合理地选择激发条件是应用炸药震源进行陆上地震勘探中首要的一环。本文结合BW地区三维地震勘探的实例，对工区潜水面和表层地质条件进行综合研究，提出了用微测井结合小折射、井口τ值结合微测井等研究表层地质条件的实际工作方法，探讨了松南地区如何选择合理的激发条件以及岩性勘探中如何选择激发因素。
Reasonable choice of excitation conditions is the primary link in the on-the-ground seismic exploration using dynamite sources. Based on the three-dimensional seismic exploration in BW region, this paper makes a comprehensive study on the diving surface and surface geological conditions in the work area, and puts forward the practical working methods of studying the surface geological conditions by micro-logging combined with small refraction, wellhead τ value and micro-logging. How to choose reasonable excitation conditions in Songnan area and how to choose the stimulating factors in the lithologic exploration.
