Abstract
The utility model discloses an oil well multistage filter which comprises an outer shell. Two filtering tubes are mounted on the outer side wall face of the outer shell, a rotating type filtering ball is mounted inside each filtering tube through a rotating shaft, a buckling cover is arranged at the outer end of each filtering tube, and a mesh type filter strip is additionally arranged inside a cavity between each rotating type filtering ball and each buckling cover. Meanwhile, a second stage filter screen is horizontally arranged at the center position inside the outer shell, a first stage filter screen is arranged in a filter inner cavity above the second stage filter screen, and the lower end of the outer shell is connected with an oil outlet tube and is provided with a valve. The oil well multistage filter has the advantages that a plurality of filtering structures, such as the filtering balls, the filter strips and the filter screens, are additionally arranged inside the filter inner cavity and the outer filtering tubes, and the oil well multistage filter has the advantages of being reasonable in structure, convenient and practical to use, strong in filtering effect, capable of filtering oil in a layering mode and providing convenient using conditions, and the like.
Description
Technical field
The utility model relates to technical field of petroleum extraction, relates in particular to a kind of oil well multistage filter.
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 oil well multistage filter 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 oil well multistage filter, comprise shell body, be positioned at two filter pipes are installed on the shell body outer side surface, be positioned at each filter pipe inside and by rotating shaft, a rotary filtering ball be installed, buckle closure is set and at rotary filtering ball mesh-type filter bag together with setting up in chamber between buckle closure in each filter pipe outer end, simultaneously, described shell body inside center position is horizontally disposed with second level screen pack one, the filtration inner chamber that is positioned at screen pack top, the second level is provided with first order screen pack, is positioned at shell body lower end connection flowline and configuration valve.
Seal closure is installed respectively in upper and lower two bottom surfaces of described shell body, on described shell body, observation port is set.
The beneficial effect of oil well multistage filter described in the utility model is: by setting up multiple filtration at filtration inner chamber, outer filter pipe, as filter ball, filter bag, screen pack, but possessed the advantages such as the strong layered filtration oil of rational in infrastructure, convenient and practical, filter effect, the service condition that facilitates; During use, by these different filtrations, after oil enters body, can enter filter element along the body surface and flow out again, can make the sandstone in fluid filter clean; In addition, the mouth place, the upper and lower end of filter pipe can realize the sealing operation to filter pipe, avoids liquid to flow out from filter pipe, makes the bring into normal play function of tubing of body.
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 oil well multistage filter of the utility model embodiment.
In figure: 1, shell body; 2, seal closure; 3, filter pipe; 4, buckle closure; 5, rotary filtering ball; 6, mesh-type filter bag; 7, rotating shaft; 8, filter inner chamber; 9, valve; 10, flowline; 11, first order screen pack; 12, second level screen pack; 13, observation port.
The specific embodiment
As shown in Figure 1, the described oil well multistage filter of the utility model embodiment, comprise shell body 1, seal closure 2 and shell body 1 upper end connection oil inlet pipe are installed respectively in upper and lower two bottom surfaces of described shell body 1, be positioned at and offer two filter pipes 3 on shell body 1 outer side surface, the filter pipe 3 of each is respectively perpendicular to shell body 1 side wall surface; Be positioned at each 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 cavity between buckle closure 4 in each filter pipe 3 outer ends, simultaneously, described shell body 1 inside center position is horizontally disposed with second level screen pack 12 one, the filtration inner chamber 8 that is positioned at second level screen pack 12 tops is provided with first order screen pack 11, and the shell body 1 of every one-level screen pack position arranges respectively an observation port 13; In addition, be positioned at shell body 1 lower end connection flowline 10 and configuration valve 9.
