In recent years, with the continuous development of science and technology and the continuous progress of people's living standards, the domestic demand for oil is also increasing. Because of this, higher requirements are put forward for the drilling technology of petroleum engineering. How to do well in the research and innovation of petroleum engineering drilling technology has become an important topic of great concern to all walks of life. In this paper, combined with personal practical work experience, starting from the status quo of China's petroleum engineering drilling technology, the researchers analyzed the main technology of petroleum engineering drilling, and finally put forward the future development trend of petroleum engineering drilling technology, in order to play a useful reference for the research and analysis in Petroleum Engineering fields.
