摘要：

Pipe sticking is one of technical challenges in the drilling industry that has a major impact on the drilling efficiency and well costs. In order to eliminate deep water stuck pipe hazards, a new type of the jet cutter cartridge is designed. The main structure of the cartridge is a linear shaped charge including hydrogen-based emulsion explosives and copper tubes. During the detonation process of emulsion explosives, the copper tubes form several linear jet cutters along the ring direction to penetrate the stuck drill pipe. Experimental results indicate that the properties of hydrogen-based emulsion explosive meet the requirement to the explosive for the environment of the stuck point. This annular jet cutter cartridge is successfully applied in a copper mine to solve a stuck pipe incident.
