Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
Compared with DZ/T 0148-1994, this standard is subject to the following technical changes as follows.
--- Added terms and definitions;
--- Increased diamond drilling and diamond composite drilling;
--- Increased the core, sampling and geological cataloging conditions of geotechnical;
---Adding special water extraction methods to chapters, including horizontal wells and seepage wells and other water intake engineering techniques;
--- Increased technical parameters of the gravel filter and filter filter filter technical parameters;
--- Increased water well fracturing technology;
--- Added chapter on tube well detection and repair;
--- Added some new materials and new equipment operating regulations;
--- Added a common form format for drilling water wells such as drilling construction design books and drilling class reports;
--- Removed drill bit drilling, alloy drilling and particle mixing drilling, jet reverse circulation drilling, special drilling technology and drilling process, etc.;
--- The order of the chapters was partially adjusted according to the hydrological drilling procedure.
This standard was proposed by the Ministry of Land and Resources of the People's Republic of China.
This standard is under the jurisdiction of the National Land Resources Standardization Technical Committee (SAC/TC93).
