摘要
Abstract
The surface geological conditions in the piedmont of Longmen Mountain are complex,and the shallow surface velocity and thickness vary greatly,which brings great difficulties to the shooting,reception,and static correction.Surface in-vestigation directly affects the imaging effect of underground media.In order to obtain accurate static correction data for seis-mic exploration in this area and provide the basis for well-depth design,the surface investigation methods suitable for this area are studied.Combined with the working principles of geological profile,shallow earthquake,small tomography,surface micro logging,drilling coring,high-density electrical method,and three-component resonance surface investigation methods,differ-ent methods are compared,and the application effects of different investigation methods are analyzed.Through the comparison of different surface investigations,the application scope of different methods is analyzed,which provides a basis for the selec-tion of appropriate surface investigation methods and method parameters and provides a reference for surface investigation in other complex surface areas.关键词
