摘要:松辽盆地西部斜坡区北段坳陷层发育5个次级近北东向构造带,自东向西依次分别为白音诺物构造带、
二站构造带、阿拉新构造带、江桥鼻状构造带及西部超覆地层尖灭带。构造演化划分为3个阶段:斜坡发育锥
形阶段、斜坡继承性发育阶段、斜玻抬升稳定阶段。发育5种构造样式,分别为反向正断层控制的鼻状构造或
背斜、正断层控制的断块构造、逆神走滑断层控制的鼻状构造、基底凸起和断块继承性发育的鼻状构造或背斜、
地层超覆构造。构造带控制油气聚集带形成,构造样式制油气藏类型,枃造长轴展布方向与砂体的展布共同
控制油气富集程度

Abstract Five sub-class near-ne structure belts are developed from east to west in the depressed layers of the
northern section of West Slope of Songliao Basin: Baiyinnuole, Erzhan, Alaxin nose, Jiangqiao
and lithologic pin
chout belt. Structural evolvement ean be divided into three phases: slope embryo development phase, slope succes
sive development phase, slope risen and stabilized phase. Five kinds of structural styles are developed: nose-like
structre or anticline controlled by reverse normal faults, fault block structure dominated by normal faults, nose
strueture determined by inverse slip faults, successively-developed nose structure or anticline controlled by basal
heave and fault blocks and stratigraphic overlap structure, The formation of oil and gas enriched zones is controlled
by the structural belts, the types of oil and gas reservoir are determined by the structural styles, the enriched degree
of oil and gas is mutually dominated by the spread directions of the long tectonic axis and the distribution of the
sand bodies
Key words: structural bell; structure style; hydrocarbon reservoir formation; the northern part of West Slope
