分频反演技术在泌阳凹陷井楼-高庄地区的应用
|
摘要
在泌阳凹陷井楼-高庄地区,随着油气勘探的不断进展,该地区为三角洲前缘砂体,多物源,砂体比较薄,平面上变化大,地层产状较陡,制约了勘探进程。为此,利用分频反演技术对该区块的三维地震资料进行了测井约束反演,拓宽了地震资料的频带,大大提高了地震资料的分辨率,反演数据体的分辨率在5m左右,地震资料的反演处理能够客观地反映地下砂体的分布。
For oil and gas exploration in Jinlou-Gaozhuang Area of Biyang Depression,it was a delta front sandbody,where sources were of great varieties,sandbody was thin,areal changes were big with steep occurrence,these controlled the exploration progress.Thus frequency reverse technique was used for 3D data process of logging constraining reverse,it widened the band of seismic data process,improved resolution of seismic data with its resolution about 5m.the data process can objectively reflect the sand distribution.
