Abstract
The utility model relates to an explosion shaper. A hose filled up with dynamite is wound on a center pole; a guard casing is arranged outside of the hose; one end of the center pole is screwed with a guide head, and the other end is connected with a detonator; the charging density of a pellet can be flexibly regulated in order to use the explosion shaper with different charging density to oil (water) casing tubes with different deformation to guarantee that diameters are desterilized and the casing tubes are not damaged after shape; the utility model has the advantages of no pollution to a well casing after explosion, simple structure, convenient operation, high speed and efficiency.
Description
The utility model relates to oilfield downhole casing and repairs; Be specially adapted to oil (water) well deformed casing.
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, and therefore the reparation of oil (water) casing 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, explosive shaping device that shaping effect is good.
The purpose of this utility model is achieved in that a kind of explosive shaping device, form by center-pole, powder column, guard shield, guide head, the center-pole two ends have screw thread, explosive is packed in the flexible pipe, the flexible pipe of filling explosive is wrapped on the center-pole, guard shield is located at the flexible pipe outside, and an end of center-pole is threaded with guide head, and the other end is connected with priming device.
Be axially arranged with four blades on the guide head, angle is 90 degree between the adjacent blades, and the first end that leads is provided with internal thread, and the other end is a hemispherical.
Characteristics of the present utility model: 1, can adjust the powder column degree of packing flexibly,, guarantee not only to recover to use latus rectum but also do not damage sleeve pipe after the shaping so that the oil different to deflection (water) sleeve pipe uses the explosive shaping device of different charge density.
2, do not pollute pit shaft after the blast.
3, 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, center-pole 1 two ends have screw thread, and center-pole 1 usefulness φ 16 round steel are made, and explosive is packed in the flexible pipe 2, and explosive is to make based on the composite explosives of hexogen.The flexible pipe 2 of filling explosive is wrapped on the center-pole 1, and guard shield 3 is located at flexible pipe 2 outsides, and the wear-resisting dry goods material of guard shield 3 usefulness is made, as cotton.One end of center-pole 1 is threaded with guide head 4, and the other end is connected with priming device.Axial direction is provided with four blades on the guide head 4, and angle is 90 degree between the adjacent blades, and guide head 4 one ends are provided with internal thread, and the other end is a hemispherical.
Working programme is primer detonator flexible pipe 2 explosives that detonate, and the energy that explosive charge produces is delivered to distortion well section internal surface of sleeve pipe by the liquid medium in the pit shaft and administers oil (water) well deformed casing.
