The invention discloses a mechanical pipe dredging tool of an oil-water well, and belongs to the field of oil and gas field equipment. According to the mechanical pipe dredging tool, the second end ofa pull rod (26) is located in an upper outer sleeve (27), a second outer edge (431) arranged at the first end of a first press cap (43) is clamped at the first end of the upper outer sleeve (27), andthe portion, except the second outer edge (431), in the first press cap (43) is connected with the inner wall of the upper outer sleeve (27); the second end (271) of the upper outer sleeve (27) is connected with the first end (21) of a core rod (2); and a first mounting portion (28) is connected with the side wall of a first blind hole formed in the second end of the pull rod (26), a second mounting portion (29) is connected with the inner wall of the upper outer sleeve (27), the second end of a first pin (30) is located in a second through hole, the second end of a second pin (38) is locatedin a first groove, and the second end of a third pin (39) is located in a second groove. According to the mechanical pipe dredging tool, the pipe dredging efficiency and the clamping release efficiency can be improved.
Description
technical field [0001] The invention relates to the field of oil and gas field equipment, in particular to a mechanical pipe-through tool for oil and water wells. Background technique [0002] In the process of oil and gas field development, scales often occur in oil and water wells. In order to ensure the normal use of oil and water wells, it is necessary to descale the inner walls of oil and water wells to realize pipe passage. [0003] related technologies, such as figure 1 As shown, the through-pipe tool includes a weighted rod 01 , a suspension joint 02 , a swivel joint 03 and a spiral guide cone 04 . The suspension joint 02 is axially provided with a first through hole and a second through hole communicating with each other, and the diameter of the first through hole is larger than the diameter of the second through hole. The first end 011 of the weighted rod 01 is located in the first through hole and connected with the first through hole, the first part of the swiv...
