The perforation technology of oil and gas well refers to the use of special energy gathering equipment, the use of explosives in the specific layer of the hole to burst the metal jet, shooting through the casing, cementing cement and stone ring and reservoir, which is known as the “front foot” of oil and gas exploration and development. After decades of development, a series of perforation technologies have been formed, such as high temperature and high pressure perforation, deep penetration shaped perforation, composite perforation, constant plane/oriented/constant angle perforation, full pass perforation, dynamic negative pressure perforation, pumping perforation, cluster perforation etc. The continuous development and application of these perforation technologies has improved the perforation efficiency, increased oil and gas production, and can better protect the reservoir and extend the production life of the reservoir. This paper focuses on the analysis of common oil and gas well perforation technology at home and abroad, and prospects the future development of oil and gas well perforation technology in China.
