【摘要】 在塔里木盆地轮台地区三维工区内,通过应用层位自动追踪技术、相干数据体和水平切片等多种手段,对本区内的主要地质层位(苏维依组、巴什基奇克组、卡普沙良群和三叠系顶面)进行了精细构造解释,落实了小断块与低幅构造圈闭。同时,开展了本区横向变速分析,并建立高精度的速度场,完成了准确的顶面构造图。更多还原

【Abstract】 In the Luntai 3D work area of Tarimu Basin of Northwestern China,we carefully interpreted geological strata(Suweiyi Formation,Bashenjiqike Formation,Kapushaliang Group and top-Triassic) and ensured the small fault blocks and low-rising structure traps exactness using Horizon Auto Tracking,coherence data volume and horizontal seismic slice,and so on.Meanwhile,we analyzed the variation of lateral velocity in this area and completed exact top structure maps by building 3D high precise velocity field.更多还原
