Description

technical field [0001] The invention belongs to the technical field of fracturing construction mechanization and automation, and in particular relates to a fully automatic liquid adding device and an adding calibration method for fracturing construction. Background technique [0002] Water-based fracturing fluid is currently the subject of domestic oil and gas field stimulation and reconstruction fracturing fluid. The main function of fracturing fluid is to carry sand and create fractures. It is not only one of the key factors determining the success or failure of fracturing construction, but also the guarantee of the effectiveness of fracturing stimulation. . At present, when continuously mixing liquid in the dense gas area, various aqua materials are mixed according to the designed ratio and poured into the aqua material pool, and the liquid adding pump of the mixing vehicle is pumped according to the total ratio. This addition method is due to traditional metering. The d...
