在正生长断层遮掩部位的地震数据中会出现假构造,断层上盘时间构造呈滚动状地至断层,再往深部不存在这样的滚动.这种现象在德克萨斯湾海岸Frio 组地层的勘探中遇到过,该处一个大的生长断层扩张了 Frio 之上的一厚层低速页岩.分别位于地震控制两端的两个激发速度测量,显示了跨越勘探区目的层位的相当大的平均速度梯度.假设第一次及其后一的另一次速度测量在整个地区是有效的,它可以将井中的数据转化为时间,则在地震数据的构造解释中产生迥然不同的结果.更加明显的解释要求是有一个倾向西北向,且在目的层位中具有一个向下滚动的背斜的断层.该解释是先已由时间构造峰值上的一口干井验证过,它还否定了在这 Fake structures occur in the seismic data of the growing masonry fault, and the fault disk time structure is rolling to the fault, and then there is no such rolling in the deep part of the fault. This phenomenon occurs in the Frio Formation on the coast of the Texas Bay Encountered during exploration, where a large growth fault dilated a thick, low-velocity shale over the Frio.The two excitation velocities, measured at each end of the seismic control, showed a rather large Average velocity gradient. Assuming that the first and subsequent velocity measurements are valid across the region, it is possible to translate the well data into time, which results in disparate results in the structural interpretation of the seismic data. Is interpreted as having a fault that is predominantly NW-trending and has a downward-sloping anticline in the target horizon.This interpretation was first validated by a dry well on the top of the time-structure peak and it was also rejected
