Abstract
In a fracturing control apparatus, a first chemical agent storage tank is connected with a first delivery pump, and a material outlet of the first delivery pump communicates with a first position of a first fracturing fluid conveying pipeline. An outlet of the first fracturing fluid conveying pipeline communicates with an inlet of a fracturing pump, an outlet of the fracturing pump communicates with an inlet of a second fracturing fluid conveying pipeline, and a first flow detector is arranged at a second position of the second fracturing fluid conveying pipeline. The first delivery pump is connected with a first output interface of a controller, and the first flow detector is connected with a first input interface of the controller. The fracturing control apparatus and the control method of the fracturing control apparatus are used for adding chemical agents into fracturing fluids.
