Abstract
Disclosed is a built-in sand-proof pipe which belongs to the machinery products of oil drilling in oil industry, mainly to improve the sand-proof effect. The utility model is characterized in that a base pipe is arranged outside the sand-proof pipe. An upper joint (1) is connected with a base pipe (4); a sealed body (3) positioning matches with the upper joint (1) through a bush (2); a sand-proof pipe (5) is connected with a lower joint (6) that is connected with the base pipe (4). The beneficial effects are that the utility model is simple in structure and good in sand-proof effect.
Description
One, technical field
The utility model belongs to the engineering goods of the mud oil of petroleum industry system.
Two, background technology
In the past, parent tube is in the inside of anti-sandpipe, and an end of anti-sandpipe is connected with parent tube by shear pin, and the other end adopts to weld and links to each other with parent tube, and the pin end seals therebetween gap with sealed stuffing box.This form of structure often influences sand controlling result.
Three, summary of the invention
The purpose of this utility model provides built-in anti-sandpipe.Solve parent tube and be placed in the outside of preventing sandpipe, improve sand controlling result.It mainly is made of top connection, parent tube, anti-sandpipe and lower contact etc.
The beneficial effects of the utility model be simple in structure, sand controlling result good.
Four, description of drawings
As figure is structural principle schematic diagram of the present utility model.
Among the figure 1, top connection, 2, lining, 3, seal, 4, parent tube, 5, anti-sandpipe, 6, lower contact,
Five, by way of example
As seen from the figure, parent tube 4 is installed in the outside of anti-sandpipe 5, and wherein top connection 1 is connected with parent tube 4, and it is supporting that seal 3 relies on linings 2 and top connection 1 to locate, and prevents that sandpipe 5 is connected with lower contact 6, lower contact 6 formation that links to each other with parent tube 4.
