Description
One, technical field
The utility model is the downhole tool of oilfield production usefulness, and particularly a kind of downhole oil gas separating device is applicable to the pumpingh well that air content is big.
Two, background technology
In oil well, the well air content that has is big, and when pumping with oil well pump, the gas-liquid ratio that enters in the oil well pump is big, reduces well liquid discharge capacity, and oil well output is low, and pump efficiency is low, and after air content surpassed certain value, oil well pump also gas lock can take place, and causes oil well not fuel-displaced.In order to reduce the influence of gas to oil well pump work, the oil field is often adopted to install under pump and is utilized the gas anchor of slippage effect and Gravity Separation simply to separate, prevent that gas from entering in the pump, though this gas anchor have certain effect, for the big oil well weak effect of air content.The multistage separating gas anchor is adopted at the scene sometimes, though certain liquid gas separating effect, complex structure, cost of production height are arranged.
Three, summary of the invention
The purpose of this utility model provides a kind of downhole oil gas separating device, is installed under the oil well pump in the pumpingh well, and gas-liquid is separated, and reduces the gas that enters oil well pump, improves the pump efficiency of oil well pump, improves the oil well economic benefit.
The purpose of this utility model is achieved in that urceolus is suspended on outside the suspended tubes, vent valve is installed between urceolus and the suspended tubes, the urceolus bottom connects with coupling head top major thread, the suspended tubes bottom connects with inner core top, and the inner core bottom connects with coupling head top minor thread, mounting center pipe in the inner core, between inner core and the central tube steel wire is arranged, steel wire is wrapped in the central tube external surface, and the central tube bottom connects with the commutation joint, and the commutation joint is welded on the side direction import department of inner core bottom.
The beneficial effects of the utility model are: before well liquid flows to oil well pump, make progress downward screw settling of gas-liquid mixture separates, make full use of gravitational difference and slippage effect between gas, liquid and realize spiral and gravity dual efficient separation between liquid, gas, reduce the gas that enters oil well pump, improve the pump efficiency of oil well pump, improve the oil well economic benefit.
Four, description of drawings
Accompanying drawing is an assembling drawing of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Urceolus 3 is suspended on outside the suspended tubes 1, vent valve 2 is installed between urceolus 3 and the suspended tubes 1, urceolus 3 bottoms connect with coupling head 8 top major threads, suspended tubes 1 bottom connects with inner core 4 tops, and inner core 4 bottoms connect with coupling head 8 top minor threads, mounting center pipe 5 in the inner core 4, between inner core 4 and the central tube 5 steel wire 6 is arranged, steel wire 6 is wrapped in central tube 5 external surfaces, and central tube 5 bottoms connect with commutation joint 7, and commutation joint 7 is welded on the side direction import department of inner core 4 bottoms.Coupling head 8 bottoms connect with decanter type gas anchor 9.The side direction import department that the side entrance of commutation joint 7 is aimed at inner core 4 bottoms, commutation joint 7 bottoms are obstructed.
Before gas-liquid mixture flow to oil well pump, gas-liquid mixture was through the 9 preliminary gas-liquid separations of decanter type gas anchor, and gas moves upward from the outside of decanter type gas anchor 9, can not enter the work that influences oil well pump in the pump.After initial gross separation, the gas-liquid mixture of the low ratio runner spiral of 6 formation of the steel wire between inner core 4 and central tube 5 again rises, carry out spiral separation, gas after the separation is expelled in the sleeve pipe from vent valve 2, liquid flows to the side direction inlet port that the annular space between urceolus 3 and inner core 4 down enters commutation joint 7, makes progress in the central tube 5 to be extracted out by oil well pump through suspended tubes 1 again.
Claims (3)
1, a kind of downhole oil gas separating device, it is characterized in that: urceolus (3) is suspended on outside the suspended tubes (1), vent valve (2) is installed between urceolus (3) and the suspended tubes (1), urceolus (3) bottom connects with coupling head (8) top major thread, suspended tubes (1) bottom connects with inner core (4) top, inner core (4) bottom connects with coupling head (8) top minor thread, the interior mounting center pipe of inner core (4) (5), between inner core (4) and the central tube (5) steel wire (6) is arranged, steel wire (6) is wrapped in central tube (5) external surface, central tube (5) bottom connects with commutation joint (7), and commutation joint (7) is welded on the side direction import department of inner core (4) bottom.
