Division and correlation of sandstone reservoirs in the Linpan oil field,Jiyang depression,Shandong

Division and correlation of sandstone reservoirs are most fundamental and important work in the oil field development.The division and correlation of the sandstone reservoirs in the Linpan oil field,Jiyang depression are based on the study of the main oil reservoirs from the third member to the lower part of the second member of the Shahejie Formation,with the emphasis on the principles and methods,isochronous correlation of the high-resolution sequence stratigraphy,and presentation of four models for sandstone correlation.The results of research may be helpful to the reservoir description,construction of high-precision reservoir models,and improvement of recovery efficiency.
