STUDY ON BURIAL HISTORY OF THE STRATA IN JIANGHAN BASIN

The compaction model suitable for Jianghan Basin was established, and different compactive correcting formala were chosen for different types of rocks. Furthermore, the erosional thickness of the strata in the end of late Tertiary was restored with the conversional relation of acoustic time and porosity. Using the method of "backstripping", compactive restoration was progressively made for the strata in each well, and charts respective for plane development, variations in thickness and burial history were also complished. The large amonnt of computation and charting work for the study were done by computer.
