Abstract

An injection and extraction integrated oil-well pump of the utility model which belongs to mechanical products and achieves the integration of injection and extraction, is mainly used for the aspect of oil industry and is a tool used for oil well production of oil field. The utility mode is characterized in that the structure is bypass type. One end is assembled by a lower sub (1) and a standing valve assembly (2), and a gas injection open sub assembly (3) and a gas injection sealed body (4). The other end is a coupling (15) on the pump matched and connected with a draw rod (14). The draw rod (14) is mounted with a plunger (13) and a guiding traveling valve (12). One side of a middle part sub (10) connects with the pump barrel, and the other side of the middle part sub (10) connects with a protecting tube (9) and a gas injection outer sealed body (4). The inside of the middle part sub (10) is mounted with a push rod (7) and a spring (5). The utility model which has the major advantages of simple structure, reliable working performance, broad application, and safe operation, decreases the working cost and labor intensity and increases the labor efficiency and field output.

Description

Notes are adopted the one oil well pump

One, technical field

The utility model belongs to a kind of engineering goods, being mainly used in the petroleum industry aspect, is that a kind of oilfield recovers the oil and produces tool using, particularly for the heavy crude reservoir of steam injection thermal recovery, can be disposable realization annotate vapour and oil recovery two procedures and production process, realized annotating adopt integrated.

Two, background technique

At present, at petroleum industry system, the exploitation of the heavy crude reservoir of steam injection thermal recovery, annotating vapour and producing oil recovery process is that substep is finished.

1, the heavy crude reservoir of steam injection thermal recovery, oil well are at first finished steam injection process before production, and then pump production down, and steam injection string and flow string are separately independently.

2, the oil well pump that uses in the flow string is conventional oil well pump.

Find to have the following disadvantages by using: steam injection string and flow string are separately independently, have increased operating cost and have accounted for the product time.In addition, annotate vapour, the oil well pump that must more renew increases cost at every turn.

Three, summary of the invention

According to above-mentioned defective, the purpose of this utility model provides a kind of notes and adopts the one oil well pump, solve to annotate and to adopt the oil well pump of one, the utility model mainly by standing valve, annotate that vapour is opened connector assembly, annotated steam packing body assembly, pump barrel, plunger, carry parts such as pump pipe nipple, joint and form the bypass type structure.Notes vapour is opened connector assembly and annotated steam packing body assembly is to annotate to adopt one oil well pump critical component, make plunger descending when annotating vapour, when going downwards to certain position, open the notes vapour by-pass hole of annotating the steam packing body, simultaneously, the push rod that notes vapour is opened joint backs down the plunger valve ball, realizes the connection of tube column, oil reservoir.Notes are adopted the valve body, pump barrel, plunger pump upper connection, standing valve of one oil well pump etc. and are all adopted the standard piece configuration to use.Model utility can realize the tandem product of pumps such as Φ 38, Φ 44, Φ 56, Φ 70, Φ 83, can satisfy the needs that all kinds of thick oil well steam injection thermal recoveries are produced.

Its beneficial effect is that simple in structure, reliable working performance, using scope are wide, construction safety, reduction operating cost, reduce labor intensity, improved efficiency, reduces accounting for and produces the activity duration, improves field output.

Four, description of drawings

Accompanying drawing is a structural representation of the present utility model.

Among the figure 1, lower contact, 2, the standing valve assembly, 3, annotate vapour and open connector assembly; 4, annotate vapour external sealed body, 5, spring, 6, annotate seal in the vapour; 7, push rod, 8, the spring landing nipple, 9, protective tube; 10, center contact, 11, pump barrel, 12, the guiding traveling valve; 13, plunger, 14, pull bar, 15, box cupling on the pump; A, notes steam vent

Five, mode of execution

As seen from the figure, the utility model is the bypass type structure, one end is opened connector assembly 3 and is annotated 4 combinations of vapour external sealed body by lower contact 1 and standing valve assembly 2, notes vapour, spring 5 is installed in annotating vapour external sealed body 4 and annotates seal 6 in the vapour, 4 places are shaped on notes steam vent A at notes vapour external sealed body, the other end of the present utility model by pump on box cupling 15 be connected with pull bar 14, pull bar 14 be equipped with plunger 13, the guiding traveling valve 12; Center contact 10 1 sides are connected with pump barrel, and opposite side connects protective tube 9, annotates vapour external sealed body 4, push rod 7 is installed in it is constituted with spring 5.At the scene in the work progress, except that plunger is gone into the well with sucker rod, other each part assembles with in the lower going-into-well after the oil pipe connection, behind the well depth position of arrival design, by the boll-weevil hanger installing and locating, plunger is with in the sucker rod lower going-into-well, when plunger arrives certain position, under the effect of sucker rod gravity, promote to annotate seal 6 in the vapour, when while pressure spring 5 moves downward together, when moving to bottom position, open and annotate steam vent A, simultaneously push rod 7, move upward relatively, enter in the plunger mesopore sealing valve, back down the guiding travelling valve, realized being communicated with of oil pipe and oil reservoir, can finish oil well then smoothly and annotate vapour, after annotating vapour and finishing, on carry plunger, annotate seal 6 return under the effect of spring 5 elastic force in the vapour, close the notes steam vent and adjust over-stroke, ordinary production drives a well.Thereby the realization notes are adopted integrated.
