摘要
Perforation is a key link in well completion. To meet the development requirements of different types of oil and gas fields, after over ten years of research and development, a series of perforation methods and matching processes have been established, such as deep penetration shaped perforation, composite perforation, directional perforation etc, which on the one hand improve the result and efficiency of perforation completion and stimulation, on the other hand prolong the service life of reservoir by protecting the reservoir. Meanwhile, the optimization of perforation design and the improvement of perforation check method further enhance the safety and success rate of perforation, and make the perforation test process and field application more standardized. For unconventional tight oil and gas reservoirs, deep-ultra-deep reservoirs, thin and poor reservoirs, reservoirs with edge or bottom water, staged fracturing of horizontal wells, and re-perforating of old wells, perforation techniques such as 3D perforation, ultra-deep penetration perforation, and high temperature high pressure perforation, and supplement perforation etc should be studied according to the features of the specific oil and gas reservoir and well. ©, 2014, Science Press.
