Problems solved by technology

However, the structure of the current petroleum screen is too simple. Generally, strip or hole-shaped screens are processed on the surface of the pipe, and some screens are made of stainless steel wire after drilling. Obviously, its filtering function is relatively poor. Poor, unable to filter in layers, unable to meet industrial needs; in addition, the current screen tube function is too single, can only perform screening operations, but cannot carry out normal transportation work, cannot meet people's needs, poor heat preservation effect, and is not durable Corrosion, short service life

Embodiment Construction

[0011] like figure 1 As shown, the double-pipe petroleum screen described in the embodiment of the present invention includes two filter inner cores 1 arranged side by side under the oil pipeline. The upper end of the filter inner core 1 is connected to a shunt pipe 8 led from the oil pipeline, and the lower ends of the two filter inner cores 1 are respectively connected to the collecting pipe 10 through a section of branch pipe. The collecting pipe 10 is vertically connected to a filter pipe 3, located A rotating filter ball 5 is installed inside through a rotating shaft 7, and a buckle cover 4 is provided at the outer end of each filter tube 3, and a mesh filter belt 6 is added in the lumen between the rotating filter ball 5 and the buckle cover 4, At the same time, the inside of the filter core 1 is sequentially provided with a first-stage filter screen 11 and a second-stage filter screen 12 from top to bottom, and the second-stage filter screen 12 is arranged at the center...

Abstract

The invention discloses a double-pipe petroleum screen comprising two inner filter cartridges below a petroleum pipeline. A distribution pipe led out from the petroleum pipeline is connected to the upper end of each inner filter cartridge. A collecting pipe is connected to the lower end\ of each inner filter cartridge through a branch pipe and is connected with a filter pipe. A rotary filter ball is mounted in each filter pipe through a rotary shaft. In addition, a primary filter mesh and a secondary filter mesh are sequentially disposed in each inner filter cartridge from top to bottom, while the secondary filter mesh is disposed in the center of the inner filter cartridge. The double-pipe petroleum screen has the advantages that distribution and screening prior to mix-filtering is achieved; the double-pipe petroleum screen is reasonable in structure, handy, practical, effective in filtering, and capable of filtering petroleum layer by layer and making usage convenient; during use, through the different filter structures, sand in petroleum can be filtered completely and functions of piping can be given to normal play.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, in particular to a double-pipe oil screen. Background technique [0002] At present, pipe fittings used in petroleum, chemical industry, electric power, shipbuilding, metallurgy, machinery, textile, food, construction, pharmaceutical and other industries need to have high strength, pressure resistance, corrosion resistance and high temperature resistance. Therefore, in petroleum In the field of mining technology, in order to improve the recovery rate of oilfield crude oil, secondary oil recovery and tertiary oil recovery are usually carried out. The screen pipe is installed at the bottom of the oil well to separate the extracted oil from the sand in the formation A special pipe. However, the structure of the current petroleum screen is too simple. Generally, strip or hole-shaped screens are processed on the surface of the pipe, and some screens are made of stainless steel wire after dri...
