Bao Steel high toughness drill pipe deep exploration of 8038m

• Recent news coming from the Tarim oilfield, steel, Baosteel Steel Division for PetroChina Tarim oilfield X9.19 mm 127 mm s-Ultra-NC52 of high toughness drill pipe, at 902-8038 m successful drilling, breaking the 2011 years g Baosteel drill pipe in Tarim oilfield 8023 meters deep well 7 create the oil deep magic record and become a milestone in the Chinese-made drill pipe.
  Tarim oilfield is recognized worldwide as one of drilling oil on top level. 902 is the Tarim oilfield is deployed in an appraisal well of kelasu tectonic zone in kuqa, complex geological structure, drill pipe serving in extremely harsh conditions. For user proposed of in strengthened drilling parameter Xia improve drilling speed, and reduced drilling cost of needs, Baosteel super high toughness drill team Yu 2012 up, and Tarim oilfield expert together, from drill material, drill tube body, and joints, and weld of heat treatment process and the drill using technology, aspects started series technology research, ensure drill of tube body, and joints, and weld are can reached super high toughness requirements, effective improve has drill of overall impact toughness, meet has user in strengthened drilling parameter Xia improve drilling speed of needs. Eventually the wells just 368 days deep-8038 m, not only refreshed 2011 is on the same tectonic belt of deep 7 g 8023 oil deep record created by the well, while deep 7 g wells drilled 748 days save for 380 days, 50.8% faster.
  902 well drilling success, marking China's drilling technology for Super deep, high temperature, high pressure deep onto a new level, also means that Baosteel in China applies pioneered a comprehensive grasp of more than 8000 metres of drill pipe for ultra-deep drilling of core technology for domestic ultra-8000 meters of depth drilling has accumulated valuable experience.
