Experimental device and method for determining blockage type and main control factor of polymer injection well

An experimental device for determining a blockage type and a main control factor of a polymer injection well, comprising an injection system, a simulation system, an output collection system, and an information acquisition system;

• wherein
• the injection system is configured to inject a fluid into the simulation system;
• the injection system includes a fluid container;
• the fluid container includes a fluid outlet, the fluid outlet is connected with one end of a fluid injection pipe, and the at least one core sample tube is connected with the other end of the fluid injection pipe;
• the fluid injection pipe is provided with a control value configured to control the fluid to be injected into the at least one core sample tube;
• the simulation system is configured to perform a simulation experiment, and the simulation system includes the at least one core sample tube;
• the output collection system is configured to collect the fluid discharged from the simulation system;
• the fluid collection container includes a fluid collection container, the fluid collection container includes a plurality of sub-containers, one of the sub-containers is connected with one of the at least one core sample tube through a fluid collection pipe;
• and
• the information acquisition system is configured to acquire an experimental sample parameter of the at least one core sample tube during the simulation experiment;
• wherein
• the simulation system further includes a remote processor, and the remote processor is configured to:
• determine a valve parameter corresponding to the control valve on the fluid injection pipe based on an initial sample parameter corresponding to the at least one core sample tube, and a container parameter corresponding to each of the plurality of sub-containers, the valve parameter being used to regulate opening and closing of the control valve.
