Description
Technical field
This utility model belongs to oil, natural gas and cbm development field, and in particular to a kind of cable transmission Pressure breaking bullet
Dedicated buffering resistance absorber.
Background technology
Caseless cartridge high enegry gas fracturing is oil, well volume increase, the effective means of augmented injection, in recent years as drilling technology is swift and violent
Development, oil, well, coal bed gas well hole deviation are continued to increase, and are often occurred from kickoff point (KOP) wink when causing cable transmission Pressure breaking bullet
Between big resistance collision Pressure breaking bullet, cause that Pressure breaking bullet sealing is destroyed to cause miso-fire accident（Ignition success rate is for without shell
It is a unalterable quota to play High-Energy Gas Fracturing Technology）；Single guide shoe can only solve the stream in whole transmitting procedure from well killing fluid
Body resistance reduces, and cannot buffer moment from the borehole wall, kickoff point (KOP) big resistance, effective protection body；There are some special dresses
Put, after Pressure breaking bullet burning, bottom hole falling article is excessive and volume causes greatly pit shaft pollution, and pit shaft pollution needs well-flushing, large volume
Junk needs to salvage to discharge not only to waste time and energy and also increases follow-up expense, has been not suitable for market demands.
Utility model content
The purpose of this utility model is to provide a kind of cable transmission Pressure breaking bullet dedicated buffering resistance absorber, existing single to solve
Guide shoe cannot buffer moment big resistance in transmitting procedure and cause Pressure breaking bullet seal break-off problem to the impact of Pressure breaking bullet.
This utility model is employed the following technical solutions：A kind of cable transmission Pressure breaking bullet dedicated buffering resistance absorber, including guide shoe,
Resistance balance cylinder, connecting rod is provided with above guide shoe, and connecting rod is located at the inner chamber of resistance balance cylinder, and connecting rod sleeve has spring, the bullet
Spring is coaxial with resistance balance cylinder, connecting rod；The small end is connected with plug, is provided with sideboard in the lower end of connecting rod, activity
Baffle plate is moved up and down in resistance balance cylinder.
Used as further improvement of the utility model, the inner edge of the sideboard is enclosed within the bulge loop at the top of the guide shoe
On, the bottom of the sideboard and the guide shoe) at the top of leave gap.
Used as further improvement of the utility model, the upper end of the resistance balance cylinder is connected with overhead gage, the upper gear
Plate is connected with the plug.
As further improvement of the utility model, in connecting rod lower end equipped with pad and nut.
Used as further improvement of the utility model, the height of the resistance balance cylinder is 50mm, a diameter of 67mm.From knot
Reduce big fitting dimension to reduce bottom hole falling article on structure.
Used as further improvement of the utility model, the height of the guide shoe is 74mm, a diameter of 74mm.Subtract from structure
Little big fitting dimension is reducing bottom hole falling article.
This utility model principle is as follows：When being subject to moment resistance to impact in transmitting procedure, lower end is compressed in the resistance balance cylinder
Spring upwards motion moment resistance point through later, the spring in compression releases energy makes guide shoe and sideboard reset, effectively slow
Effect of the moment resistance to Pressure breaking bullet is rushed, Pressure breaking bullet is protected, such as met moment resistance this process again and repeat；Simultaneously because
The streamlined structure of guide shoe 11 reduces the fluid resistance of well killing fluid in transmitting procedure, and increases transmission speed, improves and applies
Work efficiency rate；Resistance balance cylinder, sideboard, overhead gage employ aluminum alloy materials, guide shoe for nylon material, and these are that buffering subtracts
Resistance device large scale accessory they can burn down with Pressure breaking bullet, reduce bottom hole falling article to greatest extent, reduce pit shaft pollution,
Well-flushing, salvaging need not be organized after high enegry gas fracturing to save time and expense, adapted to the market demand.
This utility model cable transmission Pressure breaking bullet dedicated buffering resistance absorber, in high enegry gas fracturing site operation, improves
Ignition success rate and Pressure breaking bullet transmission speed, reduce bottom hole falling article, reduce pit shaft pollution, save the engineering time
With follow-up expense, simple structure is easily assembled, low production cost.

Specific embodiment
It is described in further detail below with reference to Figure of description and specific embodiment.
A kind of cable transmission Pressure breaking bullet dedicated buffering resistance absorber, including guide shoe 11, is provided with resistance balance above guide shoe 11
Cylinder 7, connecting rod 6, connecting rod 6 are located at outside the inner chamber of resistance balance cylinder 7, connecting rod 6 and are cased with spring 5, the spring 5 and resistance balance cylinder 7,
Connecting rod 6 is coaxial；6 upper end of the connecting rod is connected with plug 3, is provided with sideboard 8 in the lower end of connecting rod 6, and sideboard 8 is in resistance
Move up and down in surge drum 7.The inner edge 81 of sideboard 8 is enclosed within the bulge loop 111 at the top of the guide shoe 11, sideboard 8
