Abstract

The invention provides a power device and a drilling and grinding tool, the power device comprises a driving shaft assembly, the driving shaft assembly is provided with a circulation channel and a plurality of circulation holes, the first end of each circulation hole is communicated with the circulation channel, and the second end of each circulation hole extends to the peripheral wall of the driving shaft assembly; the second end of each circulation hole deviates from a preset angle relative to a corresponding preset radial line in the circumferential direction of the driving shaft assembly; the outer side of the driving shaft assembly is sleeved with the outer shell part, and the outer shell part and the driving shaft assembly are arranged at intervals; liquid entering the circulation channel flows out through the multiple circulation holes so as to generate driving force on the shell part or the driving shaft assembly, then one of the driving shaft assembly and the shell part is of a stator structure, the other one of the driving shaft assembly and the shell part is of a rotor structure, and the rotor structure is used for being connected with a drilling and grinding device or a flushing device. The power device solves the problem that a driving mode adopted by a drilling and grinding tool in the prior art is inconvenient to construct.

Description

technical field [0001] The invention relates to the field of drilling and grinding tools, in particular to a power device and a drilling and grinding tool. Background technique [0002] Oil and gas wells will produce sand or scale during the production process. With the accumulation of production time, if not treated in time, wells with severe sand production or scale are prone to sand plugging, sand burial, and tubing scale blockage. channel problem. [0003] In order to avoid the above problems, the production string must be flushed and desanded in time. The currently used string cleaning tools are mainly divided into flushing and drilling. [0004] Flushing tools are used to pump liquid into the flushing string through the wellhead after the flushing string is lowered into the production string, and the liquid is ejected from the nozzle of the flushing tool at the end of the flushing string to wash and circulate the sand or dirt in the pipe out of the wellhead; The tool...
