水陆过渡带地表环境复杂，表层松散而岩性多变。表层结构调查工作中，常规的井中微测井和小折射都很难达到理想的解释精度。在尼日利亚某工区的施工作业中，采用地面激发、井中接收的微测井方式，利用排列移动观测法来加密对地层的观测密度。在提高作业效率的同时又提高了低降速带的解释精度，从而建立准确的表层结构模型，为静校正提供可靠的数据。

In water -land transition zone,the surface environment is complex,and the surface layer is loose and various lithologic characters.In the surface structure survey,the conventional up -hole micro -logging and refraction can not a-chieve the desired interpretation accuracy.In the conduction operation of certain Nigeria area,the micro -logging which in-cludes shooting on surface and receiving in hole was utilized.The method of spread shifting observation was used to in-crease the observation density of formation,and improve the operation efficiency and the interpretation accuracy of low ve-locity zone.The surface structure model was established to provide reliable data for the static correction.
