【摘要】 公道桥地区构造运动剧烈,造成地层速度纵、横向上变化大,同时由于缺少深层井资料,影响了构造研究的精度。本文利用地震叠加速度,参考地质、测井资料采用D IX公式建立空间速度场。构建虚拟深井对中古生界速度场进行标定,取得较好的效果。更多还原

【Abstract】 Due to intense tectonic movement,obvious vertical and lateral changes of stratigraphic velocity in Gongdaoqiao area.Also without deep well,these factors affect the accuracy of structural interpretation.The integration of stack velocity,geological and log data,with Dix formula,the space velocity filed is established.Use fabricated deep well to demarcate Mesozoic-Paleozoic Velocity Field and achieve satisfactory results.更多还原
