Invention effect
The technical effects of the invention are that：
Due to being designed using main dress (high temperature) medicine 17 of fast burn rate, the action time is not in the device for main dress (high temperature) medicine 17
More than 2s, it can be achieved that in pipe string in work progress of going into the well, the residual air in interlayer oil pipe is excluded, improves the pressure transmission effect of device
Rate.
As a result of 24 designs are plugged, plugs 24 diameters and be more than I box cupling minimum step hole internal diameter, it is high in the combustion chamber
Under thrust body of calming the anger effect, piston rod 19 moves to 7 minimum step hole step of I box cupling with boosting disk 23 together with plugging 24
Position, plug 24 be hampered after detached with piston rod 19, boosting disk 23, and block the drainage hole of 7 side wall of I box cupling, improve device
Pressure transmission efficiency.
It is designed as a result of boosting disk 23,23 diameter of boosting disk is slightly less than interlayer pipe aperture, straight by increasing push-plate
Diameter can reduce the energy loss that liquid reflux is brought, and promote the pressure transmission efficiency of piston component 6.
Due to being designed using the IIth box cupling 8, it can be achieved that blocking piston component 6, prevents piston component 6 long in interlayer oil pipe
Distance movement, which is hampered, to be blocked.
It is designed as a result of Section III box cupling 9, box cupling side wall is equipped with and the spiral shell of the stifled a diameter of 6mm being threadedly coupled of rubber
Pit can select liquid filling mode, artificial liquid filling that need to screw on the stifled implementation of rubber according to wellbore fluid clean level and fluid cushion height
Well head liquid filling, it is stifled, it can be achieved that pipe string in work progress of going into the well, is poured into from trend interlayer oil pipe that automatic liquid filling need to screw off rubber
Well liquid, while, it can be achieved that after supercharging device effect, high pressure well liquid being discharged in time, to protect oil pipe safe to use.
It, can be by the way that 21 quantity of shear pin in piston component 6 be arranged, to adjust piston due to being designed using piston component 6
The pressure value that component 6 is pushed out, the pressure value determine that device can be transferred to the pressure value of next stage pressure blasting device.If
The shear pin 21 of 5~20 same diameters is set, shear pressure is from 15~60MPa etc., to the output of regulating device output end
Pressure；
Due to being designed using the dress main charge 17 of fast burn rate, powder burning in oil/gas well interlayer propagation of explosion high temperature pressurised device
Aerogenesis surge pressure≤110MPa afterwards can generate pressure at next stage pressure blasting device (at 100 meters away from device interlayer oil pipes)
Power difference≤60MPa meets the requirement of certain high pressure hole condition.
Due to using the design of relief valve 5, well head being facilitated to dismantle, releasable device internal cause fortuitous event, such as：Solid propellant
Failure or shear pin quantitative design are wrong, and the gas pressure of generation fails to push piston component movement, i.e., combustion chamber has been suppressed centainly
Pressure, can pass through relief valve implement ground pressure release.
7 present invention are an interlayer explosion propagation devices for being resistant to higher temperature, are emitted from its priming system items powder charge and main dress
Medicine selects high temperature resistant powder charge, can be used in deeper well, use scope is wider
8 detonation waves transmitted by higher level's perforating gun are used as the exciting energy resource of product, easy to use.
9 devices are mounted with a piston apparatus that output pressure can be adjusted according to condition of construction, are lived by adjusting pressure
It fills in diameter and adjusts the pin numerical value on pressure piston, achieve the effect that adjust output gunpowder pressure, gunpowder generates the profit of pressure
Higher with rate, pressure controllable can export, for product, it may have good safety.
Have in 10 apparatus structures it is a set of can allow the Ith box cupling of simple mechanism and the Ith box cupling that well liquid is filled automatically in interlayer,
And when can mention well head after construction, on tubing string, well liquid is released in pit shaft automatically, the labor intensity for the person that reduces construction operation
With workload.
11 have a set of safe geostatic pressure relieving mechanism, and on the body, there are one relief valves for design, can be proposed in product
Afterwards, high pressure gas of the release due to accidental cause storage in the device, improves the safety of product.
12 gunpowder action times are short, and pressure transmission is fast, and capacity usage ratio is high, and overall dosage is few, thus reduces storage
With the danger of transport.
13 carry out pressure transmission using oil pipe and liquid, reduce making for the explosives such as sandwiched perforating gun and transmission detonation joint
With improving the reliability of work progress, reduce construction cost, while also reducing the amount of labour
