Abstract
The utility model relates to a kind of variable diameter plunger with support frame, plunger includes: plunger body, compressed spring, support frame, rubber ring;It is characterized by: fluted in the middle part of plunger body, groove internal upper part point has compressed spring, compressed spring lower hinge support frame, and the two joining place is movable end;Support frame lower end is fixed on groove bottom in the form of fixed-hinged support;Two top of support framees are hinged, and stud with rubber ring on top.When plunger uplink in well, if meeting complex hole condition, rubber ring is contacted with the borehole wall, and the borehole wall compresses compressed spring the active force of plunger, and support frame retracts in groove, and diameter of plunger becomes smaller, will pass through Holes of Complicated Wells section;After complicated well section, hole diameter becomes larger, and spring-relaxation, diameter of plunger becomes larger, and continues uplink.The utility model has the following beneficial effects: diameter of plunger is alterable, and compressed spring and support frame are detachable, replaceable, low in cost, convenient for promoting.
Description
Technical field
The utility model relates to a kind of variable diameter plungers for one of oil gas field gas producing technology with support frame, belong to gas
Hide water pumping gas production field.
Background technique
Plunger lift is substantially jat special shape, is installed in lifting gas and between lifting liquid load
The seal interface device of one solid, reduces the channelling of gas and the falling of liquid, to effectively improve gas energy
Lifting efficiency greatly improves production well yield.Plunger lift well during normal production, reciprocating motion of the plunger in oil pipe,
Play the role of wax removal, wax control and scale removal, suitable for easy wax deposition, the oil/gas well of fouling.
But in actual application, hole condition is complicated, its immutable diameter of conventional plunger, in case of well radius variations amplitude compared with
Big situation may be blocked, so that serious down-hole accident occurs, impact to safety in production.This patent is exactly to be
Solve the problems, such as that plunger body diameter is immutable now, to adapt to the complicated well of hole condition variation, plunger body can change in well
Variable diameters, structure is simple, and cost is relatively low.
Summary of the invention
The purpose of this utility model is: providing a kind of reducing plunger with support frame.
In order to achieve the above object, the utility model uses following technical scheme: a kind of variable diameter plunger with support frame, column
Plug includes: plunger body, compressed spring, support frame, rubber ring;It is characterized by: fluted in the middle part of plunger body, in groove on
There is a compressed spring in part, compressed spring lower hinge support frame, and the two joining place is movable end, force way be middle hinge about
Beam force;Support frame lower end is fixed on groove bottom in the form of fixed-hinged support, and force way is fixed-hinged support restraining force;
Two top of support framees are hinged, and stud with rubber ring on top.
The utility model has the following beneficial effects: (1) diameter of plunger is alterable;(2) compressed spring and support frame are removable
It unloads, it is replaceable;(3) low in cost, convenient for promoting.
Detailed description of the invention
Fig. 1 is a kind of main view of the variable diameter plunger with support frame of the utility model.
In figure: 1. plunger bodies, 2. compressed springs, 3. support frames, 4. rubber rings.
Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of variable diameter plunger with support frame, plunger includes: plunger body 1, compressed spring 2, support frame
3, rubber ring 4;It is characterized by: fluted in the middle part of plunger body, groove internal upper part point has compressed spring 2,2 lower part of compressed spring
Hinged support frame 3, the two joining place are movable end, and force way is middle hinge restraining force;3 lower end of support frame is hinged with fixation
The form of seat is fixed on groove bottom, and force way is fixed-hinged support restraining force;Two 3 tops of support frame are hinged, and
Top studs with rubber ring 4.
When plunger uplink in well, if meeting complex hole condition, rubber ring 4 is contacted with the borehole wall, effect of the borehole wall to plunger
Power compresses compressed spring 2, and support frame 3 retracts in groove, and diameter of plunger becomes smaller, will pass through Holes of Complicated Wells section;Pass through Holes of Complicated Wells
Duan Hou, hole diameter become larger, and spring-relaxation, diameter of plunger becomes larger, and continue uplink.
The utility model has the following beneficial effects: (1) diameter of plunger is alterable;(2) compressed spring and support frame are removable
It unloads, it is replaceable;(3) low in cost, convenient for promoting.
