Fine stratigraphic correlation and its application in complicated formation-a case study of Gasi N_1-N_2~1 reservoir

Aimed at a series of difficulties about stratigraphic correlation in complicated formation,a method of correlation is proposed,which puts the stresses on the using of the data from seismic horizon,logging and dynamic performance. Good effects have been achieved in the application of this method for the fine stratigraphic classification.This method utilizes the advantages from logging data in the vertical seismic data in the horizontal direction to carry out the recognition and correlation of sand,also considered sedimentary environment and combined with 3D view technology,timely analyzing the result of stratigraphic correlation.The method of fine stratigraphic correlation for complicated formation is also fit for other oilfields with the same kind.
