Description
Technical field
The invention belongs to oil extraction in oil field technical field, and in particular to a kind of automatic limiting flow pattern eddy flow water control valve.
Background technology
Developed at present for horizontal well with bottom water reservoir, especially long well section horizontal well, due to pit shaft frictional resistance and unbalanced pressure
The influence of difference, horizontal segment both ends fluid producing intensity is high, and middle fluid producing intensity is low, causes the contribution rate of each section of horizontal well very uneven
Weighing apparatus, with the passage of mining time, the funneling effect of horizontal well is further obvious, and at horizontal segment beginning, barometric gradient maximum is formed
Water ridge, causes bottom water coning；Meanwhile for heterogeneous, multilayered reservoir, since interlayer contradiction protrudes, can more aggravate bottom water or
Pneumatic jack coning, makes the advantage of horizontal well can not give full play to, and causes the wasting of resources and fund to waste.
One of technical cue of Oil Field is to add current-limiting apparatus on the completion tubular column of horizontal well to cut open with equilibrium production liquid
Face, delays bottom water coning.But current-limiting apparatus is to break face by way of increasing and flowing parasitic pressure drop to adjust production liquid, it not only increases
The big flow pressure drop of water, also increases the flow pressure drop of oil.And the position of high yield water is often Thief zone in the earth formation, and
The position of high oil-producing, so tripping in current-limiting apparatus can reduce live crude oil yield.
Therefore, design one kind is according to fluid properties automatic identification fluid, and guides different fluid to flow through different runners, produces
The valve of raw different flow pressure drop has great importance, this, which will strengthen bottom water reservoir, reduces moisture content, increases crude output
Effect, greatly improves the exploitation benefit in oil field.
Utility model content
The purpose of the utility model is to overcome the shortcomings that the prior art, solve current-limiting apparatus not only controlled water in high permeability zone but also
The problem of oil-control, there is provided one kind can automatically select flow channel according to fluid properties, the output of bottom water be controlled, suitable for oil field bottom
Horizontal well eddy flow water control valve after water breakthrough.
The purpose of this utility model is achieved through the following technical solutions：Horizontal well eddy flow water control valve, it is characterised in that：It
Including two parts of upper end cover and bottom end cover.It is provided with inlet for interference fit, bottom end cover between upper end cover bottom end cover and is used for
Fluid flows into, and contour stealth runner, contour stealth baffle, inward eddy baffle are used for inducing fluid eddy flow, contour stealth baffle, inward eddy gear
Plate is provided with outer chute and interior chute flows to eddy flow runner and spin chamber for inducing fluid, and spin chamber is provided with communicating valve
With exterior nozzle.
It can increase eddy flow baffle plate between the contour stealth baffle of the valve body lower end lid, inward eddy baffle, accelerate big
In or equal to 1.
The valve body lower end lid is provided with one or more inlets.
The utility model has the following advantages：
The utility model relies only on the property of fluid, and fluid is shunted automatically, on the premise of unlimited liquefaction output,
The output of water is controlled, considerably increases the yield and recovery ratio in oil field.
The utility model does not have moving component, substantially reduces the damage probability of valve, enhances the reliable of valve working
Property, performance has far better than other control water conservancy projects.

Embodiment
Below in conjunction with the accompanying drawings and the various states of device are further described the utility model, the guarantor of the utility model
Shield scope is not limited to as described below：
As shown in Figure 1, New-type Swirl Flow water control valve includes 2 two parts of upper end cover 1 and bottom end cover.
As shown in Figure 2, Figure 3, Figure 4, bottom end cover 2 is provided with the contour stealth runner 4 that inlet 3 is connected with inlet 3, and
Contour stealth baffle 5, inward eddy baffle 6, contour stealth baffle 5 are provided with outer chute 7, and inward eddy baffle 6 is provided with interior chute 8, outside
Eddy flow baffle plate 5 and inward eddy baffle 6 define inward eddy runner 9, and inward eddy baffle 6 defines spin chamber 10, spin chamber
10 bottom is provided with outlet nozzle 11, and nozzle 11 runs through bottom end cover 2, connects the exterior space of the lower part of bottom end cover 2.
As shown in Figure 1, upper end cover 1 is overlying on the top of bottom end cover 2, and good seal between upper end cover 1 and bottom end cover 2, on
End cap 1 and bottom end cover 2 are using interference fit so that fluid can only enter valve by inlet 3, can only be flowed out by nozzle 11
Valve.Upper end cover 1 and 2 both sides contact position of bottom end cover, which use, to be welded to connect.
The course of work of the utility model is as follows：Reservoir fluid is flowed into from pit shaft by inlet 3, if the fluid flowed into is
The higher crude oil of viscosity, under the action of viscous force, fluid flows into inward eddy runner 9 by outer chute 7, then passes through interior stream again
Groove 8 flows into spin chamber 10, is most flowed out afterwards after the throttling of nozzle 11, fluid is in contour stealth runner 4, inward eddy runner 9, eddy flow
Without too big rotation in chamber 10, the pressure drop of generation is small, the output of unlimited liquefaction；If the low water of the fluid such as viscosity flowed into, used
Property power and centrifugal force under the action of, fluid can rotate in contour stealth runner 4, by outer chute 7 flow into inward eddy runner 9 it is follow-up
Continuous rotation, then flows into spin chamber 10 by interior chute 8 and continues to rotate, and finally flows out, flows after the throttling of nozzle 11 again
Body multiple rotary in contour stealth runner 4, inward eddy runner 9, spin chamber 10, forms high flow rate, produces high pressure drop.Therefore,
The resistance that crude oil flows through is much smaller than the resistance of current overwinding flow control water valve, so as to fulfill the output of limitation water.
