With the continuous growth of global demand for oil and gas resources, ultra-deep oil and gas exploitation has gradually become an important direction for the development of the petroleum industry. This paper aims to discuss the research progress of key technologies for drilling and completion of ultra-deep oil and gas production. This paper first summarizes the research background and importance of ultra-deep oil and gas extraction, and then analyzes the key research contents, methods, processes and achievements of current drilling and completion technologies in detail. By comparing the advantages and disadvantages of different technologies, the paper also summarizes the challenges faced by the current drilling and completion technology and the future development trend. Finally, the article lists the main references cited in the course of the research, which provides convenience for readers to further understand the field.
