The Advanced Geodrilling Techniques in China

hina is a country with vast territory and rich in mineral resources in the world. It has along history in mining and drilling. It is well known that the churn drill was invented by Chinese at the ancient times 221B. C. In the long process of history, the drilling techniques havemade considerable progress and have now entered the advanced rank around the world.Since the P. R. of China was established, the amount of drilling has increased rapidly.More than a few hundred million meters have been drilled for geoexploration. A lot of mineralresources were discovered, and thousands of mining industries were developed all over the country. It played an important role for promoting economic prosperity and national construction inChina.During the recent years, the advanced geodrilling techniques of China is expressing in thefollowing mainly:(1)The application of geodrilling technology is growing with each passing days. In additionto the mineral prospecting, it is extending to the engineering geology, hydrogeology, environmental geology, geblogical hazard, shallow oil and gas, ground water, geothermal and scientificdrilling, etc. (2)Popularized the advanced drilling methods and techniques such as synthetic diamonddrilling, wireline core drilling, hydro - hammer drilling, multitech air and foam drilling, directional drilling and high quality drilling fluids, etc.(3)A series of drilling equipment has been designed and manufactured, including shallowsampling drills I mineral core drills, engineering drills, water well drills as well as foundationconstruction equipments, which not only meet the requirements of domestic markets, but alsoexported to abroad.Looking forward to the 2000''s and the next century, a bright future of the drilling industryis bound to follow the rapid advance in earth science and modern social construction, especiallythe requirement of mineral resources will be increasing continuously,and geodrilling techniqueswill be also developing permanently. The sphere of service is an undertaking of wide scope.
