Description
Technical field
It is especially a kind of novel actively to catch sandpipe the utility model relates to oil exploitation device.
Background technique
Currently, for nonflowing well, crude oil is taken out from oil well generally by the way of pumping during oil extraction
It send to ground.Due to the loose cementation of oil reservoirs or fluid scouring etc., during oil extraction, easily there is silt particle
It migrates and comes out from oil reservoirs with crude oil, and be blended in the situation in crude oil.In order to reduce erosion or stratum of the reservoir sand to pump
Sand holddown, thus it is existing the most commonly used is below the oil inlet of pump install additional cutting seam sieve tube or winding package fibre sand prevention pipe prevented
Sand causes pump efficiency to decline, cannot reach steady production since existing sand-proof pipe can generate different degrees of blocking at any time
Purpose；Reservoir sand is blocked in outside sand-proof pipe and is deposited to shaft bottom again, easily buries payzone, influences oil well production, shortens the well workover period.
Utility model content
The utility model mainly overcomes shortcoming in the prior art, proposes a kind of will not block and that pump efficiency is high is new
Type actively catches sandpipe.
The utility model solves technical solution provided by above-mentioned technical problem: it is a kind of it is novel actively catch sandpipe, including
Outer tube, inner tube, lower contact, pod, said inner tube upper end are sealed end, and lower end is open end, and lower end is mounted on lower contact
Interior, the lower contact is mounted in outer tube lower end inner wall, and the outer tube, inner tube coaxial arrangement, the pod are mounted on inner tube
Upper end, said inner tube upper end are radially provided with sieve pore, and the sieve pore is located in pod.
Further, the pod lower end is equipped with connection plate muscle, sand block annulus, the connection are equipped in the outer tube
Plate muscle one end is connected to the lower end outer wall of pod, and the other end is connected on the inner wall of sand block annulus.
Further, the number of the connection plate muscle is three, and it is evenly arranged on the inner wall of sand block annulus.
Further, the pod inner wall is equipped with spiral shape protrusion.
Further, said inner tube lower thread is connected in lower contact, the lower contact is threaded under outer tube
It holds in inner wall.
The beneficial effects of the utility model are: 1, avoid blocking fluid course, 2, improve pump efficiency, 3, extend pump use the longevity
Life, 4, avoid sand setting cover oil reservoirs, extend the well workover period.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that plate muscle, the attachment structure schematic diagram of sand block annulus, pod are connected in the present embodiment.
It is as shown in the figure: 1- outer tube, 2- inner tube, 3- lower contact, 4- connection plate muscle, 5- sand block annulus, 6- pod, 7- spiral
Shape protrusion, 8- sieve pore.
Specific embodiment
Further description is done to the utility model below with reference to embodiment and attached drawing.
As shown in Figure 1, a kind of of the utility model novel actively catches sandpipe, including outer tube 1, inner tube 2, lower contact 3, water conservancy diversion
Cover 6,2 upper end of said inner tube are sealed end, and lower end is open end, and lower end is mounted in lower contact 3, the cavity with lower contact 3
Connection, the lower contact 3 are mounted in 1 lower end inner wall of outer tube, and the outer tube 1, inner tube 2 are coaxially disposed, and the pod 6 is installed
In 2 upper end of inner tube, 2 upper end of said inner tube is radially provided with sieve pore 8, and the sieve pore 8 is located in pod 6.In its 1 upper end of middle external tube
Equipped with top connection screw thread, convenient for series connection.
As shown in Fig. 2, preferred embodiment is the water conservancy diversion in order to further increase sand block effect in the present embodiment
It covers 6 lower ends and is equipped with connection plate muscle 4, be equipped with sand block annulus 5 in the outer tube 1, described 4 one end of connection plate muscle is connected to pod 6
Lower end outer wall, the other end is connected on the inner wall of sand block annulus 5.
The utility model is in practical application, the utility model is mounted on the oil inlet of pump or is arranged in pump lower part
Casing in, the crude oil with sand is drawn into inner tube 2, is then entered in pod 6 by sieve pore 8, because of the resistance of pod 6
It keeps off, in the cavity turned back between outer tube 1, inner tube 2 with sandy plain oil, because the density of sand is larger, sand is separated with crude oil and deposited to
In the cavity between outer tube 1, inner tube 2 in lower contact 3, crude oil is using the gap between sand block annulus 5, pod 6 to pump
It is interior, complete sand control process.
Its for better sand control, can in practical application, the sandpipe of actively catching of the utility model is carried out multiple series connection,
It is that second lower contact 3 for actively catching sandpipe is threaded in 1 upper end of outer tube that first is actively caught sandpipe, to carry out
Multiple sand controls improve sand control efficiency.
In embodiment, sand block annulus 5 connects pod 6 by connection plate muscle 4, and connection plate muscle 4 plays connection support
Effect, therefore in order to improve the support force of connection plate muscle 4, preferred embodiment is that the number of the connection plate muscle 4 is three
It is a, and be evenly arranged on the inner wall of sand block annulus 5.
Its band sandy plain oil turns back in pod 6 and completes sand, crude oil separation, for point for further improving sand, crude oil
From effect, accordingly, it is preferred that embodiment is, 6 inner wall of pod is equipped with spiral shape protrusion 7.This belt transect sandy plain oil is being led
The sand in crude oil is thrown to by 1 inner wall of outer tube by spiral rotating when turning back in stream cover 6, is deposited on connector 3, outer tube 1, between inner tube 2
Cavity in, to improve separating effect.Sand is deposited on connector 3, outer tube 1, in the cavity between inner tube 2 simultaneously, rather than weight
Shaft bottom newly is deposited to, so that the sand for reducing well buries degree, extends the production cycle of well.
It is deposited on connector 3, outer tube 1, the sand in the cavity between inner tube 2, acts pit shaft with catching sandpipe when workover treatment.For
It is convenient to clean connector 3, outer tube 1, accumulates sand setting in the cavity between inner tube 2, preferred embodiment is, under said inner tube 2
End is threaded in lower contact 3, and the lower contact 3 is threaded in 1 lower end inner wall of outer tube.
The above does not impose any limitation on the present invention, although the utility model passed through it is above-mentioned
Embodiment discloses, however is not intended to limit the utility model, any person skilled in the art, practical not departing from
In new technique aspects, is made when the technology contents using the disclosure above and change or be modified to a bit the equivalent of equivalent variations
