Abstract
The utility model relates to a strong sand washing device, which comprises an upper joint 1, a jacket 3, a telescopic pipe 4, and a blocking ring 5. The upper joint is connected to the upper end of the jacket, and the blocking ring is connected to the lower end of the jacket. The telescopic pipe is installed on an inner hole of the blocking ring, the exterior of the upper end of the telescopic pipe is provided with a connecting ring 2 which is positioned in and inner hole of the jacket and can slide between the lower end of the upper joint and the upper end of the blocking ring. The telescopic pipe can drop down together with a sand surface under the action of hydraulic force, a pipe column does not need to be moved on a well head, and thus, continuous and quick sand washing is realized, the utility model has the advantages of simple structure, and flexible operation.
Description
The utility model belongs to the down-hole sand flushing tool that uses on a kind of oilfield.
Sand flushing tool commonly used at present is the sand washing nib, use this instrument sand washing, when the sand face reduces, the hydraulic blow distance that can not remain valid to the sand face of sand washing nozzle then, so just need move down tubing string at well head, do like this and can cause sand washing efficient low, working strength of workers is big, poor working environment.ZL96228320 provides a kind of " telescopic continuous sand flushing device ", but it exists complex structure, the relatively poor shortcoming of operating flexibility.
The purpose of this utility model is a kind of Strong sand washing device of design, and it should be able to be realized continuously, sand washing fast, and should have characteristics simple in structure, flexible operation.
The utility model includes top connection 1, overcoat 3, telescoping tube 4, catch ring 5, top connection 1 is connected the upper end of overcoat 3, catch ring 5 is connected the lower end of overcoat 3, telescoping tube 4 is installed in the endoporus of catch ring 5, outside, telescoping tube 4 upper end is provided with connecting ring 2, connecting ring 2 is arranged in overcoat 3 endoporus, and can slide between the upper end of the lower end of top connection 1 and catch ring 5.
The utility model can be connected below the tubing string (or drill string) and G.I.H when concrete work, arrives the sand face, and well head connects hose, pumps into sand cleaning fluid, and sand cleaning fluid is from telescoping tube 4 ejections.Along with sand is flushed away, the sand face descends, and telescoping tube 4 stretches out under the effect of fluid power automatically, contact sand face, thus the hydraulic blow distance that water spout is remained valid to the sand face all the time, need not be at the moving again tubing string of well head.Realize sand washing fast continuously automatically thus.It also has advantage simple in structure, flexible operation.
Fig. 1 is an internal construction schematic diagram of the present utility model, and Fig. 2 is the structural representation of embodiment two.
Embodiment one: present embodiment is made up of top connection 1, overcoat 3, telescoping tube 4, catch ring 5, the external screw thread 1-1 of top connection 1 lower end is connected with the internal thread 3-1 spiral of overcoat 3 upper ends, and the external screw thread 5-1 of catch ring 5 upper ends is connected with the internal thread 3-2 spiral of overcoat 3 lower ends.Telescoping tube 4 is installed in the catch ring 5, and connecting ring 2 is installed in the endoporus of telescoping tube 4 between top connection 1 and catch ring 5, and the external screw thread 4-1 spiral of the internal thread 2-1 of connecting ring 2 and telescoping tube 4 upper ends is connected.
Embodiment two: present embodiment and embodiment one are different is connecting ring 2 and telescoping tube 4 is linked to be T shape pipe 6 for one.Other composition is identical with embodiment one with annexation.
