Problems solved by technology
[0003] It can be seen that the existing control technology cannot adapt to the control requirements of the new heterogeneous polymer dispersion and dissolution device in the process of controlling the heterogeneous polymer dispersion and dissolution device. For the problem of low process control accuracy, the degree of automation of the control system needs to be improved, and the level of informatization and intelligence of the control system needs to be improved to meet the current unattended requirements of the injection station.

Description
technical field [0001] The invention relates to the technical field of heterogeneous dispersion and dissolution device control, in particular to a control system and a control method for a heterogeneous polymer dispersion and dissolution device. Background technique [0002] With the continuous popularization and application of three-recovery polymer flooding technology, the remaining movable oil in the reservoir after polymer flooding still reaches 50%. In order to further improve the recovery rate of the reservoir after polymer flooding, B- The heterogeneous composite flooding system formula of PPG (Branched-Preformed Particle Gel, branched pre-crosslinked gel particles), polymer and surfactant. Specifically, conventional polymer dispersing and dissolving devices are currently used to prepare polymer mother liquor and PPG mother liquor respectively, and carry out aging, feeding, and injection respectively, and then mix and dilute with produced water and pour them into poly...
