Abstract:In compiling areal isopach of a basin from seismic horizon structure map,we can use the residual thickness at both sides of fault plane to show the horizontal distribution of a fault,Whether the equivalents at the both sides of the fault plane of a normal fault contact each other or not,the residual thickness values are lower in middle part and higher in both sides,The boundary fault and pinch-out should be located according to the major limit structure map,Besides,the structure maps compiled by different people or in different time should be checked and modified so as to guarantee their accuracy and completeness.
