In use, third top connection 1 is connect with oil pipe lower thread, tail pipe is connected to 27 lower end of the first lower contact,
Then the device is transferred in casing with oil pipe, until the first inlet opening 23 is located at the liquid level lower section of well liquid in casing, oil pumping
After pump startup, well liquid will be entered between the first outer tube 24 and inner tube 25 by the first inlet opening 23, in 25 outer rim of inner tube
Under the action of upper first helical blade 31, well liquid spiral downlink, under gravitational and centrifugal forces, sand in well liquid will be to
First outer tube, 24 inner edge direction close to and downlink, at this time from well liquid escaping gas will it is close to 25 direction of inner tube and on
It is gathered in after row in the connection coupling 22 of 24 upper end of the first outer tube, after well liquid enters inner tube 25, the sand in well liquid will
Tail pipe, the gas assembled in 24 upper end connection coupling 22 of the first outer tube are fallen by the desilting channel 26 in the first lower contact 27
It just will push ball sealer 12.2 after gradually increasing and arrange from aperture 12.1 into oil jacket annulus, remove drop and portion gas
Well liquid enters the first water conservancy diversion by inner tube 25 and exchanges in pipe 21, because the internal diameter of the first water conservancy diversion exchange pipe 21 is greater than inner tube 25
Internal diameter, the pressure and pressure for flowing through the well liquid of the first water conservancy diversion exchange pipe 21 are reduced, therefore when well liquid enters the friendship of the first water conservancy diversion
It changes behind 21 inside of pipe and there is the gas of part to escape from well liquid and assemble and be expanded into larger bubble, and as well liquid passes through first
Top connection 20 enters in the second lower contact 19 and isolated tube 15,
Under the barrier effect of partition 17, well liquid enters the second outer tube 14 and isolated tube by the second inlet opening 18
In cavity between 115, while the bulb-breaking device in the second inlet opening 18 can be by the bubble destruction in well liquid, so that in bubble
Gas evolution, enter the well liquid uplink between the second outer tube 14 and isolated tube 15 in cavity and from third inlet opening 13 into
Entering the downlink into the cavity between central tube 16 and isolated tube 15, well liquid will change flow direction after third inlet opening 13, this
When gas between central tube 16 and isolated tube 15 will uplink and in the connection coupling 22 of 14 upper end of the second outer tube
Aggregation, since the pumping of well liquid is flowed, the gas assembled in 14 upper end connection coupling 22 of the second outer tube will after gradually increasing
It pushes ball sealer 12.2 and arranges from aperture 12.1 into oil jacket annulus, be gathered in the connection coupling 22 of 14 upper end of the second outer tube
After interior gas discharge, the intracorporal pressure reduction of air accumulation chamber forms relatively negative in 14 upper end connection coupling 22 of the second outer tube
Pressure, meanwhile, the pressure that well liquid flows to top at change is minimum, therefore the well liquid between central tube 16 and isolated tube 15 can constantly have
Gas evolution and uplink be gathered in the connection coupling 22 of 14 upper end of the second outer tube, after well liquid enters central tube 16 on
Row, the flow direction of well liquid change again, have portion gas at this time and flow to change place evolution and uplink aggregation from well liquid again
In the connection coupling 22 of 14 upper end of the second outer tube, the gas assembled in the connection coupling 22 of 14 upper end of the second outer tube continues
Discharge, the well liquid entered in central tube 16 flow through the second water conservancy diversion exchange pipe 11, the second top connection 10, the entrance of third lower contact 9
To third water conservancy diversion exchange pipe 8 in because the second water conservancy diversion exchange pipe 11 internal diameter be equal to third water conservancy diversion exchange pipe 8 internal diameter, second
The internal diameter that water conservancy diversion exchanges pipe 8 is greater than the internal diameter of central tube 16, therefore when well liquid flows through the second water conservancy diversion exchange pipe 11 and third water conservancy diversion
When exchanging pipe 8, the gas evolution of part is had, gas and well liquid enter in third outer tube 6 by the through-hole 29 of box cupling 7,
Under the action of 5 the second helical blade of outer rim 32 of interior bar, well liquid spiral uplink, under the influence of centrifugal force, gas is to 5 side of interior bar
To close to and uplink after be gathered in cyclonic separation umbrella 3, after the gas in cyclonic separation umbrella 3 gradually increases, gas will gram
Valve ball 2 is jacked up heel row into oil jacket annulus by the gravity for taking valve ball 2, and well liquid, which enters, passes through fluid hole 28 in cyclonic separation chamber 4
It enters in oil pipe and is extracted.
According to how much increases of well liquid in oil well and gas or gas-liquid two-phase Gravity Separation tapping equipment can be reduced
Joint number carries out gas-liquid separation using the well liquid that more piece gas-liquid two-phase Gravity Separation tapping equipment is big to liquid measure, air content is high.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
