Description

technical field [0001] The invention belongs to the technical field of oil field control and flooding, and in particular relates to a high-power harmonic wave-chemical composite control and drive device and a control and drive method. Background technique [0002] High-power harmonic wave oil recovery and chemical control and flooding are oil recovery technologies for improving secondary and tertiary oil recovery. High-power harmonic wave oil recovery uses the propagation of acoustic physical fields to directly or indirectly act on the formation with strong vibration energy, causing physical and chemical changes in the oil layer and fluid, thereby improving the seepage conditions of the oil layer and achieving the purpose of increasing production and injection of oil and water wells Physical oil recovery technology. The chemical control and flooding technology utilizes the injection of chemicals into the injection well to block the channeling of underground reservoirs and i...
