The invention belongs to the technical field of oil absorption value detection, and particularly relates to a silicon dioxide oil absorption value measuring method which comprises the following steps: 1) measuring the apparent density and pore volume of a typical silicon dioxide sample; 2) measuring the oil absorption value of the typical silicon dioxide sample by using a manual method; 3) fitting k and phi values according to the apparent density, pore volume and oil absorption value formula of the typical silicon dioxide sample to obtain a calculation formula of the silicon dioxide oil absorption value; and 4) measuring the apparent density and pore volume of a to-be-measured silicon dioxide sample, and calculating the oil absorption value of the to-be-measured silicon dioxide sample according to the calculation formula of the silicon dioxide oil absorption value. By means of the measuring method, manufacturers, clients and other parties can conveniently conduct unified measuring, the product quality can be
