Abstract
The utility model relates to a novel explosion shaper. The central position of the upper part of a joint is provided with a blind hole; a booster tube is arranged in the blind hole; the central position of the lower part of the joint is provided with a blind hole; a booster grain is arranged in the blind hole; the blind hole at the upper part and the blind hole at the lower part are coaxial; the blind hole at the upper part and the blind hole at the lower part are not communicated to guarantee the booster grain not to move upwards because of the action of underground high pressure. A main body grain is arranged in a guard shield and uses composite explosive using cyclotrimethylene trinitramine as a main body. The utility model has the advantages that no residue is reserved, well casing is not polluted, structure is simple, operation is convenient, and the novel explosion shaper is qucik and effective.
Description
The utility model relates to oilfield downhole casing and repairs: be specially adapted to oil (water) well gross distortion sleeve pipe.
Along with the prolongation of oil field development time, the sleeve pipe of oil well damages more and more serious, and the number of sleeve pipe fault well is also more and more, so the Casing Failure reparation has become important work in the oil field development.General casing swage adopts tube expander and roller reshaper more, and utilizing times hits the extruding force shaping sleeve pipe of power and rotation, and speed is slow, and the time is long, and running into complicated sleeve pipe deformation can't solve, and causes the down-hole lock of tool drilling sometimes.
The purpose of this utility model just provide a kind ofly do not pollute pit shaft, do not damage sleeve pipe, new use for explosive reshaper that shaping effect is good.
The purpose of this utility model is achieved in that a kind of new use for explosive reshaper, by connector, powder column, guard shield is formed, the central upper portion position of connector has blind hole, detonating primer is housed in the blind hole, the lower central position of connector has blind hole, booster gains is housed in the blind hole, upper blind bore is coaxial with the bottom blind hole, be not communicated with between upper blind bore and the bottom blind hole, the bottom surface of booster gains is connected with the main body powder column, the main body powder column is contained in the guard shield, and the bottom of connector is connected with the top seal of guard shield, and the top of connector is connected with priming device.
Characteristics of the present utility model:
1. can recover to be out of shape bigger oil (water) casing and use latus rectum.
2. can adjust main body powder column degree of packing flexibly so that the oil different to deflection (water) casing uses the new use for explosive reshaper of different charge density, guarantee not only to recover to use latus rectum but also do not damage sleeve pipe after the shaping.
3. do not stay any residue after the blast, do not pollute pit shaft.
4. simple in structure, easy to use, be easy to promote, fast effectively.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the central upper portion position of connector has blind hole 7, detonating primer 2 is housed in the blind hole 7, the lower central position of connector 1 has blind hole 6, booster gains 3 is housed in the blind hole 6, blind hole 6 is coaxial with blind hole 7, is not communicated with between blind hole 6 and the blind hole 7, guarantees that booster gains can not move up because of the down-hole high pressure effect.The bottom surface of booster gains 3 is connected with main body powder column 4, and main body powder column 4 is contained in the guard shield 5, and the main body powder column uses with the composite explosives of hexogen as main body.The bottom of connector 1 is connected with the top seal of guard shield 5, and the top of connector 1 is connected with priming device.Working programme is the primer detonator of the priming device detonating primer 2 that detonates, detonating primer 2 induced detonation booster gains 3, booster gains 3 is ignited main body powder column 4, and the energy that 4 blasts of main body powder column produce is delivered to distortion well section internal surface of sleeve pipe by liquid medium in the pit shaft and administers oil (water) well deformed casing.
