Development of TQ508-70Y hydraulic casing tongs with big caliber and high torque |
| |
| Abstract: | The current kinds of casing power tongs made in our country can not meet the requirement of increasing operation in big borehole and ultra-deep wells through they can meet the demand of ordinary drilling operation.In this regard,TQ508-70Y hydraulic casing tongs with caliber of 244.5-508 mm and maximum torque of 70 kN·m are developed.The main parts of the tongs include tong head,drive gear shell,variable speed mechanism,hydraulic system and hydraulic range measurement equipment.The test and application results show that the tongs are characterized by reliable performance and high operating efficiency and can meet the demand of casing-pump operation.Every parameter of the tongs meets the design demand and is in accordance with SY/T 5074-2004 industry standard. |
