The progress of the revision of geological drilling technology standard system in recent years in China

In the past decade, great progresses have been made in drilling technology standards formulation and revision for land and resources industry. The sub-systems of drilling technical standards are established with scientific classification, rational structure and clear level. A number of drilling technical standards have been revised and the aged standards have been improved. Because drilling technology is related to the geological prospecting sectors of geology and mineral resources, metallurgy, coal, nonferrous metals, nuclear industry, Armed Forces of Gold, chemical industry and building materials, the quality and efficiency of resources evaluation can be improved by using advanced drilling technical standards, which is conductive to environmental protection, energy saving and pollutant reduction. In China, the technical strength has been continuously increased in drilling research and development departments and manufacturing enterprises in recent years, and the improved research test conditions provide favorable conditions for the drilling technology standardization.
