1. generating section based on step 4) interrupting layer explanation results, under 3-D view, put down along by the first step in step 4)
The trend for the fault combination that explanation results of the fault interpretation result and second step in face on section are formed, is visually inspected section
It is upper whether smooth with the presence or absence of interpretation of anomaly line and section, judge whether tomography is explained rationally with this；
2. if section is rough, return step 4), correct the fault interpretation on section as a result, to rough fault line into
Row reinterprets, and regenerates section；
3. repeating the above steps 1., 2., until fault plane is smooth, tomography space closure is completed.
8. it is as described in claim 1 a kind of based on the fault interpretation method cuing open flat interaction and being combined with tectonic style guidance,
Be characterized in that, in above-mentioned steps 6) in, utilize above-mentioned steps 3) establish tectonic style library be prior information, with tectonic style library
In classical tectonic style template constraint and instruct the syntagmatic on section between tomography, particular content includes:
The first step, the vertical, horizontal ratio that fixed section is shown, by major profile fault combination sample existing in window comparison window
Classical pattern in formula and tectonic style library, preferably the highest classical pattern of matching degree is used as desired pattern out；
Second step, cutting and syntagmatic based on major faults on desired pattern amendment section；
The desirably bonding relation of fault style, pattern form, the fault style that adjustment practice interpretation goes out go out practice interpretation
Fault style and expectation pattern between difference reach minimum, complete implementing for Profile Faults combination.
