| Zusammenfassung: | The invention belongs to the technical field of exploration and development of oil and gas reservoirs, and discloses a quantitative evaluation method for strike-slip fracture activity intensity, which comprises the following steps of: carrying out fine structure interpretation based on high-precision three-dimensional seismic data, and obtaining a plane distribution range of a strike-slip fracture fracture zone by utilizing fine calibration of a drilled well on this basis; further obtaining transverse deformation width and vertical deformation height difference data capable of representing the strike-slip fracture deformation degree, further obtaining an activity intensity coefficient capable of representing the strike-slip fracture activity intensity, and finally quantitatively representing the strike-slip fracture activity intensity by using the activity intensity coefficient. An operable quantitative evaluation index is provided for quantitative evaluation of the activity intensity of the strike-slip fault |
