Green exploration, as an advanced concept, culture and development transformation and upgrading mode, has been increasingly valued and promoted by the majority of geological work, involving well site selection, well site construction, equipment selection, construction technology and well site reclamation and green restoration. Based on the topographic and geomorphologic conditions of Tsavalong plateau in Nyingchi and the requirements of deep well electrode, the paper discusses the exploration location, drilling construction and management of small diameter geological exploration borehole and the protection of natural ecology.
