In order to study the control factors and mechanism of oolitic limestone reservoir corrosion by organic acid produced in burial stage. The reactions of acetic acid (initial 0. 1 mol/L) with oolitic limestone were investigated using the rotating-disk corrosion reactor system (CRS). The results indicate that dissolution rates of dolomitic oolite limestone are between 3. 26×10^–7 and 6. 66×10^–7 mol/(cm². s), and dissolution rates increase as temperature or disk rotation speed increasing. In summary, dissolution and alteration of Feixianguan Formation by organic acid fluids under burial condition should not be neglected during the process of the secondary pore formation.
