Before the raw liquid delivered to the oil pump, the raw liquid is delivered to the helix separating component and the current diverter; and with the gravity difference of the liquid, gas and sand and slip, the liquid, the gas and the sand are whorled and separated gravitationally; therefore, the gas and the sand go into the oil pump are reduced, the efficiency of the oil pump is increased, and the damage of the sand to the oil pump is reduced or eliminated; thus, the producing period of the oil pump is prolonged and the economic effect of the oil pump is increased.
Description
One, technical field
The utility model is the downhole tool of oilfield production usefulness, and particularly a kind of spiral bell-type gas and sand anchor is applicable to that air content is big, and serious oil well shakes out.
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 after air content surpassed certain value, oil well pump also gas lock can take place, and causes oil well not fuel-displaced.In oil well, the well sand content height that has, sand grains enter and cause the oil well pump wearing and tearing in the oil well pump, meeting holddown when serious, and oil well pump can not be worked, and necessary workover treatment reduces oil well output, needs a large amount of operating costs, the oil well deficiency in economic performance.In order to reduce the influence to oil well pump of gas, sand, the oil field is often adopted gas anchor or the sand anchor that utilizes slippage effect and Gravity Separation is installed under pump, simply separates, and prevents that gas, sand from entering in the pump.Though have certain effect, big for air content, shake out the oil well weak effect serious, though the multistage separating gas anchor of field by using, sand anchor result of use are good, complex structure, cost of production height.
Three, summary of the invention
The purpose of this utility model provides a kind of spiral bell-type gas and sand anchor, be installed under the oil well pump in the pumpingh well, gas sand is separated, reduce the gas and the sand grains that enter oil well pump, improve the pump efficiency of oil well pump, reduce or eliminate the infringement of sand grains, prolong the production cycle property of oil well, improve the oil well economic benefit oil well pump.
The purpose of this utility model is achieved in that by top connection, feed tube, isocon, divide fluid, the leather cup joint, leather cup, crossover sub, central tube, flight, umbrella crown, outer tube, lower contact is formed, top connection is inner down to be connected with feed tube top, top connection is outside down to be connected with isocon top, the isocon bottom connects with dividing fluid top major thread, the feed tube bottom connects with dividing fluid top minor thread, divide the fluid bottom to connect with leather cup joint top, leather cup joint bottom connects with crossover sub top, suit leather cup on the leather cup joint, crossover sub bottom minor thread connects with central tube top, crossover sub bottom major thread connects with outer tube top, between central tube and the outer tube flight is arranged, umbrella crown is arranged under the flight.
The beneficial effects of the utility model are: before well liquid flows to oil well pump, well liquid is through the spiral separation parts and divide fluidic component, utilize gravitational difference and slippage effect between gas, sand, liquid to realize the spiral between liquid, gas, sand and dual efficient separation of gravity, reduce the gas and the sand grains that enter oil well pump, improve the pump efficiency of oil well pump, reduce or eliminate the infringement of sand grains, can prolong the production cycle property of oil well, improve the oil well economic benefit oil well pump.
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.
By top connection 1, feed tube 3, isocon 4, divide fluid 5, leather cup joint 6, leather cup 7, crossover sub 8, central tube 9, flight 10, umbrella crown 11, outer tube 12, lower contact 13 is formed, 1 time inside of top connection connects with feed tube 3 tops, 1 time outside of top connection connects with isocon 4 tops, isocon 4 bottoms connect with dividing fluid 5 top major threads, feed tube 3 bottoms connect with dividing fluid 5 top minor threads, divide fluid 5 bottoms to connect with leather cup joint 6 tops, leather cup joint 6 bottoms connect with crossover sub 8 tops, suit leather cup 7 on the leather cup joint 6, crossover sub 8 bottom minor threads connect with central tube 9 tops, crossover sub 8 bottom major threads connect with outer tube 12 tops, between central tube 9 and the outer tube 12 flight 10 is arranged, umbrella crown 11 is arranged under the flight 10.On the central tube 9 at umbrella crown 11 positions linked hole is arranged, linked hole is arranged at outer tube 12 tops.Divide fluid 5 sides that linked hole is arranged.Top connection 1 has sealing ring 2 with feed tube 3 connection places.
Obstruction is arranged at central tube 9 bottoms, and well liquid can only enter in the central tube 9 from the linked hole on the central tube 9 of umbrella crown 11.
During the oil well pump oil pumping, well liquid enters from the linked hole on outer tube 12 tops, and through flight 10 and umbrella crown 11, the linked hole from the central tube 9 of umbrella crown 11 enters in the central tube 9.At this moment, the bubble in the well liquid upwards is discharged in the sleeve pipe after separated by the effect of spiral centrifugal force and gravity, and sand grains sinks to and realizes first separation under the pump in the tail pipe under centrifugal force and action of gravity.Well liquid from central tube 9, divide fluid 6, feed tube 3 around to the oil jacket annular space, enter from minute fluid 6 side linked holes and be up in the pump.In the cyclic process of well liquid in isocon 4, because the effect of gravity and slippage effect, gas is up to be discharged in the oil jacket annular space, and sand grains is descending to be deposited in the oil well pocket, has finished the secondary separation of gas sand.
