摘　　要：在已钻遇的砂砾岩体展布范围的约束下,通过断层转换带控制砂砾岩体物源供给通道研究、地震相分析确定扇体范围、属性分析预测扇体展布等手段,对泌阳凹陷南部陡坡带发育的小型砂砾岩体进行了精细刻画。结果表明,断层转换带的位置控制了砂砾岩体的物源供给通道,影响了古地貌形态,从而形成了沟扇对应的沉积格局,混沌属性能较好地刻画砂砾岩体的分布,且砂砾岩体堆积速度越快,成层性越差,则地震相反射越杂乱,混沌属性值越高。Restricted by the spread range of the drilled sandgravel rock body,the study of source supply channel of sand-gravel rock body was controlled by the fault transition zone,the determination of sand-gravel body by seismic phase analysis,and the prediction of sand-gravel mass by attribute analysis.The results show that the fault position control of the transformation zone supply channels,the gravel rock source affected the paleogeomorphic form,thus forming a groove corresponding sedimentary framework,and the chaotic properties can describe the distribution range of gravel rock.The faster the sand and gravel mass accumulation,the worse the stratification,the more chaotic the seismic reflection and the higher the value of chaotic property.
