The precise restoration of stratigraphic burial history and ancient landforms is crucial for predicting oil and gas reservoirs and understanding their enrichment patterns.The accuracy of compaction correction is the key to constraining the precise restoration of stratigraphic burial history and ancient landforms.In order to improve the accuracy of compaction correction,based on the principle of rock skeleton invariance,differential method was applied to construct compaction correction techniques for different rock types.The compaction correction calculation was carried out using actual well data from the Carboniferous strata in the Zhuanghai area of Shengli Oilfield.The results show that the rock compaction rate of this group of mud is 2.02-2.23,the sandstone compaction rate is 1.58-1.63,and the limestone compaction rate is 1.41-1.48.The shallower the burial depth,the thicker the layer,the more developed the undercompaction effect,and the higher the content of sandstone and limestone,the lower the total compaction rate of the layer.
