摘要
In the ways of recovering eroding strata’s thickness, the problem of extra-compensation and less-compensation of eroding strata is the essential factor that always restricts the selection of the ways and the result that is whether right or not. Example for Dongpu Depression, the rationality of recovering the Dongying Formation thickness by the method of mudstone compaction is analyzed. By this, the new cognition for compensation sediment of eroding strata is acquired. The study shows that when using the method of recovering eroding strata’s thickness that relates to the tendency of the pore’s variation with depth, the compensation sediment of eroding strata should be understood by weight compensation. When using the method of recovering eroding strata’s thickness that relates to the temperature index, the compensation sediment of eroding strata should be understood by temperature compensation. And it shouldn’t be understood by thickness compensation simply.
