Abstract: The diverting performance influence factors in temperature, permeability multiple, acid formula and the injection flow rate of the self-diverting acid with double-core flow test are studied. The experimental results show that the diverting range and diverting extent decrease with increasing of the temperature and permeability multiple, and will improve with increasing of the adding amount of diverting agent. The different injection flow rate also affects the diverting performance, when the flow rate is low, the flow rate increasing is beneficial to improve the diverting effect, on the contrary, if the flow rate is too high, it will be disadvantageous to the diverting performance.
