Well-to-earthquake combined type repeated stratum identification method

The embodiment of the invention provides a well-to-earthquake combined type repeated stratum identification method. The method comprises the following steps: determining a fault position according tolithologic data of a well-completed rock stratum; determining a hanging wall and a heading wall of the fault on a seismic profile map according to the fault position, and judging whether the fault isa repeated stratum or not according to lithological data of the hanging wall and the heading wall of the fault to obtain a first judgment result; according to a gamma curve graph, determining the gyratory characteristics of the hanging wall and the heading wall of the fault, and according to the gyratory characteristics of the hanging wall and the heading wall of the fault, judging whether the fault is a repeated stratum or not to obtain a second judgment result; and according to the first judgment result and the second judgment result, determining whether the fault is a repeated stratum or not. Therefore, problems tha
