| Abstract: | This paper presents a method for predicting CaCO3 scaling in oilfield water based on the calculation of deposition-dissolution equilibrium. The calculation methods for critical concentration and critical steady constant are proposed. The criteria for selecting the inhibitors are given. Calculations are made on the data both from literatures and observations at the oilfields. The satisfactory results are obtained. |
