Abstract
The utility model provides a kind of underground sand prevention device, and underground sand prevention device of the present utility model includes filter house, setting bar, end socket and installation portion.Filter house is the tubular structure of both ends insertion, and tubular structure has the gap for being used to filter sand grains being twist distributed vertically, and the width in gap is radially inwardly gradually reduced.Setting bar is axially fixed the medial surface in filter house.End socket is tightly connected located at one end of filter house and with filter house.Installation portion is located at the other end of filter house and is tightly connected with filter house.
Description
Technical field
Technical field of petroleum extraction is the utility model is related to, more particularly to a kind of underground sand prevention device.
Background technology
In oil-gas mining field, quartz sand is often got into by bottom using high pressure packing technology, with the shape around pit shaft
Into sand block barrier.In order to prevent the quartz sand of filling enters from entering flow controller with oil, gas, it is necessary to install underground in flow controller end
Sand control device.Existing underground sand prevention device has less mesh or gap, but easily occurs to block, it is necessary to frequently replacing or clear
Reason.
Utility model content
In view of this, the utility model provides a kind of underground sand prevention device, can prevent filter from being blocked by sand grains.
The utility model is solved the above problems by following technological means：
A kind of underground sand prevention device, including：
Filter house, the filter house are the tubular structure of both ends insertion, and the tubular structure has vertically twist
The gap for being used to filter sand grains of distribution, the width in the gap are gradually reduced radially inward；
Shape bar, is axially fixed in the medial surface of the filter house；
End socket, it is tightly connected located at one end of the filter house and with the filter house；
Installation portion, located at the filter house the other end and with the filter house be tightly connected.
Further, the tubular structure by a bonding jumper vertically spiral shell in capstan around being formed, the bonding jumper it is transversal
Face is taper.
Further, the setting bar has multiple, and bar is rounded is uniformly distributed for multiple setting；
Further, each setting bar welds with the bonding jumper.
Further, the end socket is hemispherical configuration, and the end socket welds with the filter house.
Further, the installation portion is loop configuration, and is welded with the filter house.
Further, the width in the gap is not more than 0.2mm.
Underground sand prevention device described in the utility model, due to the gap of filter house radial section width radially inwardly
It is gradually reduced；So that oil, gas, when having just enter into gap, the size in gap is smaller, may filter that drop grain, with oil, gas radially
Inwardly flowing, gap gradually broaden so that oil, flow of air are more smooth；And avoid sand grains from entering inside gap, prevent
Block.In addition, setting bar can be reinforced to filter house, it is unlikely to deform filter house.
Brief description of the drawings
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram of underground sand prevention device of the present utility model.
Fig. 2 is the enlarged drawing in A portions in Fig. 1.
Fig. 3 is the sectional view of the filter house of the underground sand prevention device in Fig. 1.
Fig. 4 is the enlarged drawing in B portions in Fig. 3.
Embodiment
In description of the present utility model, it is to be understood that term " " center ", " on ", " under ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, it is for only for ease of description the utility model and simplifies description, rather than indicates or imply and be signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
New limitation.In description of the present utility model, unless otherwise indicated, " multiple " are meant that two or more.
The utility model is described in detail below with reference to accompanying drawing, such as Fig. 1-Fig. 4, a kind of underground sand prevention device, including
Filter house 1, setting bar 2, end socket 3 and installation portion 4.
Filter house 1 is the tubular structure of both ends insertion, the tubular structure by a bonding jumper vertically spiral shell in capstan around being formed,
The cross section of the bonding jumper is taper.So that the tubular structure can have twist is distributed gap 11 vertically, gap 11
Width can be not more than 0.2mm, but not limited to this or other sizes, as long as sand grains can be filtered.The footpath in gap 11
It is taper to section, and the width in gap 11 is gradually reduced radially inward.Thus, prevent sand grains from entering the gap of filter house 1
11, avoid blocking, and ensure that filter house is usual.
Setting bar 2 can be string configuration, and its length can be equal to the axial length of filter house 1, and setting bar 2 can be vertically
The medial surface of filter house 1 is fixed on, and can be fixedly connected by modes such as welding with filter house 1.The quantity of setting bar 2 has more
It is individual, for example, 8,9 or 10 etc., do not do particular determination herein, and bar 2 is rounded is uniformly distributed in filter house 1 for multiple setting
Medial surface.
One end for being fixedly connected on filter house 1 that end socket 3 can be sealed by modes such as welding, and end socket 3 can be hemispherical
Structure.
Installation portion 4 can be located at the other end of filter house 1, and can be tightly connected by modes such as welding with filter house 1.Installation
Portion 4 can be loop configuration, and inner wall surface thereof can be provided with screw thread, to be connected with flow controller.
Other compositions on the underground sand prevention device described in the utility model embodiment etc. are those skilled in the art
Known to member, no longer describe in detail herein.
Finally illustrate, embodiment of above only to illustrate the technical solution of the utility model and unrestricted, although
The utility model is described in detail with reference to better embodiment, it will be understood by those within the art that, can be with
The technical solution of the utility model is modified or equivalent substitution, without departing from technical solutions of the utility model objective and
Scope, it all should cover among right of the present utility model.
