The invention discloses a device for interpreting fractured reservoir prediction. By the device, the seismic wave nonlinear dynamics properties, such as redundant dictionaries and chaos, of a fractured reservoir are computed; and by adopting a high order accumulation processing technology, non-gaussian seismic signals of the fractured reservoir can be processed and computed, so that the density aggregation projection analysis of acquired seismic attributes representing the fractured reservoir can be realized. According to the device, a computer is used for assisting in the completion of the interpretation of the fractured reservoir, so that favorable reservoir prediction files are formed. The device has the advantages of high computational efficiency, objective and accurate fractured reservoir interpretation results, and the like; and by the device, the accuracy of the reservoir interpretation and the seismic interpretation efficiency can be effectively improved.

The invention relates to a rapid three-dimensional fault interpretation method based on horizontal navigation. The method includes the steps that (1), the fault enhancement interpretative processing is carried out on seismic data, and a seismic data volume fully highlighting fault information is obtained; (2), time slices of which the interest interval reflects the fault plane distribution characteristic are extracted from the seismic data volume, and the time slices serve as horizontal navigation slices for fault interpretation; (3), a fault is selected from the horizontal navigation slices; (4), a seismic section is extracted in the direction perpendicular to the fault strike, and the section of the fault is interpreted at the projection point of the section of the fault; (5), meshing processing is carried out on a navigation plane interpretation result of the selected fault and an interpretation result of the fault of the extracted seismic section, and the results are projected to a newly extracted seismic section, so that the fault interpretation of the seismic section is effectively navigated; (6), under the navigation of the fault plane interpretation, seismic sections are extracted in a rolling mode in the direction perpendicular to the fault strike step by step, and the fault interpretation of the seismic sections is finished until all the seismic sections of the fault is finished; (7), the steps (3)-(6) are carried out repeatedly until interpretation of all faults of the whole area is finished.
