Abstract

The invention relates to the technical field of oil and natural gas drilling, in particular to a tube tool centering device. The tube tool centering device comprises a foundation support fixedly connected with a mounting foundation, drive oil cylinders movably connected with the foundation support through support lugs on the foundation support, a transition bracket movably connected with the drive oil cylinders and the foundation support and centering plates movably connected with the foundation support and the transition bracket respectively. The tube tool centering device is simple in structure, small in size and high in centering accuracy.

Description

technical field [0001] The invention relates to the technical field of oil and natural gas drilling, in particular to a pipe centering device. Background technique [0002] Drill pipes, drill collars and casings are indispensable tools in oil drilling operations. In oil drilling, drill pipes and drill collars are used when drilling well holes, and casings are used when strengthening the well wall to speed up drilling operations. , it is usually necessary to connect multiple drill pipes, drill collars and casings in advance and store them inside the derrick fingerboard. In advanced drilling rigs, this kind of rooting operation is often automatically completed by a series of equipment. During the rooting operation process Among them, the pipe centering device is used to straighten the pipe so that the two pipes to be connected can be aligned. [0003] Existing centering device is made up of support, driving oil cylinder, centering arm, connecting rod and bearing pin. The two...
