Abstract
The utility model discloses an outer hook type spear capable of fishing in a receding mode. The outer hook type spear comprises a connector, a spindle shaft connected with the connector, a clamp tile arranged on the spindle shaft, and a releasing ring arranged on the spindle shaft and located at the lower end of the clamp tile. The releasing ring is provided with an outer hook connector. The outer hook connector is provided with an outer hook for fishing a cable. In fishing construction, if a fish top is a cable, the outer hook type spear can be for fishing the cable, and if the fish top is not provided with the cable, the outer hook type spear can enter an inner cavity of an oil pipe for fishing the oil pipe, thereby effectively reducing the possibility that blind feeding of the fish spear or the outer hook can cause failure drilling, and avoiding a lower lead solid fish top, and actually improving fishing efficiency and success rates.
Description
Technical field
The utility model relate to can salvage in a kind of oil-water well overhaul construction cable, again can fishing oil pipe Multifunctional fishing tool, particularly a kind of outer hook-type returnable fishing spear.
Background technology
In the overhaul construction, in the part oil-water well, junk is complicated, has the oil pipe of well, also have cable in oil pipe, and the bottom is stuck all.For this situation, can only adopt at present the mode that lance back-off fishing oil pipe combines with outer hook salvaging cable of dragging for, but the erratic behavior that breaks and take off because of cable in the salvaging process, often can not judge accurately that top of fish is cable or oil pipe, no matter drag for lance or lower outer hook under being, the possibility of running empty brill is arranged, be lowered to fishing tool after can only descending lead stamp to implement top of fish, efficiency of construction is very low again.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of can salvage cable, again can fishing oil pipe outer hook-type returnable fishing spear.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of outer hook-type returnable fishing spear comprises joint, the mandrel that is connected with described joint, is arranged on slips on described mandrel, is arranged on the release ring that is positioned at described slips lower end on described mandrel; On described release ring, outer hook joint is housed, is equipped with one on described outer hook joint for the outer hook of salvaging cable.
Preferably, described outer hook and outer hook joint screwed connection have guaranteed the coupler body bonding strength.
Preferably, screwed connection place of described outer hook and outer hook joint welding.Described outer hook and outer hook joint weld again, further strengthen the coupler body bonding strength.
The utility model is in salvaging construction, if top of fish is cable, this instrument can be salvaged cable; If top of fish does not have cable, this instrument can enter the oil pipe inner chamber, fishing oil pipe, thus drag for lance under effectively reducing blindly or outer hook causes the possibility of running empty brill, also avoided time lead stamp to implement top of fish, conscientiously improved salvaging efficient and success rate.
Description of drawings
The structural representation of the outer hook-type returnable fishing spear that Fig. 1 provides for the utility model.
The specific embodiment
From the utility model embodiment shown in Figure 1 as can be known:
The outer hook-type returnable fishing spear of the utility model, comprise joint 1, the mandrel 3 that is connected with joint 1, be arranged on slips 2 on mandrel 3, be arranged on the release ring 4 that is positioned at slips 2 lower ends on mandrel 3, discharge on ring 4 outer hook joint 5 is housed, be equipped with one on outer hook joint 5 for the outer hook 6 of salvaging cable.Outer hook 6 is arranged on outer hook joint 5 by screwed connection, and after connection, spot welding again between outer hook 6 and outer hook joint 5 has guaranteed outer hook 6 bonding strengths, prevents that coupler body from snapping the accident well that falls.
The utility model adopts the D25mm sucker rod to add the D19mm sucker rod and makes outer hook 6, and outer hook 6 bottoms are sharp-pointed, and the hook spiral rises and arranges, and external diameter is D53mm only, can enter salvaging in the D73.02mm oil pipe, guarantees that top of fish cleans out.
During construction, this outer hook-type returnable fishing spear and drilling rod connect into well, slowly transfer at distance top of fish 1-2m place, and pressurization 5-15kN, the upper lifting pipe post if suspending weight increases, illustrates that top of fish does not have cable, instrument successfully drags for and obtains oil pipe, can implement back-off; If the upper lifting pipe post, suspending weight does not obviously increase, and illustrates that top of fish has cable, can again transfer, and cable is salvaged in rotation.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other embodiment easily according to guiding theory of the present utility model, within these embodiments all are included in scope of the present utility model.
