Abstract
The utility model discloses a lance is dragged for to slider formula for oil gas development, including main part, spliced pole and guide block, be provided with piston chamber and foundation in the main part, inside the main part was seted up in the piston chamber, foundation integrated into one piece is connected in the main part bottom, spliced pole integrated into one piece is connected in the main part top, the guide block welds in the foundation bottom. The utility model discloses can relax and salvage the tubulose foreign matter in the pipe wall, effectively improve oil field development efficiency.
Description
Technical Field
The utility model relates to a lance is dragged for to slider formula for oil gas development belongs to fishing lance technical field.
Background
The fishing spear is an inner fishing tool, can be used for fishing falling objects with inner holes, such as drill pipes, oil pipes, milling pipes, liner pipes, packers, water distributors, production accompaniers and the like, and can also be used for carrying out back-off operation on the falling objects meeting the blockage or being matched with other tools; the fishing spear structure that uses at present is complicated, maintains inconveniently, and the slider notch takes place blocking phenomenon very easily, seriously influences fishing efficiency. In order to solve the problems, a new technical scheme is provided.
Disclosure of Invention
An object of the utility model is to provide a lance is dragged for to slider formula for oil gas development to solve the problem that provides in the above-mentioned background art.
In order to realize the purpose, the utility model adopts the following technical scheme: the utility model provides a lance is dragged for to slider formula for oil gas development, includes main part, spliced pole and guide block, be provided with piston chamber and foundation in the main part, inside the main part was seted up in the piston chamber, foundation integrated into one piece connects in the main part bottom, spliced pole integrated into one piece connects in the main part top, the guide block welds in the foundation bottom.
Preferably, the connecting column is internally connected with an air receiving port through threads, and the air receiving port is communicated with the piston cavity.
Preferably, the piston rod has been nested to piston intracavity portion, the welding of piston rod bottom has the push pedal, the push pedal is 45# steel matter, and is the triangle-shaped structure.
Preferably, the two sides of the bottom column are nested with sliding blocks, the outer ends of the sliding blocks are provided with anti-skidding grooves, and the two sides of the inner ends of the sliding blocks are fixedly provided with return springs through screws.
Preferably, the guide block is 45# steel and has a solid conical structure.
Compared with the prior art, the beneficial effects of the utility model are that: the air receiving port of the utility model is communicated with the piston cavity, so that the air pressure can be easily injected into the piston cavity; a piston rod is nested inside the piston cavity, so that the piston rod can easily slide along the piston cavity; the outer end of the sliding block is provided with an anti-slip groove, so that the friction force between the sliding block and the inner wall of the foreign body can be increased; the two sides of the inner end of the sliding block are fixedly provided with a return spring through screws, so that the sliding block can be easily driven to return; the guide block is in a solid conical structure, and can effectively guide and balance the main body; the bottom of the piston rod is welded with a push plate, so that the sliding block can be easily pushed.

in the figure: 1-a body; 2-connecting a column; 3-a guide block; 4-a piston cavity; 5-a bottom pillar; 6-air receiving port; 7-a piston rod; 8-pushing the plate; 9-a slide block; 10-a return spring.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely explained below with reference to the drawings in the embodiment of the present invention.
As shown in fig. 1-3, a lance is dragged for to slider formula for oil gas development, including main part 1, spliced pole 2 and guide block 3, is provided with piston chamber 4 and sill pillar 5 in the main part 1, and inside piston chamber 4 seted up in main part 1, sill pillar 5 integrated into one piece connected in main part 1 bottom, and spliced pole 2 integrated into one piece is connected in main part 1 top, and guide block 3 welds in sill pillar 5 bottom.
The specific use mode is as follows: the air receiving port 6 is connected with an air pipe, then the main body 1 is placed in the oil pipe, at the moment, the main body 1 is driven by the gravity of the guide block 3 to move to the upper part inside the tubular foreign matter along the inner wall of the oil pipe, then the air pipe is opened to drive air to flow into the piston cavity 4, meanwhile, the air in the piston cavity 4 drives the piston rod 7 to move downwards, the piston rod 7 moves downwards to drive the push plate 8 to move downwards and be embedded between the inner ends of the slide blocks 9, and the slide blocks 9 move outwards relatively after being pushed to extrude the inner wall of the tubular foreign matter; finally, the main body 1 is lifted up to take the tubular foreign bodies out of the oil pipe.
The foregoing is a preferred embodiment of the present invention, and for those skilled in the art to understand the teaching of the present invention, the changes, modifications, replacements and variations to the embodiments will still fall within the protection scope of the present invention without departing from the principle and spirit of the present invention.
