The top drive running & pulling casing device is a dedicated device used for running & pulling casing operation or casing drilling drive, it is based on the top drive drilling system and integrates mechanical and hydraulic technologies. Targeting at different specifications of casing, this device has been formed as serialization products with two structures (inside caliper and outside caliper), it is applicable to running & pulling casing operations of various different casing wall thickness. It can replace the widely used running & pulling casing devices in domestic and abroad currently, such as casing tong and so on, it can give full play to the advantages of top drive, it can not only realize the automatic connection of casing string but also provide the capability to rotary lower the casing and circulate the mud; the safety risks of running & pulling casing sticking and blocking have been dramatically reduced, the success rate of running & pulling casing operation has been evidently improved, it provides the equipment guarantee to smoothly run the casing into specified depth and reduce the personnel requirement of running & pulling casing at the same time, it has properties of safety and high efficiency.
