Description
Technical field
The utility model belongs to the oil drainage technology field of oil extraction in oil field underground tubing string, and in particular to a kind of waterpower pressure transmitting type
Bleeder.
Background technology
At present, oil field is widely popularized the hammering oil discharger used, between deep well pump and standing valve assembly, though
Right technology is ripe, but there are application limitation.Hammering oil discharger will be unable to open in a case where, such as：A. holddown,
B. rod parting, c. pistons break, and de-, d. pit shafts are unclean, e. is influenced by hole deviation, and impact force is inadequate under shock rod, it is impossible to hits
Disconnected draining pin.
Due to the abnormal conditions that current hammering oil discharger occurs in application process, causing bleeder can not normally open
Draining, when whole oil well pipe rises, crude oil in oil pipe is also brought to wellhead ground, can cause the pollution of well head environment.
Utility model content
In order to overcome the shortcomings of that existing hammering oil discharger can not open draining, technology to be solved in the utility model
Problem is to provide a kind of waterpower pressure transmitting type bleeder simple in structure, repair and replacement are convenient, the course of work is safely controllable.
In order to solve the above technical problems, the technical solution of the utility model is：Waterpower pressure transmitting type bleeder, is installed on oil recovery
Between tubing string and oil well pump, including draining valve body, the upper end of the draining valve body are connected with flow string, the draining valve body
Lower end be connected with oil well pump；The outer surface of the draining valve body is machined with the oil leak hole of connection valve chamber, in the oil leak hole
Seal washer is provided with, positive arch rupture disk, the positive arch rupture disk and the draining are provided with the outside of the seal washer
The pressing device for compressing the positive arch rupture disk is provided between hole.
As preferable technical solution, the pressing device include being arranged at connection screw thread on the oil leak hole hole wall with
And the clamp nut being connected through a screw thread with the oil leak hole.
As preferable technical solution, the oil leak hole is set along the radial disbalance or non-eccentricity of draining valve body.
As preferable technical solution, the positive arch rupture disk is pressure blasting type right arch notch type rupture disk.
By adopting the above-described technical solution, the utility model has the advantages that：
(1) simple in structure, manufacture is easy to maintenance, of low cost；Positive arch rupture disk is only needed to change after each use, is passed through
Can go into the well reuse again after pressure testing qualification；
(2) positive arch rupture disk can be directed to transmit water body pressure, and when bearing pressure and exceeding setting pressure, and rupture disk will be to
Outer side positioning is opened, and without fragment during explosion, reaction speed is fast, beneficial to quick draining, shortens well workover and accounts for the well time, improves oil well profit
Used time rate.
(3) for pit shaft it is dirty, be easy to precipitate the dirty well for blocking pump barrel, its using effect is unaffected；It is dirty to reduce well head
The yield of water, greasy filth, safety and environmental protection are controllable.
Brief description of the drawings
The following drawings is only intended in doing schematic illustration and explanation to the utility model, does not limit the model of the utility model
Enclose.Wherein：
Fig. 1 is the structure diagram of the utility model embodiment；
Fig. 2 is the partial enlarged view at I in Fig. 1；
Fig. 3 is the structure diagram of positive arch rupture disk.
In figure：1- draining valve bodies；2- seal washers；The positive arch rupture disks of 3-；4- clamp nuts.
Embodiment
Below in conjunction with the accompanying drawings and example, the utility model is expanded on further.In the following detailed description, explanation is only passed through
Mode describe some one exemplary embodiments of the utility model.Undoubtedly, those of ordinary skill in the art can recognize
Know, can be with a variety of modes to described reality in the case of the spirit and scope without departing from the utility model
Example is applied to be modified.Therefore, attached drawing and description are regarded as illustrative in nature, rather than for limiting the protection model of claim
Enclose.
As depicted in figs. 1 and 2, waterpower pressure transmitting type bleeder, including draining valve body 1, the outer surface of the draining valve body 1 add
Work has the oil leak hole of connection valve chamber, seal washer 2 is provided with the oil leak hole, 2 material of seal washer uses red copper, overall close
It is good to seal effect；The outside of the seal washer 2 is provided with positive arch rupture disk 3, the positive arch rupture disk 3 and the oil leak hole it
Between be provided with the pressing device for compressing the positive arch rupture disk 3.In the present embodiment, the pressing device includes being arranged at described
Connection screw thread on oil leak hole hole wall and the clamp nut 4 being connected through a screw thread with the oil leak hole, by clamp nut not
Only it is easy to the replacement and assembling of positive arch rupture disk 3, and improves safety and reliability.This is preferred embodiment, certainly,
Other detachable structures can be used to realize the compression for aligning arch rupture disk.
The oil leak hole is set along the radial disbalance or non-eccentricity of draining valve body, that is to say, that in the outside diameter of draining valve body 1
The heart and connection screw thread central axis, can be processed as eccentric structure or eccentric configuration, with specific reference to oil pumping pump specification used with
And casing tube internal hole size determines.
With reference to figure 3, the positive arch rupture disk 3 is pressure blasting type right arch notch type rupture disk, and concave surface can be directed to transmit
Water body pressure, and when bearing pressure and exceeding setting pressure, rupture disk will be opened to convex surface side positioning, without fragment during explosion, be reacted
Speed is fast, beneficial to quick draining, shortens well workover and accounts for the well time, improves rate when oil well utilizes.
During installation, by the bleeder with a certain position on completion tubular column G.I.H oil well pump, the upper end of draining valve body 1 with
Flow string is connected, and the lower end of draining valve body 1 is connected with oil well pump；Normal production.When needing pump detection and workover, can first rise out
Sucker rod, ground is in oil pipe plus water is pressurized, water body transmits directed pressure, when pressure rise is to design pressure, positive arch
Rupture disk 3 laterally open by directional blasting, and oil pipe is connected with casing, it can be achieved that normal draining purpose at this time.
The above descriptions are merely exemplary embodiments of the present utility model, is not limited to the model of the utility model
Enclose.Any those skilled in the art, the made equivalent change on the premise of the design of the utility model and principle is not departed from
