PetroChina has obtained a patent for a fracturing system liquid addition device, which can achieve uniform addition of liquid additives.

financial sector on March 17, 2025, information from the State Intellectual Property Office shows that China National Petroleum Corporation has obtained a patent called "a fracturing system liquid adding device", authorized announcement number CN 222615320 U, and the application date It is April 2024.

patent abstract shows, a fracturing system liquid adding device. The utility model includes a liquid additive tank and a sand mixing equipment. A cam rotor pump and a mass flow meter are sequentially installed between the liquid inlet end and the liquid outlet end of the additive delivery pipeline. The cam rotor pump is driven by an integrated frequency conversion motor; The flow meter is connected with the control system; the mass flow meter and the integrated frequency conversion motor are connected with the control system, and the control system adjusts the flow rate and flow rate of the liquid additive by controlling the integrated frequency conversion motor. The beneficial effect is that the structure design is reasonable, the uniform addition of liquid additives can be realized, and the addition accuracy is improved. At the same time, it has the characteristics of small size and simple operation; the device can accurately deliver the liquid additives to the mixing tank of the sand mixing equipment, and The fracturing fluid is evenly mixed; multiple sets of adding devices can be set as required to deliver different liquid additives to meet the requirements of the fracturing operation process.
