Abstract
The utility model discloses a gas well drainage gas production plunger designs for solving the problem that conventional plunger only is applicable to the vertical shaft, mainly comprises salvage neck, one-level ball joint, second grade ball joint and seater 4. The plunger piston for gas well drainage and gas production can be salvaged, the structure is simple, the use is convenient, the ball head pin of the ball universal joint can rotate and freely swing in the universal joint shell by utilizing the universal joint ball head, the plunger piston can move upwards or downwards along with the bending of an oil pipe, the number of the plunger piston stages of the universal joint structure can be increased or decreased randomly according to production requirements, and the plunger piston is suitable for gas well drainage and gas production of a directional well.
Description
Technical field
The utility model relates to a kind of drainage gas production plunger in gas well, belongs to oil gas field production gas technology field.
Background technique
Along with the gas field is developed gradually, gas well gets into to be produced the middle and later periods (low-voltage and low-yield stage).Well yield reduces, the fluid-carrying capability variation, and the mineshaft pressure loss becomes big; The part gas well just can not satisfy the requirement that minimum is taken flow quantity when going into operation, thereby makes liquid in shaft bottom or pit shaft, assemble, and then forms hydrops; Have a strong impact on the ordinary production of gas well, cause enormous economic loss.Water pumping gas production is the effective ways that solve " gas well hydrops ", also is to excavate one of important measures of producing aqueous vapor well productive potentialities, raising recovery rate.
Tradition plunger lift water drainage-gas recovery technology is a kind of step production technology; The plunger of institute's extensive use can only be applicable to straight well in the at present domestic and international plunger lift; In recent years, along with the needs of gas field development, directional well quantity showed increased; There are hydrops in part gas well shaft bottom or pit shaft, and the conventional plunger structure can not satisfy the requirement of lifting.
Summary of the invention
The purpose of the utility model is to provide a kind of drainage gas production plunger in gas well, its have can salvage, characteristics simple in structure and easy to use.
The concrete technology contents of the utility model is following:
Drainage gas production plunger in gas well is by fishing neck, one-level universal ball joint, secondary universal ball joint and be located device and constitute:
Minor axis neck in the one-level universal ball joint of band bottom surface screw connects universal joint housing, is provided with the universal joint bulb that can rotate freely swing in the housing, and the ball stud at bulb top is threadedly connected to fishing neck bottom surface screw.
Major axis neck in the secondary universal ball joint of band bottom surface screw connects universal joint housing, is provided with the universal joint bulb that can rotate freely swing in the housing, and the ball stud at bulb top is threadedly connected to one-level universal ball joint minor axis neck bottom surface screw.
Minor axis neck in the one-level universal ball joint of band bottom surface screw connects universal joint housing, is provided with the universal joint bulb that can rotate freely swing in the housing, and the ball stud at bulb top is threadedly connected to secondary universal ball joint major axis neck bottom surface screw.
Plunger is located device through being threadedly connected to one-level universal ball joint minor axis neck bottom surface screw.
The advantage of the utility model is:
Plunger is provided with fishing neck; Can salvage; Simple in structure, easy to use, the ball stud of universal ball joint utilizes the universal joint bulb rotatable and freely swing in universal joint housing, realizes that plunger is with the tubing bending upstream or downstream; And can increase and decrease gimbal structure plunger progression arbitrarily according to the production needs, be applicable to the gas well water pumping gas production of directional well.

Fig. 2 is an one-level universal ball joint structural representation.
Fig. 3 is a secondary universal ball joint structural representation.
Embodiment
Embodiment:
Embodiment referring to figs. 1 through 3 pairs of the utility model further specifies:
Drainage gas production plunger in gas well is by fishing neck 1, one-level universal ball joint W1, secondary universal ball joint W2 and be located device 4 and constitute.
Major axis neck 3 among the secondary universal ball joint W2 of band bottom surface screw connects universal joint housing a, is provided with the universal joint bulb b that can rotate freely swing in the housing a, and the ball stud at bulb b top is threadedly connected to one-level universal ball joint W1 minor axis neck 2 bottom surface screws.
Plunger is located device 4 through being threadedly connected to one-level universal ball joint W1 minor axis neck 2 bottom surface screws.
The working procedure of the utility model is following:
1. plunger is up
Plunger comes downwards to the down-hole and is located device when top under the effect of gravity, and at this moment plunger forms a packing face in oil pipe, and the gas of plunger below can't pass through, and gas is just assembled below plunger, and energy is increased to a certain degree, and gas promotion plunger moves upward.When plunger went upward to lower curved section, the ball stud of universal ball joint utilized the universal joint bulb rotatable and freely swing in universal joint housing, and plunger can be up along with the bending of oil pipe like this; When plunger goes upward to the straight well section, identical with the conventional plunger uplink situation, below go upward to well head under the promotion of gas.After plunger arrived well head, the liquids and gases of plunger upper part were by extraction, and the gas of below is released.
2. plunger is descending
After plunger moved to well head, plunger moved downward under the effect of gravity.Plunger is when the straight well section is descending, and is identical with the descending situation of conventional plunger, is descending under the effect of gravity; When plunger comes downwards to kickoff point (KOP); The ball stud of universal ball joint utilizes the universal joint bulb rotatable and freely swing in universal joint housing; Plunger can be descending along with the bending of oil pipe like this, when plunger comes downwards to the down-hole and is located device, and the circulation of beginning next cycle.
