Abstract
Three-ball fisher belongs to oil salvage equipment technical field. In the process of oil field production, various tools would fall into the well, such as drills, logging equipment, sucker rods, etc, which require corresponding fisher to salvage these tools. The three-ball fisher is a safe and reliable salvage device with new structure and high success rate. An ordinary similar tool, such as steel balls, seizes the fish by downward deadweight. If mud or mud cake in the track sticks down the steel ball, the steel ball would not go downward, resulting in salvage failure. To address the problem, the tool adds a spring on the steel ball, forcing the steel ball go downward to seize the fish. The small hole on the bullnose enables liquid in the track to flow out smoothly so that the steel ball could move freely in orbit with no instantaneous vacuum which could prevent the movement of the steel ball. Because of the wrong operation, the ground fast joint will often inadvertently fall into the drilling tool the tool could get the joint out by adding an anti-dropping ring (6).
Description
Technical field
The utility model relates to a kind of three ball fishing tools, belongs to the technical field of oil fishing tool.
Technical background
In oilfield process, various tool can often be arranged, fall in the well as drilling tool, logger, sucker rod etc., this just need have corresponding instrument that it is salvaged, a kind of fishing tool that three ball fishing tools are exactly a kind of safe and reliable, novel structure, success rate is high.
Summary of the invention
The purpose of this utility model is to provide a kind of reliable fishing device.
The purpose of this utility model is achieved in that a kind of three ball fishers are made up of plug, spring, body, steel ball, guide shoe, anti-lost ring, fittings body.Its special character is: (a) the body lower end is equipped with guide shoe and is convenient to fish and enters body.(b) body has three or five holes that have from trivial angle, and steel ball moves in the hole, on move its inscribed circle and increase fish is entered, move down its inscribed circle and reduce engagement with the fish.(c) there is spring the steel ball upper end, gives downward thrust of steel ball all the time.(d) the spring upper end links with plug, is convenient to the location and the taking-up of spring, has inner hexagonal hole to be convenient to loading and unloading on the plug, and has aperture to be convenient to liquid discharge inflow.(e) anti-lost ring is arranged in the fittings body, falling into drilling tool as snap joint can propose.
Usefulness of the present utility model is simple in structure, and processing cost is low, because of having spring roof pressure steel ball, can make steel ball clench fish, fishing success ratio height, and maintenance easily.
Description of drawings
Accompanying drawing is a cross-sectional view of the present utility model.
The specific embodiment
As accompanying drawing, guide shoe (5) is loaded on the body (3), and three or five self-locking holes are arranged in the body (3), steel ball (4), spring (2), plug (1) are housed in the hole, body (3) links with fittings body (7), and fittings body (7) links with drilling tool, and anti-lost ring (6) is housed in the fittings body (7).
When fish enters body (3) under guide shoe (5) effect, steel ball (4) promotes to move on the lower edge self-locking track fish, and fish is allowed into body (3), on carry fittings body (7), steel ball (4) is spring (2) and the frictional force effect lower edge self-locking track locking fish that glides, on carry drilling tool and pull fish out.As very snap joint not being fallen in the drilling tool, anti-lost ring (6) can be taken it out of ground when proposing drilling tool.
Claims (1)
- A kind of three ball fishers are made up of plug (1), spring (2), body (3), steel ball (4), guide shoe, (5), anti-lost ring (6), fittings body (7), it is characterized in that: (a) body (3) lower end is equipped with guide shoe (5) and is convenient to fish and enters body (3); (b) body (3) has three or five holes that have from trivial angle, and steel ball (4) moves in the hole, on move its inscribed circle and increase fish is entered, move down its inscribed circle and reduce engagement with the fish; (c) there is spring (2) steel ball (4) upper end, gives (4) downward thrusts of steel ball all the time; (d) spring (2) upper end links with plug, is convenient to the location and the taking-up of spring (2), has inner hexagonal hole to be convenient to loading and unloading on the plug (1), and has aperture to be convenient to liquid discharge inflow; (e) in the fittings body (7) anti-lost ring (6) is arranged, falling into drilling tool as snap joint can propose.
