Abstract

The design discloses a kind of tackle pumping unit for two oil wells, belong to improvement to the individual well oil pumper, solved the problem of the public pumping unit of twin-well, its major technique feature is: put an individual well pumping unit between twin-well, remove counterweight, walking beam and support thereof, with the counterweight each other of sucker rod and downhole hardware thereof in two mouthfuls of wells, wherein crank connecting link [6] links to each other with a coaster [7], coaster is put on the guide rail that fixed support [16] are arranged [15], at the two mouthfuls of well [14A in coaster two ends and traction, 14B] wire rope [8] of sucker rod connects, wire rope walk around on the well head fixed pulley respectively with well in polished rod [11] hang by connector and join, under motor drives, a coaster left side, the right reciprocating motion, drive in two mouthfuls of wells on the sucker rod one, aspirate underground crude oil once in turn, realize the purpose of two mouthfuls of down-hole crude oil of an equipment suction,, can reduce the twin-well investment owing to reduced some parts, energy conservation, and improved the utilization rate of pumping unit.

Description

Tackle pumping unit for two oil wells

The design relates to the tackle pumping unit for two oil wells of the public pumping unit of a kind of twin-well, belongs to mechanical oil pumper.

At present, generally use beam type individual well oil pumper on the oil field, though the stable performance of this kind oil pumper can only be aspirated crude oil from a bite well, utilization rate of equipment and installations is low, based on this because of, the design is proposed.

The design's purpose: improve individual well pumping unit utilization rate, making a cover pumping unit is the underground crude oil of the public suction of twin-well; The technical scheme that realizes its task is: put an individual well pumping unit between twin-well, remove counterweight, walking beam and support, with the counterweight each other of sucker rod and downhole hardware thereof in two mouthfuls of wells, wherein crank connecting link links to each other with coaster, coaster is put to be had on the support bracket fastened guide rail, wire rope at the two mouthfuls of well sucker rods in coaster two ends and traction is connected, wire rope walk around on the well head fixed pulley respectively with well in polished rod hang by connector and join, the rotation of motor drives crank connecting link, make about coaster and move back and forth, drive in two mouthfuls of wells on the sucker rod one, once underground crude oil is alternately aspirated in motion, realizes the purpose of two mouthfuls of underground crude oil of well of a cover pumping unit suction.

Below in conjunction with accompanying drawing the design is illustrated in greater detail:

Fig. 1 is a twin-well travelling block formula pumping unit assembling diagrammatic sketch;

Fig. 2 is pulley yoke master, left view;

By shown in Figure 1, the design is the improvement to the individual well pumping unit, its equipment has motor [1], belt [2], belt pulley [3], reduction box [4], crank connecting link [6], these device assembles postposition between twin-well, compare with original equipment, balance weight and support and walking beam have been removed, horse head and support, what be connected with crank connecting link [6] is a coaster [7], it is put on the guide rail that fixed support [16] are arranged [15], and the coaster two ends are connected with the wire rope [8] of two mouthfuls of wells of traction [14A, 14B], wire rope walk around on the well head two fixed pulleys [9] respectively with well in polished rod [11] hang by connector [12] and join, fixed pulley [9] is loaded on the fixed support [10]; The trend of coaster is on the two well head lines of centres;

Pump setting depth and output as two mouthfuls of wells are all identical, then sucker rod and install counterweight each other in two mouthfuls of wells; Aboveground to state situation inequality when two mouthfuls, needs to be provided with balance weight on polished rod [11] and wire rope [8] connector and hang anchor [13], hangs up suitable balance weight as calculated, makes the suffered static load balance in two ends of coaster [7].

The design is applicable to the Liang Koujing that well spacing is nearer, such as cluster well, offshore platform well, dense well spacing and infill well, the Liang Koujing far away to well spacing, can establish a plurality of uniform pulley yokes [18] at Liang Koujing and equipment room, as shown in Figure 2, to keep the levelness of steel wire rope, can prevent from being subjected to external force to produce waving and vibrate. [17,19] are two fixed pulleys, steel wire rope on the figure.

This device has a bite well to break down in running, needs to shut down operation; After the motor stall, remove the steel wire rope of this well of traction, and hang up suitable counterweight, become individual well production by twin-well; After the fault well is repaired, can recover twin-well production. [5] are bases on Fig. 1. During installation, make connecting rod [6] in the crank connecting link in motion process, will produce the oblique force that dips down to the coaster that connects, avoid coaster in the reciprocating motion process, to derail.

The design's implementation result:

With the sucker rod in two mouthfuls of wells and downhole hardware thereof counterweight each other, drive the left and right reciprocating motion of coaster [7] by power, realize power, the drive apparatus of two mouthfuls of public oil pumpers of mechanical oil well, two mouthfuls of wells have been produced swabbing action in turn, improved utilization rate of equipment and installations and energy conservation; Owing to reduced some parts, can reduce twin-well investment and cost of production.

Claims

1, the design relates to a kind of petroleum machinery oil recovery tackle pumping unit for two oil wells, it is characterized in that:

1) between twin-well, puts an individual well pumping motor, drive apparatus, wherein crank connecting link [6] links to each other with a coaster [7], coaster is put on the guide rail that fixed support [16] are arranged [15], and at the two mouthfuls of well [14A in coaster [7] two ends and traction, 14B] wire rope [8] connect, wire rope walk around on the well head two fixed pulleys [9] respectively with well in polished rod [11] join by connector [12] suspension;

2) trend of coaster [7] is on the two well head lines of centres;

3) on polished rod [11] and wire rope [8] connector, be provided with balance weight and hang anchor [13].

2, tackle pumping unit for two oil wells as claimed in claim 1 is characterized in that: the well far away to well spacing, can establish a plurality of pulley yokes [18] betwixt.
