杨油层油气运移和成藏具有重要意义，同沉积断裂控制的砂体以垂向向下排烃为主，形成低部位成藏模式，河道砂体与其诱导的断裂共同构成了垂向向上和侧向运移的通道，形成高部位成藏模式。

Abstract

The analysis of fractures and distribution characteristics of sand bodies in Fuyu reservoir of Daqing placanticline shows that the interaction between fractures and sand bodies exists. Synsedimentary fractures have controlling role on the distribution of sand bodies and the sand bodies in river channel sedimentation have restrictive functions on the forming of fractures. The interaction between fractures and sand bodies has great significance for hydrocarbon migration and reservoir-forming in Fuyu reservoir. Sand bodies controlled by synsedimentary fractures mainly expulse vertically down and the reservoir-forming patterns are low position accumulation. Sand bodies in river channel and induced fractures form the pathways of vertical migration and lateral migration and the reservoir-forming patterns are high position accumulation.
