Abstract

The invention discloses a complex geological structure seismic fault image processing method based on a fault bifurcation structure model. The new structure of fault bifurcation is introduced on the basis of the two structures of horizon and fault introduced in traditional structural interpretation, which can be easily It can well complete the interpretation of complex geological structures containing reverse faults or even multiple reverse faults, and at the same time improve the accuracy of fault image processing in the interpretation of seismic structures containing reverse faults. The invention aims to solve the technical problems of heavy workload and low accuracy in fault image processing of the horizontal interpretation method for geological structures containing reverse faults existing in the prior art.

Description

technical field

[0001] The invention relates to the technical field of seismic structure interpretation, in particular to a complex geological structure seismic fault image processing method based on a fault bifurcation structure model. Background technique

[0002] Faults play an important role in controlling the migration and accumulation of oil and gas. Therefore, the interpretation of faults is an important content of seismic interpretation. Faults break the stratum into upper and lower plates. The fault in which the disk is relatively descending is mainly formed by horizontal extrusion. The dislocation characteristics of seismic reflection waves near faults are very complex. Therefore, fault interpretation is the key to structural interpretation.

[0003] At present, most structural interpretation software based on earthquakes have solved the fault image processing and interpretation of geological structures containing non-reverse faults well, but for a long time, ther...
