For an oil field that are during petroleum development and some relative logging data are available in the field area, a new method of using seismic attribute constraint and logging interpolation between wells can be applied to predict the plane distribution of dolomite volume (,) in the reservoir. It includes three steps: (1) Using the multi-mineral model logging interpretation technique to calculate the volume percentage of dolomite in a single well; (2) Analyzing the relativity of seismic attribute with dolomite V(,) curve from logging calculation to find out the best relevant attribute; (3) Using the "Convergent" interpolation method in the PETREL software to interpolate the volume percentage of dolomite between wells under the constraint of the chosen seismic attribute. The application of this method shows good results at Area C in northeastern Sichuan Basin. An accurate calculation of volume percentage of dolomite in a single well and the choice of the best relevant seismic attribute are the two key factors for this method.
