Abstract
The present invention provides a stratigraphic correlation method and apparatus based on uncertainty. The stratigraphic correlation method comprises: determining a plurality of possible correlation positions in a well with uncertain layered position in a profile, in a stratigraphic correlation process; assigning a qualitative or quantitative certainty value to the plurality of correlation positions; and storing and displaying the plurality of correlation positions and certainty values thereof as different layered solutions on the profile, respectively. By setting a plurality of position solutions for a layer in the present invention, all possibilities of the layered position judged by the geological personnel can be recorded as references for the subsequent correlation of other profiles, the closing of the whole layered solution, and the quality control.
