Alloy Steel&Nickel Alloy Centre Spear Wireline Fishing Tools
I. Overview:
The outer wire spear is used to catch the broken wire in the
tubing.
The outer fishing spear is an fishing device composed of a male
buckle top part and a welding elastic tip on the fishing rod. The
tip piece is welded with a tip strip to form a hook shape to grasp
the end of the broken steel wire that has formed a hook loop. When
the wire breaks under the packing box, an integral object such as a
slotted barrel wire finder must be inserted before lowering the
fishing spear to determine the position of the broken end and smash
it into a ball.
II. Technical parameters:
Size | Fishing neck | Connection |
1.5" | 1.375" | 15/16"-10UN |
1.875" | 1.75" | 1-1/16"-10UN |
2.5" | 2.313" | 1-1/16-10UN |
III. Structural features and use:
1. There are many sizes and models of steel wire outer spears, and
different inner spears can be selected according to different
tubing sizes.
2. If the spear is more than one or two meters above the tip of the
wire and then the wire is caught, the wire may accumulate on the
top of the spear and the wire cannot be caught. When the spear is
fishing the wire, attach the rope cap to the spear and then connect
it to the RB fishing tool to go down the well. Once the spear is
entangled by the steel wire, it can be thrown away at the RB with
an upward shock.
IV matters needing attention:
Before using the outer wire spear, the wire finder must first be
lowered to form the wire nest in the well to facilitate the smooth
fishing of the inner spear.
