The invention discloses a mechanical pipe-through tool for oil and water wells, which belongs to the field of oil and gas field equipment. The device comprises: the second end of the pull rod (26) is located in the upper casing (27), and the second outer edge (431) provided on the first end of the first pressing cap (43) is clamped on the upper casing (27). On the first end, the position except the second outer edge (431) in the first pressure cap (43) is connected with the inner wall of the upper casing (27); the second end (271) of the upper casing (27) is connected with the core rod The first end (21) of (2) is connected; The first mounting part (28) is connected with the side wall of the first blind hole that the second end of the pull bar (26) is provided with, and the second mounting part (29) is connected with the upper casing ( 27), the second end of the first pin (30) is located in the second through hole, the second end of the second pin (38) is located in the first groove, and the second end of the third pin (39) in the second groove. The invention can improve the efficiency of passing through the pipe and the efficiency of unblocking.
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...
