摘　　要：依据国内外最新研究成果目前丘形反射解释的难点主要集中在构造作用形成的基底差异升降或海底滑塌的条带状延伸丘状体;水动力成因的丘状体,深水水道或冲沟内部轴向延伸的丘状体;沿陆坡侵蚀而成的等深流残丘和等深流水道、碳酸盐岩台地周缘斜坡的漂积体;沉积物活化引起的丘状体,由液化砂岩、塑性泥岩、盐岩上侵而成;多种因素共同作用而成的丘状体四个方面。基于此,对地震剖面上丘形反射解释的难点和误区进行分析,旨在为相关领域的研究提供借鉴。According to the latest research results at home and abroad,the current difficulties in the interpretation of hump reflection mainly focus on the banded extended hump formed by tectonic process of basement differential uplift or submarine slump.A dune of hydrodynamic origin,extending axially within a deep water channel or trench;Isobaric residual mound and isobaric channel formed by erosion along the continental slope,and the drift deposits of the slopes around the carbonate platform;Mounds caused by sediment activation are formed by upwelling of liquefied sandstone,plastic mudstone and salt rock.A variety of factors work together to form four aspects of the mound.Based on this,the difficulties and errors in the interpretation of hummock reflection on seismic section are analyzed,aiming at providing reference for the research in related fields.
