摘　　要：泌358区块位于泌阳凹陷南部陡坡带边界断裂附近的栗园地区,受边界断裂活动影响,该区块为一个鼻状构造,核三段为快速堆积的砂砾岩沉积,储层非均质性强,甜点储层分布范围不清楚。为了提高砂砾岩体的滚动勘探开发效果,从砂砾岩扇体期次划分入手,通过储层地震响应特征分析,基于砂砾岩沉积机理对地震资料进行纹理特性处理,利用灰度能量属性刻画有利相带。结果表明,扇中亚相发育多条近南北向水道,向前推进距离受水道长度控制,甜点储层主要发育于扇中亚相。Located in Liyuan area near the boundary fault in southern steep slope zone of Biyang Sag,affected by the boundary fault activities,Bi 358 block is a nose-shaped structure with fast accumulation of conglomerate deposits in the third member of the core.The reservoir is highly heterogeneous and the distribution of sweet spot reservoirs is unclear.In order to improve the rolling exploration and development effect of sandstone and gravel rock mass,starting from the division of sandstone and gravel fan stages,through the reservoir seismic response characteristics analysis,the texture characteristics of seismic data are processed based on the sedimentary mechanism of sandstone and gravel,and favorable facies zones are characterized using grayscale energy attributes.The results indicate that there are multiple nearly north-south trending waterways developed in fan subfacies,the forward distance is controlled by the length of the waterways and the sweet spot reservoirs are mainly developed in the fan subfacies.
