Abstract
The utility model discloses a special device for fishing roller bits in oil wells. The device consists of an upper joint (1), a steel shell (2), a circulating water tank (3), a steel inner wall (4), a fisher inner chamber (5), a fishing claw collection and release chamber (6), a fishing claw (7) and a drill bit (8). The device is characterized in that the upper joint (1) is arranged on the top of the steel shell (2); the circulating water tank (3) is arranged between the steel shell (2) and the steel inner wall (4); the drill bit (8) is arranged on the bottom of the steel shell (2); and the fishing claw collection and release chamber (6) is arranged on the bottom of the steel inner wall (4), and the fishing claw (7) is arranged on the inner edge of the bottom of the fishing claw collection and release chamber (6). The device can be used for effectively fishing the roller bits falling into oil wells.
Description
Technical field
The utility model relates to oil drilling tools fishing operation field, especially relates to the special-purpose fishing device of a kind of oil well rock bit.
Background technology
At present, known technology is to falling into rock bit in oil well owing to there is no Special fishing tool, usually adopt diamond to wear away drilling tool it is ground, and grinding a drill bit needs more than half month usually, and cost is high, waste time and energy.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of oil well rock bit special-purpose fishing device,
Using this device to salvage fast and effectively and falling in oil well is rock bit.
The technical scheme that its technical problem that solves the utility model adopts is: adopt the special-purpose fishing device of a kind of oil well rock bit, this device by top connection, steel shell, circulating water chennel, steel inwall, fisher inner room, drag for and grab retractable room, bailer grab, drill bit and form, it is characterized in that: the top at steel shell arranges top connection, and its effect is to be convenient to be connected with upper drilling string.Between steel shell and steel inwall, circulating water chennel is set, its effect is to be convenient to circulation well cleanup in fishing.Bottom at steel shell arranges drill bit, is used for the rock bit that falls in well is guided to the fisher inner room.Drag in the bottom setting of steel inwall and grab retractable room, drag for the bottom inward flange of grabbing retractable room arrange can freedom retractable bailer grab, its effect is that the rock bit that will salvage is introduced the fisher inner room, and blocks the inner room outlet, prevents that the object by salvaging that enters the fisher inner room from coming off.Use this device to salvage safely and effectively and fall into the interior rock bit of oil well.
The beneficial effects of the utility model: by field trial, the utility model compared with prior art uses this device just successfully to salvage a rock bit within one day, and is safe and reliable, time saving and energy saving, can improve the salvaging efficient of rock bit, reduces and salvages cost.
