The heart uniformly offers multiple feed liquor steam vents, as shown in Figure 6；Feed liquor steam vent both entered passage as liquid, also can conduct
The passing away of gas；
Feed liquor steam vent can be opened in top connection bottom, i.e. the bottom of top connection is outwardly to form annular outer portion, enters
Liquid steam vent is opened in its annular outer portion；What Fig. 5 and Fig. 6 of the present embodiment showed is such a mode.
Feed liquor steam vent can also be opened in the top of outer tube, i.e. the upper inside wall of outer tube is inwardly projecting to be formed in annular
Convex portion, feed liquor steam vent are opened in its annular interior protuberance；
Feed liquor steam vent can be also opened on an annular element, outside the inwall connection top connection bottom of the annular element
Wall, the upper inside wall of the outer wall outer sleeve for connecting of annular element.
In addition, the volume of the annular space in Fig. 5 indicated by L1 between corresponding subsiding center pipe and outer tube is taken out more than two
The volume of oil pump stroke.And this point is the optimal main points of this gas anchor effectiveness performance, specifically see lower section：
Principle Analysis：It is sliding from fluid that formation fluid is constantly in gas before decanter type gas anchor inlet opening is entered
De- state.After feed liquor steam vent enters decanter type gas anchor annular space, when oil pumper is in down stroke, fluid, which is in, to be stagnated
During state, the gas in the fluid in annular space between outer tube and subsiding center pipe slips again.Corresponding to indicated by L1
The annular space volume of outer tube and subsiding center pipe is more than or equal to the volume of two oil pumping pumps stroke, and each stroke is by corresponding to L1
Annular space lower half liquid suction subsiding center pipe flows into lower half, gas anchor external fluid hence into oil well pump, first half liquid
Enter the annular space first half again by feed liquor steam vent, gas continues to slip from fluid in oil well pump down stroke stagnation.Gas
Body slips discharged from feed liquor steam vent upwards.Moving in circles makes to be free of gas into the fluid in pump every time.So as to reach oil pumping
Pump coefficient of fullness is high, improves pumping efficiency.
Although the space that the outer tube body and change buckle joint and plug below L1 collectively form can be also played solid phase
The effect that composition is separated and deposited from liquid, but because length and volume are relatively small, therefore can become as shown in figs. 4 and 7
A sand sediment pipe with the above two intercommunications can also be set up between buckle joint and plug, sand sediment pipe top and becoming between buckle joint bottom leads to
Cross connecting hoop both are affixed, and both open butt joints connections, the bottom of sand sediment pipe is threadedly coupled with plug.Into in annular space
Solid-phase component in fluid is lowered into sand sediment pipe (and plug) in shear force and gravity collective effect.The length of sand sediment pipe according to
Solid-phase component content difference and change.Sand sediment pipe is set up, and entire length and volume is all had a distinct increment, enhancing solid-liquid point
From, deposition effect, and it can extend and the time is intended for single use, reduce the maintenance frequency for removing sedimentary sand bodies.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
