Abstract
The utility model discloses an oil well associated gas power oil pumping machine which is composed of a horse head walking beam, and a supporting frame. The walking beam is fixed on the supporting frame, the tail part of the supporting support is provided with a balancing weight, and a pneumatic device is arranged between the horse head and the supporting frame. The utility model utilizes pressure generated by oil well associated gas to push a piston to make up and down motion to drive the oil pumping machine to carry out pumping operation. As a result, the energy is saved, the maintenance cycle is extended, and the work efficiency is raised.
Description
The utility model relates to a kind of new type power pumping unit, particularly a kind of pumping unit that utilizes the oil well associated gas to do power.
China has the considerable part oil well to be rich in high pressure draught at present; and the pumping unit that uses on the well site is all done power with electric energy; power consumption becomes a high reason of cost for oil production greatly; the other lawless person often steals the electric power facility on the well site; cause shutdown of pumping machine; influence the production of crude oil, thereby Electric oil suction unit there is significant limitation in some places.
The purpose of this utility model just provides a kind of oil well associated gas power pumping unit.
The purpose of this utility model is achieved in that oil well associated gas power pumping unit is made up of horse head walking beam, support, and walking beam is fixed on the support, and the afterbody of support is equipped with equilibrate counterweight, is provided with Pneumatic actuator between horse head and support.Pneumatic actuator is made up of piston rod, piston, cylinder body, and piston rod upper end is fixed on the walking beam, the lower end plug of taking over a job, piston rod is provided with upper and lower spacing, between upper and lower spacing controlling rod is housed, controlling rod is enclosed within the outside of cylinder body, and the bottom of cylinder body has suction port and air outlet.
The pressure that the utility model utilizes the oil well associated gas to produce promotes piston up-down, carries out swabbing operation thereby drive pumping unit, has saved the energy, has prolonged the repair cycle, has improved working efficiency.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1: the structural representation of oil well associated gas power pumping unit;
Fig. 2: Pneumatic actuator structural representation;
Among the figure: 1-well head four-way, 2-horse head, 3-walking beam, 4-Pneumatic actuator, 5-support,
6-equilibrate counterweight, 7-upper limit position block, 8-lower position block, 9-piston rod, 10-piston,
11-cylinder body, 12-controlling rod, 13-suction port, 14-air outlet;
As shown in Figure 1, oil well associated gas pumping unit is by horse head 2, walking beam 3, support 5 is formed, walking beam 3 is fixed on the support 5, afterbody at support 5 is equipped with equilibrate counterweight 6, between horse head 2 and support 5, be provided with Pneumatic actuator 4, as shown in Figure 2, Pneumatic actuator 4 is by cylinder body 11, piston 10, piston rod 9 is formed, piston rod 9 upper ends are fixed on the walking beam 3, take over a job and fill in 10 in the lower end, and piston rod 9 is provided with, lower position block 7,8, have suction port 13 and air outlet 14 in the bottom of cylinder body 11, on piston rod 9, lower position block 7, be provided with controlling rod 12 between 8, controlling rod 12 is enclosed within the outside of cylinder body, and it is used for controlling advancing of cylinder body 11, the air outlet.
During use, pumping unit is fixed on the wellhead platform, the well head associated gas is connected through pipeline on the suction port 13 of cylinder body 11 by the exhaust flange of well head four-way 1, and associated gas enters in the cylinder body 11, forms pressure, jacking piston 10 and piston rod 9, thereby piston rod 9 jack-up walking beams 3, when piston rod 9 rose to certain altitude, the lower position block 8 of piston rod 9 had been with controlling rod 12 up, at this moment the inlet close of cylinder body 11, open the air outlet, and under the effect of horse head gravity, piston descends, when piston rod 9 goes downwards to upper limit position block 7, controlling rod 12 is closed the air outlet, opens suction port, once more with walking beam jack-up, and so forth, form the pumping of pumping unit.
