Embodiment Construction
[0010] Such as Figures 1 to 4 As shown, a special-shaped guided fishing device for multi-fishing automatic storage. The fishing device body is provided with a guide claw 1, a lower locking wheel 2, a fishing body 3, a fishing arm 4, and a locking mechanism for controlling the action of the fishing arm 4. The wheel 5 and the fishing arm 4 are hinged on the fishing main body 3 and unfolded by a spring. The fishing head assembly 6 is connected below the fishing arm 4. A fishing claw 7 that can move up and down is provided in the shell of the fishing head assembly 6 , the salvage claw 7 acts as a locked state, and acts as an unlocked state. It is characterized in that the salvage claw 7 is provided with a pin shaft 8 protruding from both sides of the shell of the salvage head assembly 6, and the salvage body 3 accommodates the salvage In the groove of the head assembly 6, there is an unlocking slope 9 that cooperates with the pin shaft 8 on the fishing claw 7. The main body 3 of ...

The invention discloses a multi-fishing automatic storage special-shaped guide type throwing and fishing device and relates to petroleum machinery. A salvage clamping jaw (7) is provided with pin shafts (8) extending out of two sides of a shell of a salvage head assembly (6); an unlocking inclined plane (9) matched with a pin shaft (8) on the salvage clamping jaw (7) is arranged in a groove, for accommodating the salvage head assembly (6), of a throwing and salvage main body (3); the throwing and fishing main body (3) is provided with a blanking plug storage bin (10) below the fishing head assembly (6); after the fishing head assembly (6) grabs a blanking plug (11), when the blanking plug (11) is contained in the containing groove of the throwing and fishing body (3), the fishing clampingjaw (7) moves upwards and loosens the blanking plug (11) through cooperation of the unlocking inclined face (9) and the pin shaft (8), and the blanking plug (11) is put into the blanking plug storagebin (10) below. The device has the advantages of being reasonable in structural design and high in working efficiency, and a plurality of blanking plugs can be fished out through one-time well descending operation.
Description
technical field [0001] The invention relates to petroleum machinery, in particular to a special-shaped guided fisher with a plurality of plugging storage units. Background technique [0002] The water injection in the oilfield is injected in layers, and the injection volume of different water injection layers is different, and each water injection layer is correspondingly equipped with a water distributor. A water distributor has a water distributor main body, the diameter of the inner channel of the water distributor is 46, the diameter of the eccentric channel is 20, and a stopper is housed to adjust the water injection volume. The water injection in the oil field needs to adjust the water injection volume, so the replacement of the plug is a necessary work. At present, the existing fish thrower can only fish one blocker in one operation, and the operation efficiency is very low. Due to the huge number of wells in the oil field, the testing workload is correspondingly la...
