Control unit.Fill out sand tube 10 can be horizontality as shown in Figure 1, and fill out sand tube 10 can also be in vertical or heeling condition, pressure
The quantity and ranks of strength sensor 9 are set can be adjusted according to experiment needs, to adapt to simulate objective reality condition.
In the present embodiment, the measurement apparatus of gravel filling compaction also include that back-up sand pump 11 and devil liquor recovery are processed
Device 12, back-up sand pump 11 is used to be filled into the load fluid 15 containing gravel 14 in the inner chamber of fill out sand tube 10, devil liquor recovery treatment
Device 12 is used to reclaim the liquid in the load fluid of the discharge of screen casing 13, and devil liquor recovery processing unit 12 is located at the lower section of screen casing 13.
Back-up sand pump 11 and devil liquor recovery processing unit 12 can be connected with the control unit, to improve the survey that the gravel fills compaction
Measure the automaticity of device.
In the present invention, the inner connection tube line 4 in piston 2 plays a part of Equilibrium filling pressure (because piston two ends are received
Dynamic balance will not produce displacement).As shown in Figure 2 when back-up sand is started, the pressure of load fluid 15 is P;Load fluid 15 is through pressure tappings
(i.e. the upper of force snesor 9 is compacted in Fig. 1) and inner connection tube line 4 flow to the two ends of piston 2.Due to piston upper and lower ends pressure, face
Product is equal, so two ends stress is equal, is F=PS (S is piston upper and lower ends face area), and piston 2 is in stress balance
State, it is understood that be piston " suspension " in load fluid.Stowing pressure is to displacement transducer 3 when can so avoid filling
Interference, in the process piston do not produce displacement, the not output signal of displacement transducer 3, sand is compacted under pressure.
After sand off, as shown in figure 3, the water in load fluid can fall with circulatory system leak-off, only remaining gravel is full of
Cavity, load fluid pressure energy disappears, and there is no stowing pressure, gravel will tend to natural loose condition (of surface) to the upper and lower ends of piston 2,
Compaction can also change.Originally the resilience under the elastic reaction of itself of gravel 14 compressed, and screen resilience is applied to work
On plug 2.Be transmitted on displacement transducer 3 for position after resilience by piston 2, and displacement transducer 3 starts to output signal to control list
Unit.So, the size of signal output and output signal is whether there is according to compacting force snesor 9, you can judge back-up sand leading edge and back-up sand
The compaction of pipe filling extent and sand.
The measuring method that a kind of gravel fills compaction is described below, the measuring method of gravel filling compaction is adopted
The measurement apparatus of compaction are filled with above-mentioned gravel, the measuring method of gravel filling compaction is adopted including following step
Suddenly:
The load fluid 15 containing gravel 14 is filled into step 1, the inner chamber by back-up sand pump 11 to fill out sand tube 10;
Step 2, the position for having filled control unit record piston 2 after the load fluid 15 are initial position, such as Fig. 2 institutes
Show;
Step 3, a position for piston 2 is recorded every one section of setting time, observe the control unit and feed back the data for
Information, until the position stabilization of piston 2, re-records the final position of piston 2, as shown in Figure 3;One section of setting time can be with 1S
~10S;
Step 4, closing gravel filling experiment device, the data that analysis is obtained.The initial position according to piston 2 and final
The size of the difference of position judges the compaction of gravel filling and actual verification.
Specifically, being installed in place compacting force snesor 9 and completing to test Lou before starting experiment, then set technological parameter.Examination
When testing beginning, during load fluid 15 pumped into the inner chamber of opaque fill out sand tube 10 by back-up sand pump 11.Load fluid 15 is flowed through successively to be filled out
Sandpipe 10 and screen casing 13.Screen casing 13 is a series of steel pipe for being machined with small through hole, when load fluid 15 flows through screen casing 13, sand meeting
It is gradually deposited inside it, and the liquid phase substance such as water meeting leak-off falls, into devil liquor recovery processing unit 12.Due to test parameters not
With (discharge capacity, pressure, sand ratio etc.), the inside filling extent of fill out sand tube 10 is different, and the compaction of sand is also different, will cause piston
2 displacement is also different, and piston displacement and gravel pack degree and the relation of sand compaction are set up by repeatedly measurement, from
And can be according to the displacement accurate measurement gravel pack degree of piston and sand compaction, as shown in Figures 1 to 6.Typically,
The displacement of piston 2 is bigger, then gravel pack degree and sand compaction are also better.
The above, specific embodiment only of the invention, it is impossible to the scope that its restriction invention is implemented, so it is equivalent
The displacement of component, or the equivalent variations made according to scope of patent protection of the present invention and modification, should all still fall within what this patent was covered
Category.In addition, between technical characteristic and technical characteristic in the present invention, between technical characteristic and technical scheme, technical scheme with
Can be used with independent assortment between technical scheme.
