Abstract
The utility model discloses a kind of perforating device with pressure, especially suitable for oil field band pressure pipeline drilling operation with pressure.It includes control valve, short circuit, drill bit, lengthening rod sleeve is connected on its control valve, lengthening in rod sleeve has an extension bar, connect with drill bit, it lengthens rod sleeve and is equipped with extension bar sealing and retainer ring, make to form sealing space in lengthening rod sleeve, retainer ring merges and can relatively rotate with extension bar matching, it lengthens rod sleeve one end and is connected to fixes sleeve, fixes sleeve is equipped with torque fitting, torque fitting connects with extension bar, lengthens rod sleeve vertical direction and is connected to control pressure line, shut-off valve and pressure gauge are housed on control pressure line.Pressure change in the utility model observable drill process in oil well pipe, and the pressure after the completion of punching in oil well pipe can be effectively controlled, to ensure construction safety.
Description
Technical field
The utility model is related to a kind of perforating device with pressure, especially suitable for oil field band pressure pipeline drilling operation with pressure.
Background technology
The old well head in oil field has some oil wells tube valve because corrosion or other reasons can not open at present, therefore, oil well
Residual pressure in pipe can not effective management and control, if directly replacing valve or well head, there are some potential safety problemss.Existing band
Pressure perforating device can not observe the pressure change in drill process in oil well pipe, also can not effectively control oil well pipe after the completion of punching
Interior pressure.
Invention content
The purpose of this utility model is to provide a kind of perforating device with pressure, the pressure in its observable drill process in oil well pipe
Power changes, and can also effectively control the pressure in oil well pipe after the completion of punching.
The utility model includes control valve, short circuit, drill bit, and lengthening rod sleeve is connected on control valve, lengthens in rod sleeve
There is an extension bar, connect with drill bit, lengthen rod sleeve and be equipped with extension bar sealing and retainer ring, make to form sealing in lengthening rod sleeve
Space, retainer ring merge and can relatively rotate with extension bar matching, lengthen rod sleeve one end and are connected to fixes sleeve, fixes sleeve is equipped with
Torque fitting, torque fitting connect with extension bar, lengthen rod sleeve vertical direction and are connected to control pressure line, are equipped with and cut on control pressure line
Only valve and pressure gauge.
Pressure change in the utility model observable drill process in oil well pipe can also effectively control oil after the completion of punching
Pressure in well casing, it is ensured that construction safety.
Description of the drawings
Fig. 1 is the utility model drilling pre-structure schematic diagram.
Fig. 2 is structure principle chart after the utility model drilling.
1- oil well pipes, 2- short circuits, 3- control valves, 4- drill bits, 5- shut-off valves, 6- pressure gauges, 7- control pressure lines, 8- are lengthened
Rod sleeve, 9- extension bars, the sealing of 10- extension bars, 11- retainer rings, 12- fixes sleeves, 13- torque fittings.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：The utility model includes control valve 3, short circuit 2, drill bit
4, it is connected on control valve 3 and lengthens rod sleeve 8, lengthening in rod sleeve 8 has an extension bar 9, connects with drill bit 4, lengthens rod sleeve 8
Equipped with extension bar sealing 10 and retainer ring 11, make to form sealing space in lengthening rod sleeve 8, retainer ring 11 matches with extension bar 9
Merging can relatively rotate, and lengthen rod sleeve 8 one and be terminated with fixes sleeve 12, fixes sleeve 12 is equipped with torque fitting 13, and torque connects
First 13 connect with extension bar 9, lengthen 8 vertical direction of rod sleeve and are connected to control pressure line 7, shut-off valve 5 and pressure are housed on control pressure line 7
Power table 6.
In use, short circuit 2 and 1 outer wall of oil well pipe are welded together, control valve 3 is opened, driving torque connector 13 passes through
Extension bar 9 drives drill bit 4 to punch oil well pipe 1, and when hole is got through, the oil-air pressure in oil well pipe 1 can be entered by control valve 3
Rod sleeve 8, control pressure line 7, shut-off valve 5, pressure gauge 6 are lengthened, extension bar sealing 10, extension bar are equipped with due to lengthening rod sleeve 8
Sleeve 8 is sealing space, when drill bit 4 drills through oil well pipe 1 with pressure, can determine that hole is by the pressure change of pressure gauge 6
It is no to get through, and gas or liquid spilling are not had, so that it is guaranteed that construction safety.After the completion of drilling, drill bit 4 is exited into control
Valve 3, and closing control valve 3 are emptied the pressure lengthened in rod sleeve 8 by shut-off valve 5, you can will lengthen rod sleeve 8 from control
It is dismantled at valve 3 processed, that is, completes drilling operation with pressure, since then, the pressure inside oil well pipe 1 can be controlled by control valve 3,
Ensure to carry out later replaces the safety of valve or replacement well head when operations.
