摘　　要：湖北潜江凹陷张家湖地区具有较好的成藏条件,其位于储层发育有利相带为汉水三角洲前缘水下分流河道、滨浅湖亚相沉积,局部为半深湖亚相。然而地面条件复杂,受张家湖、大苏湖、东荆河等影响,地震资料品质较差,无法进行地震储层预测。因此搞清本区地质构造,科学建立地质模型,满足一定的面元尺寸要求,选取合理的炮检距,分析适合工区的观测系统属性,进行采集参数论证,采取符合条件的观测系统。Hubei Qianjiang depression Zhang lake region has better forming conditions,the favorable development of reservoir facies in the Han River delta for the underwater distributary channel,and shallow lake facies sediments,the local semi-deep lake.But the ground is complicated by Zhang lake,big lake Su,Dongjin and other affected poor quality seismic data,seismic reservoir prediction can not.So to make clear the geological structure, the scientific establishment of the geological model,the panel size to satisfy certain requirements,choose reasonable offset,of suitable working area of the observing system properties is collected parameters judgement,observing systems to meet the requirements.

关 键 词：地质模型 面元尺寸 参数论证 信噪比 最大炮检距
