Description
Technical field
This utility model is related to a kind of oil-field flooding gas stripping type deoxidation tower of oil-field flooding.
Background technology
During oil exploitation, low permeability oil field is the recovery ratio for improving oil generally using the method for water filling.Its
The water source of injection can be recovered water, stratum water or surface water etc..If containing various dissolved gas, wherein oxygen in these water
Presence accelerates the corrosion of metallic conduit and equipment, and research finds the filling pipe of the high oxygenated water of conveying after 10 years use, just
Needs are re-replaced.Equilibrium concentration of the oxygen in water is directly proportional with the partial pressure of oxygen in the gas phase being in contact with it, due to air stripping
Almost anaerobic in gas, air stripping process destroy original vapor liquid equilibrium, therefore oxygen can be made from water desorbing to be stripped gas and take away.Cause
This, reduces operating pressure, the oxygen content reduced in gas stripping gas, improves the efficiency that temperature etc. can improve air- extraction deoxidation.Gas
Lifting manipulation deoxidation utilizes natural gas or N2Deng the noble gases immiscible with sea water and contact with sea water, reduce and contact with sea water
The partial pressure of oxygen in gas, so that oxygen parses and be stripped the deoxidization technique that gas is taken away from sea water.At present, air stripping
Be used widely abroad by each major oil and gas field for method deoxidization technique.
The content of the invention
This utility model purpose is for the oxygen removal efficiency that water is injected during improving oil-field flooding, there is provided a kind of oil field
Water filling gas stripping type deoxidation tower, it is convenient to use, can not only can also go out other corrosive gas except deoxidation.
The technical scheme adopted by this utility model is：
A kind of this utility model oil-field flooding gas stripping type deoxidation tower, is mainly gone out by water inlet, C-shaped baffle plate, tower body, gas
Mouth, the sealing of inertia packed layer, plastic hoop, sealed bottom support net, gas access, manhole, water-stored section, vortex breaker and outlet group
Into.The water inlet is located at the left side of tower body, and, located at the left side of tower body, outlet is located at tower body for gas outlet and gas access
Bottom, lower position of the manhole located at gas access are opened manhole in maintenance and are keeped in repair；Vortex breaker is located at the bottom of tower body
It is connected with outlet, for preventing the generation of whirlpool.C-shaped baffle plate is respectively arranged on water inlet and gas porch, and with which apart
There is a certain distance, the fluid and the gas entered from gas access entered from water inlet is carried out after C-shaped baffle plate for the first time
Evenly distribute；The gas entered from gas access is nitrogen, and using two-layer design, its each layer of top is inertia for plastic hoop sealing
Packed layer, bottom are sealed bottom support net.It is transition zone between the ground floor and the second layer of plastic hoop sealing, for gas stripping gas
It is fully contacted with the fluid entered from porch again when rising.
Advantage of the present utility model：Convenient to use, the effect of deoxidation is good, the oxygen contained during fluid can not only be removed and
And other corrosive gas can also be removed.
Description of the drawings
Fig. 1 is a kind of structural representation of oil-field flooding gas stripping type deoxidation tower of this utility model.
In figure：1. water inlet, 2.C shape baffle plates, 3. tower body, 4. gas outlet, 5. inertia packed layer, 6. plastic hoop sealing,
7. sealed bottom support net, 8. gas access, 9. manhole, 10. water-stored section, 11. vortex breakers, 12. outlets.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further.
As shown in figure 1, a kind of this utility model oil-field flooding gas stripping type deoxidation tower, mainly by water inlet 1, C-shaped baffle plate
2nd, tower body 3, gas outlet 4, the sealing 6, sealed bottom support net 7, gas access 8 of inertia packed layer 5, plastic hoop, manhole 9, water storage
Section 10, vortex breaker 11 and outlet 12 are constituted.The water inlet 1 is set located at the left side of tower body 3, gas outlet 4 and gas access 8
In the left side of tower body 3, outlet 12 is located at the bottom of tower body 3, lower position of the manhole 9 located at gas access 8；Vortex breaker 11
It is connected with outlet 12 in the bottom of tower body 3, C-shaped baffle plate 2 is respectively arranged at water inlet 1 and gas access 8, and is apart had with which
A certain distance；The gas entered from gas access 8 is nitrogen, and using two-layer design, its each layer of top is for plastic hoop sealing 6
Inertia packed layer 5, bottom are sealed bottom support net 7, are transition zone between the ground floor and the second layer of plastic hoop sealing 6.
As shown in figure 1, when fluid enters tower body 3 from water inlet 1, mutually clashing into C-shaped baffle plate 2 first, clashing into latter portion
, from C-shaped baffle plate upper flow, another part is from C-shaped baffle plate lower flow, equal after fluid flows through inertia packed layer 5 for shunting body
It is even be distributed in tower body 3 after flow to plastic hoop sealing 6, plastic hoop sealing 6 in contacted with nitrogen, now the oxygen in fluid is big
Part is departed from, by sealed bottom support net 7 toward downstream to relief area after ground floor plastic hoop sealing 6 is flow through；By second
Layer plastic hoop seal 6 tops inertia packed layer 5 after, the fluid for having removed oxygen and do not remove oxygen fluid in second layer plastics
Ring is sealed and is sufficiently mixed in the inertia packed layer 5 on 6 tops.Fluid after being sufficiently mixed is sealed by second layer plastic hoop
6, and second deoxidation is carried out with the nitrogen entered from gas access 8 in plastic hoop sealing 6.The fluid for being stripped of oxygen is down transported
It is dynamic, and water-stored section 10 is flow to, by flowing out tower body 3 from outlet 12 after vortex breaker 11.
