Description

Self-cleaning oil-sand eliminator
Technical field
The utility model belongs to oil-sand separation technology field in the oil exploitation, especially relates to a kind of self-cleaning oil-sand eliminator.
Background technology
At present; Though domestic have a variety of for the machinery oil sand separator in the oil exploitation; But what practical application was more is boring oil pipe outer casing stainless steel screen separators or stainless steel wire wound web oil-sand eliminator, though these oil-sand eliminator strainabilities are good, corrosion-resistant; But, but can't overcome mesh by the generation of grit clogging.Grit stops up the oil field oil production is descended, but also can cause oil pumper to increase power consumption because of oil-pumping resistance strengthens, and shortens the application life of oil-sand eliminator greatly.Because the oil-sand eliminator is the indispensable product of every mouthful of producing well, oil-sand eliminator requirement is very big, so the also corresponding raising of cost for oil production.
Summary of the invention
It is high that the purpose of the utility model provides a kind of sand control efficient, long service life, and rely on self design feature filter screen to be carried out the oil-sand eliminator of automated cleaning.
The purpose of the utility model realizes through following technical proposals:
A kind of self-cleaning oil-sand eliminator of the utility model; It is characterized in that being evenly equipped with the outer pillar of through hole by the surface; The interior sand screen that is connected through pair of bearings with pillar in addition, therewith in a pair of rotating vane that is fixedly connected of sand screen inwall two ends, be located at one group of cleaning brush of said outer pillar inwall one side; Be located at the spring top clamping device between said outer pillar and the said cleaning brush; Form with the petroleum pipeline joint that weld mutually at said outer pillar two ends, described outer pillar inwall one side is provided with axial mounting groove, is provided with described spring top clamping device in the described axial mounting groove; Described one group of cleaning brush is plugged on successively in the described axial mounting groove and with described spring top clamping device and is abutted against mutually, and described interior sand screen tube wall surface evenly is covered with micro through-hole;
Described petroleum pipeline joint is a nipple;
The diameter of described micro through-hole is the 0.07-0.4 millimeter.
The advantage of the utility model:
1) rely on the design feature of self can realize that just oil-sand separates, and has self-cleaning function.Because the utility model pillar inwall outside is provided with one group of cleaning brush, and the rotation through interior sand screen makes outer pillar and interior sand screen formation relative motion, the cleaning of grit on the internal sand screen tube wall of realization cleaning brush.
2) since the self-cleaning cleaning system of the utility model to be arranged on the oil-sand eliminator inner, do not take up room, do not receive the narrow and small restriction of working environment.
3) flow into the crude oil in the oil-sand eliminator because the rotation of the interior sand screen of the utility model is dependence, the rotating vane that promotes to be connected on the interior sand screen inwall drives interior sand screen rotation, does not need the external application power source, just can realize automated cleaning.
4) produce the not underproduction in oil recovery, do not prolonged application life of oil-sand eliminator when increasing consumption greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A sectional view of the utility model Fig. 1.
The specific embodiment
Further specify the specific embodiment of the utility model below in conjunction with accompanying drawing.
Like Fig. 1, shown in 2; A kind of self-cleaning oil-sand eliminator is characterized in that being evenly equipped with by the surface the outer pillar 2 of through hole 6, the interior sand screen 8 that is connected through pair of bearings 3 with pillar 2 in addition; The a pair of rotating vane 4 that interior therewith sand screen 8 inwall two ends are fixedly connected; Be located at one group of cleaning brush 7 of said outer pillar 2 inwalls one side, be located at the spring top clamping device 5 between said outer pillar 2 and the said cleaning brush 7,1 composition of petroleum pipeline joint that welds mutually with said outer pillar 2 two ends; Described outer pillar 2 inwalls one side is provided with axial mounting groove; Be provided with described spring top clamping device 5 in the described axial mounting groove, described one group of cleaning brush 7 is plugged on successively in the described axial mounting groove and with described spring top clamping device 5 and is abutted against mutually, and described interior sand screen 8 tube wall surfaces evenly are covered with micro through-hole.
Described petroleum pipeline joint 1 is a nipple.
The diameter of described micro through-hole is the 0.07-0.4 millimeter.
The self-cleaning oil-sand eliminator of the utility model is connected with petroleum pipeline through described petroleum pipeline joint 1, is installed in the bottom of oil well pump.When oil well pump moves upward; Negative pressure is formed on the oil well pump bottom; At this moment crude oil flows in the eliminator through the through hole on the outer pillar 26, promotes rotating vane 4 and drives interior sand screen 8 rotations, at this moment; Interior sand screen 8 forms relative motion with outer pillar 2, is connected cleaning brush 7 removings on outer pillar 2 inwalls attached to the gravel on interior sand screen 8 outer walls.When crude oil when oil well pump moves downward has partial reflux, crude oil can promote rotating vane 4 and drive in sand screen 8 reverse rotations, same, remove attached to the brush 7 that is cleaned of the gravel on interior sand screen 8 outer walls.Action of sand removal repeatedly through such realizes fine sand, flour sand, silt particle in the crude oil are separated from crude oil.Crude oil after this self-cleaning oil-sand eliminator filters flows into oil pipe again.The design feature of self that relies on the utility model can realize that just oil-sand separates, and has self-cleaning function; Because the utility model pillar 2 inwalls outside is provided with one group of cleaning brush 7, and the rotation through interior sand screen 8 makes outer pillar 2 and interior sand screen 8 form relative motions, the cleaning of grit on the sand screen tube wall in 7 pairs of the realization cleaning brush; In addition, it is inner that the self-cleaning cleaning system of the utility model is arranged on the oil-sand eliminator, do not take up room, and do not receive the narrow and small restriction of working environment; Moreover the rotation of sand screen 8 is to rely on the crude oil that flows in the oil-sand eliminator in the utility model, and sand screen 8 rotations in the rotating vane 4 in promoting to be connected on sand screen 8 inwalls drives do not need the external application power source, just can realize automated cleaning.The utility model is produced the not underproduction in oil recovery, has not been prolonged the application life of oil-sand eliminator when increasing consumption greatly.
