Abstract
The utility model relates to a well washing device used for oil fields, in particular to a continuous sand-washing device for horizontal wells. The technical scheme is as follows: the continuous sand-washing device comprises a joint, a sand-washing swirl centralizer and a nozzle; the sand-washing swirl centralizer has a hollow tubular structure; one end of the sand-washing swirl centralizer is provided with a joint and the other end thereof is internally provided with the nozzle; and a pin is arranged at the nozzle of the sand-washing swirl centralizer. The continuous sand-washing device has the advantages of simple structure, convenience in use, low cost and free of danger, and can realize the aim of continuously washing sands during the well washing process.
Description
One, technical field
The utility model relates to the well washing apparatus that a kind of oil field is used, and is a kind of horizontal well continuous sand flushing device concretely.
Two, background technology
At present, along with improving constantly of oil field development level, directed horizontal well is more and more.The horizontal well problem of shaking out is more and more serious, the sand in the well can't be gone out fully by former sand washing means at all, causes precipitation card tubing string easily, makes troubles to job execution.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of simple in structure, with low cost, do not have a dangerous horizontal well continuous sand flushing device.
Its technical scheme is: it comprises joint, sand washing eddy flow centralizer and nozzle, and sand washing eddy flow centralizer is a hollow tubular structure, and the one end is provided with joint, and other end inside is provided with nozzle, and the nozzle place of sand washing eddy flow centralizer also is provided with pin.
The utlity model has simple in structure, easy to use, with low cost, do not have dangerous advantage, and the purpose of continuous sand flushing can realize well-flushing the time.
Four, description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Five, the specific embodiment
As shown in the figure, a kind of horizontal well continuous sand flushing device comprises joint 1, sand washing eddy flow centralizer 4 and nozzle 2, sand washing eddy flow centralizer 4 is a hollow tubular structure, the one end is provided with joint 1, and other end inside is provided with nozzle 2, and nozzle 2 places of sand washing eddy flow centralizer 4 also are provided with pin 3.
In the use, the cementing truck pipeline is received on the joint 1, and water is squeezed in the well through oil pipe by sand washing eddy flow centralizer 4, realizes the purpose of continuous sand flushing, and the eddy flow of sand washing simultaneously centralizer 4 has played the effect of eddy flow supercharging, makes the continuous sand flushing better effects if.
