This application discloses a method, apparatus, equipment, medium, and product for shale gas platform site selection based on seismic risk assessment, relating to the field of platform site selection. The method includes: obtaining the fault hazard of a grid based on the shear stress and normal stress of triangular facet elements; inverting the stress field based on focal mechanism data to obtain the in-situ stress field of the triangular facet elements; clustering the maximum principal stress directions of the triangular facet elements and updating the maximum principal stress directions based on the cluster centers to obtain the maximum principal stress directions of the grid; interpolating the in-situ stress fields of the triangular facet elements to obtain the in-situ stress field of the grid; obtaining the seismic susceptibility of the grid based on factors such as the grid's historical seismic activity, fault hazard, in-situ stress field, historical earthquake frequency, historical earthquake energy, and maximum principal stress direction; and determining the optimal well placement location based on the grid's seismic susceptibility, fault hazard, and maximum principal stress direction. This application improves the rationality of shale gas platform site selection.

The utility model relates to the technical field of building shock insulation, and discloses a stiffened ring lead core steel pipe shock insulation support, which comprises a steel pipe, the upper and lower ends of the steel pipe are fixedly connected with connecting steel plates, the top end of the connecting steel plate on the lower side is fixedly connected with two support plates one, the top end of each of the two support plates one is fixedly connected with two support rods, the outer side of each of the two support rods is slidably connected with a connecting block, a screw rod is threadedly connected in the connecting block, a small bolt is threadedly connected to the outer side of the screw rod, the top end of the connecting block is fixedly connected with two fixed columns, and the top end of each of the two fixed columns is fixedly connected with a connecting ring. In the utility model, the ground beam, the support plate and the damper and other components work together to realize shock resistance and buffering, the damper is deformed to store energy and then releases the energy under the action of earthquake vibration, pushes the support plate to reset, the sliding column is prevented from being deviated, can absorb earthquake energy, provides auxiliary support for the device, reduces structural response, and improves the seismic safety of the building.
