摘要
Abstract
The investigation and failure analysis were made on one drill lifting sub of one oil field.It was considered that the main cause of the tripping failure of the lifting sub was the insufficient connection strength of the fine round thread fittings.Such fine round thread fittings and its measure gauge had been abandoned by API standard,but there was no standard for drill lifting subs at home and abroad at that time.In order to solve the tripping problem of lifting subs,a new technical specification was put forward,and then lifting subs standard for oil and gas industrial standard (SY/T 5699—1 995)and API specification was established.The standard was applied all over the world with good effect so far.关键词
