Cluster perforation technology is one of the key technologies to improve the fracturing and transformation effect of unconventional oil and gas reservoirs.This article introduces the current research status of cluster perforation technology and explores its development direction.Taking mainstream shale gas reservoirs as an example,this paper analyzes the application cases and effects of perforation parameters in cluster perforation.The future development direction of cluster perforation research should pay more attention to the integration of geological engineering,combined with artificial intelligence to carry out refined segmented clustering andflow limiting optimization,pay attention to the factors of cluster perforation well casing variation and temporary plugging fracturing well perforation optimization,and develop new directional and perforation tools.The improvement of multi cluster fracturing well perforation technology can further assist in maximizing the effectiveness of fracturing transformation.
