Embodiment Construction
[0067] In order to make the above and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments are listed below and shown in the accompanying drawings in detail as follows.
[0068] like figure 1 as shown, figure 1 It is a flow chart of the rock porosity recovery method in superimposed basin oil and gas accumulation period of the present invention.
[0069] Step 101, recovery of stratum denudation amount
[0070] Due to the impact of tectonic movement, the formation will be denuded during the uplift process, so the denudation amount of the strata needs to be restored. Using the acoustic wave transit time curve, select the acoustic wave transit time curve corresponding to the mudstone section with a thickness of not less than 1.5m for curve fitting, restore the erosion amount, and then restore the erosion amount of the formation in different geological historical periods;
[0071] Wherein, the concrete steps of step 101 a...
