Abstract
The utility model belongs to a product in oil industry, which is a special sand control tool used for drilling or well drilling system. The utility model is characterized in that: an upper end is connected with a sand control tool 1 and a light pipe A2, a tell-tale screen 3 and a light pipe B4, a lower end is connected with a fill tool 7, a conversion tool 6, a 3D screen 5, connection between the 3D screen 5 and the light pipe B4 and between parts adopts thread connection. The utility model has the advantages of reasonable structure and easy sand washing, thereby reducing breaking of fill gravel, reducing interference between procedures and shortening sand control well completion period.
Description
Technical field
The utility model belongs to the product of petroleum industry aspect, is the special-purpose sand preventing tool of probing or well system.
Background technology
In the petroleum industry field, existing situation is that sand control pipe often has sand preventing tool, crossover tool and packing tool to be combined into one, and then links together with light pipe, tell tale screen, three-dimensional screen casing etc.Or it is combined integrated with sand preventing tool and crossover tool, connect together with light pipe, tell tale screen, light pipe, three-dimensional screen casing, packing tool etc. again, perhaps link together by sand preventing tool, light pipe, tell tale screen, three-dimensional screen casing, packing tool etc., more than the connection of these several structures respectively have certain weak point, be not very scientifically to be assembled together, operation is many, and operation is trouble.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at prior art, and a kind of rational in infrastructure, easy to operate reverse sand control pipe is provided.
Its technical scheme is: the upper end is connected with light pipe A2, tell tale screen 3 and light pipe B4 by sand preventing tool 1, and the lower end is connected with crossover tool 6, three-dimensional screen casing 5 by packing tool 7, being connected all by the formation that is threaded between three-dimensional screen casing 5 and light pipe B4 and parts.The lower end of described packing tool 7 is processed as the scalene cone structure.
Effect of the present utility model is the fragmentation that structure is reasonable more, be convenient to sand washing, reduction pack gravel, has reduced the interference of inter process, has shortened the sand control completion cycle.
Description of drawings
As figure is structural principle schematic diagram of the present utility model.
Among the figure 1, sand preventing tool 2, light pipe A 3, tell tale screen 4, light pipe B 5, three-dimensional screen casing 6, crossover tool 7, packing tool
The specific embodiment:
As seen from the figure, its assembling order of connection is: the upper end is connected with light pipe A2, tell tale screen 3 and light pipe B4 by sand preventing tool 1, the lower end is connected with each crossover tool 6, three-dimensional screen casing 5 by packing tool 7, and being connected all between three-dimensional screen casing 5 and light pipe B4 and other parts forms by being threaded; The lower end of packing tool 7 is provided with the scalene cone structure, so that constructing operation.This syndeton form is different from order of connection structure in the past.
Claims (2)
1, reverse sand control pipe, it is characterized in that: the upper end is connected with light pipe A (2), tell tale screen (3) and light pipe B (4) by sand preventing tool (1), the lower end is connected with crossover tool (6), three-dimensional screen casing (5) by packing tool (7), being connected all by the formation that is threaded between three-dimensional screen casing (5) and light pipe B (4) and parts.
