Abstract:

The paper mainly describes the characters of the structure and geography based on the drilling equipments of the geothermal resource in Yunnan Province, and introduces drilling technology and method used recently. Some problems existed in the work daily, such as drilling bits types selected, hole-protecting and hole-cementation, water stop and so on, are analyzed. Some sugestions on improving geothermic drilling technology in Yunnan Province are put forward.

Key words: geothermal resource, drilling technology, Yunnan Province
