Description
Technical field
The utility model relates to oil field equipment fields, relate in particular to a kind of oil field well screen casing.
Background technique
In petroleum drilling and mining operation, oil field well screen casing is a kind of important equipment, frequently with earlier complete well or is recovered the oil anti-
Sand.The main function of oil field well screen casing is exactly sand control, the steel of screen casing used by geological environment difference locating for oil well causes
Grade is different with type.Existing oil field well screen casing is when suppressing the curved segment by high angle hole or horizontal well, inevitably
It to collide, compress and rub against with the borehole wall or casing, be easy to appear screen casing bending, cause screen damage or gap to deform, cause
Make to shine chiltern amount and sand controlling result reduces or failure.
Utility model content
The utility model passes through high angle hole suppressing mainly solving the technical problems that provide a kind of oil field well screen casing
Or horizontal well curved segment when, be unlikely to deform after colliding, compress and rub against with the borehole wall or casing, prevent sieve pore impaired as far as possible
It is bad, ensure sand controlling result.
To achieve the above objectives, the present invention provides the following technical solutions:
The oil field well screen casing includes circular tube shaped screen casing ontology open at one end, this body side surface of screen casing is uniformly provided with several thin
Long sieve pore, screen casing ontology closed end are equipped with hemispheric end cap, and screen casing body open end is connected with the cylindrical tubulose of spiral circle
Bourdon tube, spring tube end are communicated with screwed pipe, this body side surface of screen casing is symmetrically arranged with the protective plate of two arc plates, two protective plates
It is bent towards screen casing ontology, two protective plates pass through that several elastic elements are vertical with screen casing ontology to be connect.
As advanced optimizing for the technical program, the screen casing ontology, bourdon tube, screwed pipe by spring steel making,
Bourdon tube is connect by welding with screen casing ontology and screwed pipe.
As advanced optimizing for the technical program, the end cap and elastic element are manufactured by anti-corrosive rubber material,
End cap is connect by screw with screen casing ontology.
As advanced optimizing for the technical program, the protective plate passes through screw by spring steel making, elastic element
It is connect with screen casing ontology and protective plate.
Be using the beneficial effect of above technical scheme: the oil field well screen casing during installation can be by screwed pipe and oil
The oil pipe of field underground connects, and the oil well pump in the oil pipe of oil well is pumped through screen casing ontology, and petroleum is entered by sieve pore
Screen casing body interior can filter out sand.When the oil field well screen casing is suppressing the curved segment by high angle hole or horizontal well
When, after colliding, compress and rub against with the borehole wall or casing, flexible deformation can occur for bourdon tube, and two protective plates can also play
Protective action allows screen casing ontology to be unlikely to deform, and end cap can protect the end of screen casing ontology, prevents sieve pore impaired as far as possible
It is bad, ensure sand controlling result.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the main view of the utility model oil field well screen casing；
Fig. 2 is the top view of the utility model oil field well screen casing.
Wherein, 1- screen casing ontology, 2- bourdon tube, 3- screwed pipe, 4- end cap, 5- protective plate, 6- sieve pore, 7- elastic element.
Specific embodiment
The preferred embodiment of according to the present invention will be described in detail below with reference to the accompanying drawings oil field well screen casing.
Fig. 1 and Fig. 2 shows the specific embodiment of the utility model oil field well screen casing:
The oil field well screen casing includes circular tube shaped screen casing ontology 1 open at one end, 1 side of screen casing ontology combined with Figure 1 and Figure 2,
Face is uniformly provided with several elongated sieve pores 6, and 1 closed end of screen casing ontology is equipped with hemispheric end cap 4, and 1 open end of screen casing ontology connects
It is connected to the cylindrical sleeve pipe 2 of spiral circle, 2 end of bourdon tube is communicated with screwed pipe 3, and 1 side of screen casing ontology is symmetrically arranged with two
The protective plate 5 of arc plate, two protective plates 5 are bent towards screen casing ontology 1, two protective plates 5 by several elastic elements 7 with
Screen casing ontology 1 vertically connects.
Screen casing ontology 1, bourdon tube 2, screwed pipe 3 are by spring steel making, sturdy and durable and elastic good, bourdon tube 2
It is connect by welding with screen casing ontology 1 and screwed pipe 3.End cap 4 and elastic element 7 are manufactured by anti-corrosive rubber material, elasticity
Well, and corrosion resistance and good, it is suitble to work in oil field well, end cap 4 is connect by screw with screen casing ontology 1.Protective plate 5
It is sturdy and durable by spring steel making, and elasticity is good, and elastic element 7 is connected by screw and screen casing ontology 1 and protective plate 5
It connects.
The oil field well screen casing can be connect by screwed pipe 3 with the oil pipe of oil field well during installation, the oil pipe of oil well
Interior oil well pump is pumped through screen casing ontology 1, and petroleum is entered inside screen casing ontology 1 by sieve pore 6, can filter drop
Soil, then petroleum is entered in the pumping pipelines of oil well by screen casing ontology 1, bourdon tube 2, screwed pipe 3.When the oil field well screen casing
When suppressing the curved segment by high angle hole or horizontal well, after colliding, compress and rub against with the borehole wall or casing, bourdon tube 2
Flexible deformation can occur, and two protective plates 5 can also play protective action, and screen casing ontology 1 is allowed to be unlikely to deform, and end cap 4 can be protected
The end of screen casing ontology 1 has been protected, sieve pore 6 is prevented to be damaged as far as possible, has ensured sand controlling result.
The above are merely preferred embodiments of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this
The protection scope of utility model.
