松辽西斜坡地区构造特征及其控油作用
|
摘要
依据地震和钻/测井资料,结合前人研究成果,在松辽西斜坡地区展开了嫩江组—青白口组地层的构造特征研究。结果表明:西斜坡地区主要经历了坳陷期和反转期构造运动,断裂类型多样,主体呈北北东和北北西向延伸,整体规模较小。平面上,区域构造自西向东可分3个带:西部简单斜坡带,中部背斜带和东部洼陷带。研究区微幅度构造发育,中部背斜带易形成断背斜型、断鼻型和构造-岩性型圈闭。以高角度、小断距为特征的断裂多形成垂向输导通道,广泛发育的背斜-岩性类构造输导脊构成了良好的油气运移路径,沟通了东部洼陷带的烃源岩,控制着油气的聚集成藏。
This paper,based on seismic data,well logging data and previous achievements,studies the structural features of Nenjiang-Qingbaikou formation in Songliao basin's western slope,where had undergone depression and reverse tectonics with diversified fault types,NNE and NNW striking,but small size.Regional structures can be divided into three zones,eastward,western simple slope zone,central anticline zone and eastern depression zone.Small scale structures are developed with fault-anticline,fault-nose and structural-litho traps.Faults characterized by high angle and small faulted displacement and widely-spreading anticline-litho conduits form vertical channels as a good oil-gas migration path,connecting the hydrocarcon source in eastern depression and controlling the oil-gas traps.
