高转速/低钻压/大泵量的全面钻进孕镶金刚石钻头
Comprehensive drilling impregnated diamond bit under high rotate speed/low wob/large pump output
摘要
Abstract
Applying and research status of comprehensive drilling with impregnated diamond bit at rotate speed/low wob/large pump output was reviewed.A"calculus"rock breaking model under the drilling condition had been put forward preliminarily,with the nature of abrasive wear and bit corrosion compared to rock breaking process.Results showed that during rock breaking,rotation speed mattered the most,followed by wob and pump output.And when it came to matrix wear,the rank would be pump output,rotation speed and wob,from most influencial to least.In diamond wear,rotation speed and pump output both had higher effect than wob.关键词
