摘要:
吐哈盆地受博格达山和觉罗塔克山所夹持,盆地内广泛发育以周缘山体为物源的冲积扇群,冲积扇群内砾岩层具有横向展布范围广、厚度和速度变化大的特点,严重制约下覆构造的准确落实。因此理清冲积扇结构及砾岩层空间分布和速度变化特征,对下覆构造形态和构造高点位置的准确落实尤其重要。研究表明吐哈盆地火焰山南北两翼浅表层砾岩扇群具有纵向低速砾岩层和高速砾岩层叠置,横向受古凸起分割、古水流控制,呈多物源发散状扇群展布特征,此次通过岩性录井、测井、地震反射特征识别和属性分析,刻画了砾岩扇体空间展布,用以指导地震资料处理工作具有助于浅表层速度模型建立,对于进一步提高地震资料成像品质和准确落实下覆构造形态至关重要。
Abstract:
The Tuha Basin is sandwiched by the Bogda and Jolotak Mountains,and the alluvial fan groups with the surrounding mountains as the source are widely developed in the basin. The conglomerate layers in the alluvial fan groups are characterized by a wide lateral spreading range and large variation in thickness and velocity,which seriously restrict the accurate implementation of the underlying structures. Therefore,it is especially important to clarify the spatial distribution and velocity variation of alluvial fan structures and conglomerate layers for the accurate implementation of the underlying tectonic patterns and the location of tectonic highs. The study shows that the shallow surface conglomerate fan group in the north and south flanks of the Huoyan Mountain in the Tuha Basin is characterized by the superposition of low-velocity conglomerate layers and high-velocity conglomerate layers in the vertical direction,and is controlled by ancient uplift segmentation and ancient water flow in the lateral direction,showing a multi-source dispersion fan group distribution. Through lithological logging,logging,seismic reflection feature identification and attribute analysis,the spatial spread of conglomerate fans was carved out to guide the establishment of a shallow surface velocity model for seismic data processing,which is essential to further improve the imaging quality of seismic data and accurately implement the underlying tectonic morphology.
