The invention discloses a chemical agent solution quick preparation device and method. The device comprises a liquid dispensing tank, a driving device, and a negative pressure jet suction device; thenegative pressure jet suction device comprises a spray pipe, a suction pipe and a venturi connected in sequence; the left end of the spray pipe is a liquid inlet, and the right end forms a conical tubular nozzle; the nozzle passes through a central cavity of the suction pipe and directly extends into a mixed liquid inlet at a left end of the venturi; a right end of the venturi is a mixed liquid outlet; a vacuum suction chamber is formed between the outer wall of the nozzle and the inner wall of the suction pipe; the outer wall of the left end of the suction pipe opens a radial material suctioninlet that is connected with the vacuum suction chamber; the liquid inlet is connected to the outlet of the driving device, the material suction inlet is connected to a feeding pipeline, and the mixed liquid outlet is connected to the liquid preparation inlet opened at the upper end of the liquid preparation tank. The invention solves the problems that the traditional liquid preparation control method has the disadvantages of poor quality of the existing liquid preparation, slow liquid preparation speed and complicated process flow.
Description
technical field [0001] The invention relates to the liquid preparation technology of oil production chemical agents in oilfields, in particular to a chemical agent solution rapid preparation device and method. Background technique [0002] In the field of tertiary oil recovery in the late stage of oilfield exploitation, technologies such as water plugging and profile control, profile control and flooding, chemical flooding, and polymer flooding are generally adopted to improve oil recovery. In these technologies, the uniform dispersion, dissolution and rapid preparation of the chemical agents used are the key links to ensure the quality of the process. [0003] The traditional liquid mixing tank includes a tank body and a mechanical stirring system. The mechanical stirring system is usually equipped with an agitator above the tank body. The agitator is composed of a motor, a reduction gearbox, a gear set, a stirring shaft, etc., and is connected to the reduction gearbox thro...
