Types of Structural Slope break Zone and Its Controls on Sand Bodies and Hydrocarbon of Huhehu Depression in Hailar Basin

摘要

摘要: 呼和湖凹陷为“东断西超”的箕状断陷，断陷期广泛发育的构造坡折带对砂体及油气的富集起到重要的控制作用，对其研究将对该区的下步勘探具有重要意义。根据断裂发育特征及平面、剖面组合样式，在该凹陷识别出多种同沉积断裂组合样式，主要包括平行断阶状、帚状、叉状、断接型等断裂体系，造就湖盆复杂多变的构造古地貌及断裂坡折体系，严格控制着凹陷内砂体分散体系的沉积和堆积模式。按照所发育的断裂坡折带分布位置，分别阐述了断控陡坡型坡折带、缓坡断阶型坡折带、洼槽边缘型坡折带三种构造坡折带对沉积充填及沉积体系的控制作用。结合勘探实践探讨了同沉积断裂坡折带控制的砂体与油气藏富集的关系，指出洼槽边缘断裂坡折带是最为有利的勘探部位。

Abstract: Huhehu depression is a half graben rift which is down
faulting along the eastern boundary and overlapping along the western boundary. Huhehu depression is a half graben with the form of eastfaulting and westoverlapping. The structural slopebreak zone which is widely developed in depression period plays a key role in the sand bodies and the accumulation of hydrocarbon. The study in this area is significant for further exploration. According to the fracture developing characteristics and their assemblage styles in plane and profile, many syndepositional fracture assemblage styles are identified in the depression. The fracture system mainly includes the forms of parallel faulted step, brush, fork, breaking of contact, and so on, which built up the complicate structural palaeogeomorphy in lake basin and its fracture slopebreak system, and which strictly controlled the deposition of sand bodies and their pilingup patterns in the depression. In accordance with the distribution of the fracture slopebreak zone, this paper presents the control effects of three structural slopebreak zonesfaultcontrolling steep slope, faultedstep gentle slope and depression margin for sediment infilling and sedimentary system.Based on the exploration practice, the paper discusses the relation between accumulation of hydrocarbon and the sand bodies which were controlled by syndepositional fracture slopebreak zone. It points out that the fracture slopebreak zone of depression margin is the most favorable exploration area.
