Stratum pinching-out line prediction method based on geology-earthquake combination

The invention relates to a stratum pinchout line prediction method based on geology-earthquake combination. The method comprises the following steps: collecting data; according to the logging electrical curve and the rock core, selecting a lithology-electrical marker bed, establishing a lithology-electrical relationship, and determining development characteristics and interface identification marks; establishing a regional well-connecting profile, determining a sequence stratigraphic distribution rule, and constructing a stratigraphic transverse change geological mode; based on the three-dimensional earthquake work area, drawing a section stratum pinching trend line in combination with the area well connection section; adopting a stratum thickness method to refine the position of the pinching line and determine the geological characteristics of the stratum pinching line; calculating the included angle of the pinch-out trend line at the pinch-out point and the average value of the included angle by using the s
