Abstract
The utility model discloses a blowout preventer of an oil well pump, which comprises a connecting body; the connecting body comprises a fixed sliding sleeve (2); the outer wall of the fixed sliding sleeve is provided with a plurality of oil drainage holes (5); the movable sliding sleeve (4) is fixed between the connecting body and the fixed sliding sleeve (2) through a shearing pin (6); the movable sliding sleeve (4) blocks the oil drainage hole (5). And (3) pressing the movable sliding sleeve (4), enabling the movable sliding sleeve (4) to move downwards, leaking the oil drainage hole (5) at the lower end of the fixed sliding sleeve (2), and enabling liquid in the well to flow into the pump barrel from the oil drainage hole (5) to be released successfully. The problems that liquid is easy to flow back to cause pollution in pipe laying operation, a sucker rod is easy to block in the process of laying the pipe and the like are solved.
Description
Technical field
The utility model relates to a kind of underground blow-out preventing devices.
Background technique
Under underground work inspection during pump construction down tube, since well head installs preventer, borehole pressure is with downhole pipe
The increase of column depth and increase, especially lowering-in operation when, the liquid returned out in casing is returned by oil pipe to well head, is be easy to cause
Environmental pollution.Moreover, crude oil from oil-well pump bottom enters oil pipe in well, it will cause lower sucker rod and be hampered, anti-flushing well etc. is taken to arrange
The construction that resumes operation is applied, equipment and manpower are wasted, extends the well workover time.
Summary of the invention
In view of this, the present invention provides a kind of spray-proof device of oil-well pump, solve lowering-in operation and are easy to appear liquid
The problems such as row of returning pollutes and lower sucker rod is hampered.
For achieving the above object, a kind of spray-proof device of oil-well pump characterized by comprising
Connect ontology；
It include fixed sliding sleeve in the connection ontology；
The outer wall of the fixed sliding sleeve has oil leak hole；
By cutting the fixed movable sliding sleeve of pin between the connection ontology and the fixed sliding sleeve；
The activity sliding sleeve blocks the oil leak hole.
Preferably, the connection ontology, comprising:
Top connection and lower contact；
The top connection is threadedly coupled with the lower contact；
The fixed sliding sleeve is fixed in the top connection；
The activity sliding sleeve is fixed in the lower contact.
Preferably, between the fixed sliding sleeve and the top connection and between the movable sliding sleeve and the fixed sliding sleeve
Sealing ring is respectively set.
Preferably, the lower part of the fixed sliding sleeve is arranged in the oil leak hole, and uniformly distributed along the circumferential direction of the fixed sliding sleeve.
Preferably, the oil leak hole is arranged on the fixed sliding sleeve according to upper and lower staggered mode.
The utility model has the following beneficial effects:
The spray-proof device of oil-well pump of the utility model can recycle in time the liquid returned out in casing in lowering-in operation
To effluent oil recovery device, the phenomenon that when lower sucker rod will not be hampered, blowout prevention, preventing polluting effect are good, shorten Zhan Jingshi
Between, it greatly improves work efficiency, obtains the approval of site operation personnel.
Detailed description of the invention
By the description below with reference to attached drawing to the utility model embodiment, the above-mentioned and other mesh of the utility model
, feature and advantage it is apparent, in the accompanying drawings:
Fig. 1 is the structural schematic diagram of the spray-proof device of oil-well pump of the utility model embodiment.
Specific embodiment
The utility model is described below based on embodiment, but it is worth noting that, the utility model is simultaneously unlimited
In these embodiments.It is detailed to describe some specific detail sections below in the datail description of the utility model.So
And for the part of no detailed description, the utility model can also be understood completely in those skilled in the art.
In addition, it should be understood by one skilled in the art that provided attached drawing is simply to illustrate that the utility model
Objects, features and advantages, attached drawing are not to be actually drawn to scale.
Meanwhile unless the context clearly requires otherwise, "include", "comprise" etc. otherwise throughout the specification and claims
Similar word should be construed as the meaning for including rather than exclusive or exhaustive meaning；That is, being " including but not limited to "
Meaning.
Fig. 1 is the structural schematic diagram of the spray-proof device of oil-well pump of the utility model embodiment.As shown in Figure 1: a kind of oil pumping
Pump blowout hookup, including connection ontology；Connecting in ontology includes fixed sliding sleeve 2, and the outer wall of fixed sliding sleeve has several oil leak holes
5；It connects by cutting the fixed movable sliding sleeve 4 of pin 6 between ontology and fixed sliding sleeve 2, movable sliding sleeve 4 blocks the oil leak hole 5.
Further, connection ontology includes top connection 1 and lower contact 7, and top connection 1 is threadedly coupled with lower contact 7；It is fixed to slide
Set 2 is fixed in top connection 1, and movable sliding sleeve 7 is fixed in lower contact 7.
Further, it is respectively set between fixed sliding sleeve 2 and top connection 1, and between movable sliding sleeve 4 and fixed sliding sleeve 2 close
Seal 3.
Further, the lower part of fixed sliding sleeve 2 is arranged in oil leak hole 5, and uniformly distributed along the circumferential direction of fixed sliding sleeve 2.
Further, oil leak hole 5 is arranged on fixed sliding sleeve 2 according to upper and lower staggered mode.Not influence draining
Amount preferably beats ∮ 10mm*20 oil leak hole 5 on fixed sliding sleeve 2.
Specifically, it is illustrated in conjunction with the course of work of the Fig. 1 to the spray-proof device of oil-well pump of the utility model:
Spray-proof device of oil-well pump is mounted between oil pump sleeve and standing valve, detects pressure testing by testing pump installation
10Mpa, 15min, which are not pierced, not to be leaked for qualification.Then by connector entirety G.I.H, it is self-possessed by the full well body of rod, makes piston bottom
Portion is pressed on the movable sliding sleeve 4 of blowout hookup, the cutting pin 6 between movable sliding sleeve 4 and fixed sliding sleeve 2 is cut, activity is sliding
4 downlinks are covered, the oil leak hole 5 of fixed 2 lower end of sliding sleeve is leaked out, liquid flows into pump barrel from oil leak hole 5 in well, discharges successfully.
Embodiment described above is only to express the embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
