摘要： 准噶尔盆地北三台地区发育多个不整合面,根据其成因机制、剖面形态等,可划分为削截不整合、超覆不整合、断褶不整合和平行不整合4种类型。风化剥蚀程度的不均一性使不整合具有典型的层状结构,包括底砾岩及水进砂体、风化粘土层及半风化淋滤带。不整合的类型控制着不整合面的倾角与交汇程度,进而控制了油气的运移及成藏模式。

Abstract: There exist multiple unconformities developed in Beisantai area of Junggar basin. They can be divided into truncation unconformity, onlap unconformity,fault-fold unconformity and parallel unconformity in terms of their forming mechanisms and section configurations. They are of typical laminar textures due to uneven weathering and denudation processes,including basal conglomerate,transgres-sive sand body,weathered claystone and semi-weathering leached zone. It is such unconformable types that control the dips and intersecting extent of unconformities, followed by controlling the hydrocarbon migration and patterns of hydrocarbon accumulation here.

Key words: Junggar basin, Beisantai oilfield, unconformity, hydrocarbon accumulation, hydrocarbon migration
