Abstract

Embodiments of the present disclosure provide an experimental device and a method for determining a blockage type and a main control factor of a polymer injection well. The experimental device includes an injection system, a simulation system, an output collection system, and an information acquisition system. The simulation system includes a remote processor. The method comprises: obtaining a process parameter of the polymer injection well during actual construction, and a reservoir parameter corresponding to the polymer injection well; configuring the experimental device according to the process parameter and the reservoir parameter; conducting at least one of water injection development simulation, polymer injection development simulation, regulation and displacement operation simulation, and comprehensive operation simulation based on the experimental device according to the process parameter to obtain simulation data; and determining the blockage type and the main control factor of the polymer injection well based on the simulation data.
