Practice and discussion of on-site preventive maintenance of TDS-1000A top drive
At present,as one of the key drilling equipment of offshore oil drilling platforms,the top drive has become a standard product of the oil drilling industry.It can directly rotate the drill pipe from the upper space of the derrick and feed it downward along the special guide rail to complete a variety of drilling operations,such as rotary drilling of the drill pipe,circulating drilling fluid,connecting pipe-stands,making up and breaking out pipes,and back-reaming,and has the advantages of safe production,improving operational efficiency,and effectively preventing drilling accidents.During the daily use process,it is necessary to carry out regular preventive maintenance according to the running time.However,due to the compact production rhythm of the drilling platform,the overhaul of the top drive sometimes cannot be carried out in the workshop.Therefore,on-site overhaul often becomes its second choice.To improve the on-site maintenance methods,enhance the maintenance quality,and save the maintenance period,this paper discusses and analyzes the steps,methods,and matters for attention in the on-site overhaul of TDS-1000A top drive according to the author's work practice.
