Embodiment 1
[0091] This embodiment provides a kind of ICD testing device (such as figure 1 As shown, it is a subsystem of the test system):
[0092] Wherein, the device includes: a constant temperature box 11 , a closed box body 12 placed in the constant temperature box, and a flow meter 13 .
[0093] Described casing 12 comprises inlet 121 and outlet 122, and the inlet end in casing is provided with sand control structural unit 14, and the outlet end in casing is provided with ICD interface 15; The inlet 121 is connected with the outlet 122 of the box and the inlet 131 of the flowmeter by the outlet pipeline 17 of the box, and the outlet 132 of the flowmeter is connected with the outlet pipeline 18 of the flowmeter.
[0094] The device also includes two first differential pressure measuring branches 19 for measuring the pressure difference between the tank and the outlet pipeline of the flowmeter, and two for measuring the inlet pipeline of the tank and the outlet pipeline of the flowme...
Embodiment 2
[0100] This embodiment provides a kind of ICD testing system (such as figure 2 shown):
[0101] Wherein, the device includes: an output fluid supply device 32 and four groups of ICD testing units 31 ( figure 2 Only one group of ICD test unit structures are marked in the above, and the other three groups are the same).
[0102] The ICD test unit includes an ICD test device 311 as described in Embodiment 1, a fluid well simulation device 312 (coil pipe) for simulating fluid flow conditions in the well, a first valve 313 (back pressure), and a first valve 313 (back pressure) connected in series through pipelines. valve), temperature regulating device 314 (heat exchanger), production fluid collection tank 315, second valve 316 and third valve 317, wherein the second valve 316 is set in parallel with the first valve 313.
[0103] The production fluid supply device 32 includes a mortar supply device 325 , a gas supply device 324 , an oil supply device 323 , a steam supply device...
Embodiment 3
[0107] The present embodiment provides the method utilizing the system of embodiment 2 to carry out ICD test:
[0108] 1.1 preparation
[0109] a) Before the experiment, make sure that all the valves of the process are closed; the water tank is fully stored; the data collection of all sensors is normal, and the automatic execution program is running normally.
[0110] b) The steam generator is set at the predetermined temperature of the experimental plan; the temperature of the heating pipeline along the experimental process is set 2-5°C higher than the temperature of the experimental plan;
[0111] c) According to the experimental plan, select four groups of ICD test units and connect them to the process in parallel. Put the ICD to be tested into the ICD test device and connect it to the ICD interface, set up the sand control unit (implant the sand control structure into the sand control unit), seal the ICD test device, and set the thermostat according to the temperature of ...
