DZ/T 0227-2010 Geological core drilling regulations
Abstract
This regulation stipulates the technical requirements and relevant management provisions for all processes of drilling construction.
In this regulation, the definition of "core" is broad, referring to all types of rock samples that can be collected, including not only cylindrical cores but also various rock blocks, rock samples, and rock chips. Therefore, various reverse circulation continuous coring operations are also included in the scope of core drilling.
This regulation is mainly applicable to geological core drilling, engineering survey, engineering construction, hydrological well drilling, and oil and gas well drilling of small-diameter boreholes. It can be referenced for these operations.
This regulation is applicable to drilling operations with a hole depth of less than 3,000 m.
