This paper focuses on the rapid leakage blocking technology for oil pipeline leaks, introducing its types, principles, and effectiveness. The research indicates that traditional hot-work leakage blocking methods carry significant risks and are likely to cause safety accidents. In comparison, non-hot-work pressure leakage blocking technology is more favorable. Examples include intelligent plugging robots and modular sealing systems, which adopt new technologies and materials, greatly enhancing the safety performance and efficiency of pipeline leakage blocking. When long-distance pipelines transport oil products, leaks can result in oil loss, subsequent environmental pollution, and even the risk of fire and explosion. The oil pipeline emergency repair process outlined in this paper mainly includes leak monitoring, leak point location, graded leakage blocking, support provision, and post-repair inspection. The study presents technologies such as temporary wooden wedge plugging, high-pressure clamp plugging, non-stop pressure bypass plugging, and patch repair. It provides reference value for conducting pipeline emergency repairs and improving work efficiency and safety.
