Methods of Fault Modeling by Well-to-Seismic Integration
Geological structure model is the foundation of the sedimentary faces modeling, property modeling and digital simulation, which includes the horizon model and fault model. Fault model which is accorded with underground conditions plays an important role in the structure modeling, so it would be an important work to build the fault model perfectly with the seismic and logging data. This paper take the fault modeling of C84-6 well area in Chaoyanggou field as an example, building the fault model by four methods of ‘Projection of polygon’ ‘Correction of depth domain seismic body’ ‘Checking by overlooking’ ‘Correction of breakpoints’ by the software of Petrel. The fault model which is built by integrating logging and seismic data can be the skeleton to build the final geological structure model, and those methods mentioned in this paper has been applied to the modeling work in some adjacent areas at present.
