Scientific drilling is an effective way for human beings to explore the interior of the earth, it is also an important means to solve major problems such as resources, disasters and the environment. Scientific drilling projects in the United States, the former Soviet Union, Germany, Japan, Iceland, China and other countries are summarized. The problems in drilling and completion of 10000-meter scientific ultra-deep wells are discussed, including complex geological conditions, high formation temperature, long drilling cycle, difficult well deviation control, etc.. Future applications of geology-engineering integration technology, high-efficiency rock breaking technology, high-temperature drilling fluid technology, and many others in the drilling and completion of 10000 meter scientific ultra deep wells are also prospected.
