The Using of Anti-Sulfur Drill Pipe in High Sulfur Oil-Gas Field
H2S existed in some oil-gas field, resulting in many drill pipe hydrogen embrittlement and stress corrosion cracking accident during the drilling, causing huge losses, particularly during blowout and pipe fall into the bottom caused by hydrogen embrittlement, would lead to serious accident .There were a lot examples in history, in view of the situation, this paper analyzed of the mechanism of the hazards of H2S to the drill pipe, proposed the technical conditions and using requirements to select anti-sulfur drill pipe. After field using, selecting the proper types of anti-sulfur drill can improve the safety of drilling. According to field application summed some attention in the process of using the anti-s drill issue to be aware of.
