CN203271689U - Double-barreled type petroleum screen pipe - Google Patents

Abstract

The utility model discloses a double-barreled type petroleum screen pipe which comprises two filter inner cores on the lower portion of a petroleum pipeline. A flow divider pipe led out from the petroleum pipeline is connected at the upper end of each filter inner core, the lower ends of the two filter inner cores are connected with flow collecting pipes through branch pipes respectively, the flow collecting pipes are perpendicularly connected with a filter pipe, a rotary type filter ball is arranged inside the filter pipe through a rotary shaft, a first level filter screen and a second level filter screen are arranged inside each filter inner core from top to bottom in sequence, and each second filter screen is arranged at the central position of each filter inner core. The double-barreled type petroleum screen pipe has the advantages that the purpose that flow dividing and screening are carried out first and then mixing and filter are carried out is achieved, and the double-barreled type petroleum screen pipe is reasonable in structure, convenient to use, practical, strong in filter effect, capable of filtering petroleum in layers and providing convenient using conditions and the like. When the double-barreled type petroleum screen is used, through the different filter structures, sand and stone in the liquid petroleum can be filtered thoroughly, and the function of ordinary tubular products can further be performed.

Description

A kind of double hose Petroleum screen tube

Technical field

The utility model relates to technical field of petroleum extraction, relates in particular to a kind of double hose Petroleum screen tube.

Background technology

At present, the pipe fitting that is applied to the industries such as oil, chemical industry, electric power, boats and ships, metallurgy, machinery, weaving, food, building, pharmacy all needs to possess higher intensity, resistance to pressure, corrosion-resistant, resistance to elevated temperatures, therefore, in technical field of petroleum extraction, in order to improve the recovery ratio of crude oil, usually will carry out secondary oil recovery and tertiary oil recovery, screen casing is installed on oil well bottom, a kind of special tubes that the oil that is used for exploiting out separates with the sandstone on stratum.But present Petroleum screen tube structure is too simple, generally at tubing table wall processing strip or poroid screen casing, also some screen casing is to adopt stainless steel wire to be wound around after punching to make screen casing, and clearly, its filtering function is relatively poor, can't layering filter, can not satisfy industrial requirement; In addition, present screen casing function is too single, can only carry out the sieving operation, but can't carry out normal transportation work, can't satisfy people's demand, and heat insulation effect is not good enough, not corrosion-resistant, application life is short.Therefore, for above aspect, need to make rational improvement.

The utility model content

But the purpose of this utility model is to provide the double hose Petroleum screen tube of the strong layered filtration oil of a kind of rational in infrastructure, convenient and practical, filter effect, the service condition that facilitates, to solve many deficiencies of prior art.

The purpose of this utility model is come specific implementation by the following technical programs:

A kind of double hose Petroleum screen tube, two filtration inner cores that comprise the petroleum pipeline below, each filters isocon of being drawn by petroleum pipeline of inner core upper end connection, being positioned at two filters the inner core lower end and connects header by one section arm separately, filter pipe of the vertical connection of this header, be positioned at filter pipe inside and by rotating shaft, a rotary filtering ball be installed, simultaneously, in described filtration, core inner sets gradually first order screen pack, second level screen pack and second level screen pack from top to bottom and is arranged on the center position that filters inner core.

Seal closure is installed respectively in upper and lower two bottom surfaces of described filtration inner core, buckle closure is set and at rotary filtering ball mesh-type filter bag together with setting up in tube chamber between buckle closure in each filter pipe outer end.

The beneficial effect of double hose Petroleum screen tube described in the utility model is: filter inner core by double hose is set, and connect simultaneously a filter pipe at two inner core ends, realized that first shunting screens the purpose of hybrid filtering again, but possessed the advantages such as rational in infrastructure, convenient and practical, the strong layered filtration oil of filter effect, the service condition that facilitates; During use, by these different filtrations, the sandstone in fluid is filtered totally, the function of the tubing of also can bringing into normal play.

Description of drawings

The below is described in further detail the utility model according to drawings and embodiments.

Fig. 1 is the structure chart of the described double hose Petroleum screen tube of the utility model embodiment.

In figure: 1, filter inner core; 2, seal closure; 3, filter pipe; 4, buckle closure; 5, rotary filtering ball; 6, mesh-type filter bag; 7, rotating shaft; 8, isocon; 9, valve; 10, header; 11, first order screen pack; 12, second level screen pack.

The specific embodiment

as shown in Figure 1, the described double hose Petroleum screen tube of the utility model embodiment, comprise two filtration inner cores 1 that are listed in petroleum pipeline below setting, on described filtration inner core 1, seal closure 2 is installed respectively in lower two bottom surfaces and each filters isocon 8 of being drawn by petroleum pipeline of inner core 1 upper end connection, being positioned at two filters inner core 1 lower end and connects header 10 by one section arm separately, filter pipe 3 of these header 10 vertical connections, be positioned at filter pipe 3 inner by rotary filtering ball 5 of rotating shaft 7 installations, buckle closure 4 is set and at rotary filtering ball 5 mesh-type filter bag 6 together with setting up in tube chamber between buckle closure 4 in each filter pipe 3 outer ends, simultaneously, described filtration inner core 1 inside sets gradually first order screen pack 11 from top to bottom, second level screen pack 12 and second level screen pack 12 are arranged on the center position that filters inner core 1, in addition, be positioned at configuration valve 9 on the pipeline section that filters inner core 1 lower end.

Claims (3)

1. double hose Petroleum screen tube comprises that two of petroleum pipeline below filter inner cores, it is characterized in that:

Each filters isocon of being drawn by petroleum pipeline of inner core upper end connection, being positioned at two filters the inner core lower end and connects header by one section arm separately, filter pipe of the vertical connection of this header, be positioned at filter pipe inside and by rotating shaft, a rotary filtering ball be installed, simultaneously, in described filtration, core inner sets gradually first order screen pack, second level screen pack and second level screen pack from top to bottom and is arranged on the center position that filters inner core.

2. a kind of double hose Petroleum screen tube as claimed in claim 1 is characterized in that: seal closure is installed respectively in described filtration inner core upper and lower two bottom surfaces.
