Starting from establishing models from carbonate matrix acidizing and real-time monitoring, methods for the matrix acidizing real-time monitoring and evaluation are studied. The methods are to use the data of wellhead working pressure and displacement from field detection for calculating the dynamic changes of skin coefficient during acidizing so as to real-time monitor and control the quality of acidizing. The result of field application shows that the acidizing effect can be effectively evaluated by using the methods.
