Specifically, fig. 1 is a schematic diagram of an installation structure of a packing, a packing box and a packing gland, fig. 2 is a schematic diagram of a structure of a packing, please refer to fig. 1 and fig. 2, in an oil and gas drilling construction process, the packing 91 is arranged in a sealing space between the packing box 93 and a polish rod 95, a seal is formed by extrusion deformation of the packing gland 94, and after the packing 91 deforms, the packing can abut against between the outer surface of the polish rod 95 and the inner surface of the packing box 93. After the pumping unit is started, the polish rod 95 reciprocates along the axis direction, and the outer surface of the polish rod 95 and the packing 91 are rubbed and abraded, so that the packing 91 is sealed and loses effectiveness. Packing 91 is sealed inefficacy and can lead to oil pipe leakage, for solving above-mentioned problem, needs regularly to dismantle the wearing and tearing packing and the new packing of installation, and operating personnel can use the packing extracting tool that this embodiment provided to dismantle the wearing and tearing packing.
The packing removal tool includes a body 10 and a drive portion 20, wherein the body 10 is configured to abut against the outer surface of the polish rod 95 such that the cutting edge 41 can be directed toward the packing 91 in the sealed space. Wherein, the body 10 can be rod-shaped or platelike, and when the packing 91 is unscrewed to the operating personnel operation blade 41, the body 10 supports against on the outer surface of the polished rod 95, provides a holding power for the operating personnel, and is convenient to operate.
