One, technical field
The utility model relates in the oil exploitation, and downhole tool or completion mode be to the testing shear performance equipment of injection of polymer, particularly a kind of polymer testing shear performance device.
Two, background technology
In the oil exploitation, have much for poly-instrument of down-hole notes and different completion mode on earth for the injection of polymer Effect on Performance? which kind of annotates polymerizing technology, downhole tool or completion mode to injection of polymer adverse effect minimum? existing a kind of employing cuts a small pieces sand screen sample, carry out the qualitative laboratory test of microtomy, this test method is because sample is little, polymer fluid flow-control difficulty is big, anti-interference is poor, the test result error is also big, simultaneously, this method can not satisfy the performance test of instruments such as farm labourer's tool such as polymer injection allocation device.
Three, summary of the invention
Order of the present utility model provides a kind of polymer testing shear performance device, adopts the combining structure of seal operation tube and test instrument, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Polymer testing shear performance device described in the utility model comprises low control valve, flow meter, inlet sample valve, inlet pressure table, sealing drum, test instrument, delivery gauge, outlet sample valve, seal nipple, the sampling short circuit sheared.Described sealing drum is connected with seal nipple, seal nipple is connected with test instrument with the sampling short circuit respectively, sampling short circuit upper end is installed in turn and is connected with inlet pressure table, inlet sample valve, flow meter and the low control valve of shearing, the sealing drum bottom is equipped with delivery gauge and outlet sample valve in turn, and the sealing drum lower end is provided with outlet opening.
Wherein, described test instrument upper end is connected with seal nipple, and remainder is in the sealing drum.Described seal nipple upper end is connected with the sampling short circuit, and the lower end is connected with test instrument.
The utility model has following advantage compared with prior art:
1, can cross parameters such as the sticking damage of mechanical degradation annotated behind the poly-instrument, pressure drop to polymer and carry out test and evaluation, simple to operate, test data accurately and reliably;
2, adopt the low low shearing booster pump of shearing control valve, variable frequency control to make experiment process control to minimum to the undesirable element of polymer.
Four, description of drawings
Fig. 1 is a kind of example structure schematic diagram of the present utility model
Fig. 2 is for pressing A shown in Figure 1 to local structure for amplifying schematic diagram
Five, the specific embodiment
Consult accompanying drawing, a kind of polymer testing shear performance device comprises low control valve 1, flow meter 2, inlet sample valve 3, inlet pressure table 4, sealing drum 5, test instrument 6, delivery gauge 7, outlet sample valve 8, seal nipple 9, the sampling short circuit 10 sheared.Sealing drum 5 is connected with seal nipple 9, seal nipple 9 is connected with test instrument 6 with sampling short circuit 10 respectively, sampling short circuit 10 upper ends are installed in turn and are connected with inlet pressure table 4, inlet sample valve 3, flow meter 2 and the low control valve 1 of shearing, sealing drum 5 bottoms are equipped with delivery gauge 7 and outlet sample valve 8 in turn, and sealing drum 5 lower ends are provided with outlet opening.
During the test of polymer viscosity loss late, with the polymer for preparing, after the booster pump supercharging that has variable frequency control, be adjusted to certain flow by the low control valve 1 of shearing again, allow polymer solution under constant speed, flow into test instrument 6 through sampling short circuit 10, flow to again in the seal operation tube 5, by measuring the viscosity of polymer by test instrument 6 front and back, it is the polymer viscosity that get in test access sample valve 3 and outlet sample valve 8 places, calculate the viscosity loss rate of polymer, thereby determine the mechanical shearing palliating degradation degree of tested instrument polymer.
During pressure fall-off test,, directly calculate the pressure reduction result of polymer by quilt test instrument by the numerical value of inlet pressure table 4 with delivery gauge 7.
