- W2354652808 abstract "According to coal seismic data,C3 coherent technique has good detectability of coal bed's fine faults,but the results is easy affected by random noise.On the other hand,the Spectral Decomposition of S-Transform can improve the resolution of seismic data and suppress random noise.So we combined them together and formed a new technology to make a better interpretation of coal bed's faults.In order to validate the feasibility of this technology,we utilized both forward modeling sections and actual 3D seismic data.At first,we established a geological model containing a single coal bed,and obtained its forward modeling section.After that,10% random noise was added into this section,and we achieved a new section containing white noise.Then,C3 coherences along coal bed's reflection of all sections,including seismic sections and their ISO-frequency sections,were extracted along coal bed.By comparing the C3 coherences of forward modeling section and its ISO-frequency section,we found that the interpreted fine faults of coal bed from ISO-frequency section have higher reliability and precision than normal seismic section.Comparatively to seismic section containing white noise,the detected fine faults from its ISO-frequency section with middle-high frequency were not seriously affected by random noise,and basically avoided the false anomalies of C3 coherence.After applied above method to actual 3D seismic data on 15301 workface in Jilin-2 coalmine,we also found that the ISO-frequency section with middle-high frequency has better identifiable ability than normal seismic section in fine faults detecting.That is to say,in relatively simple condition of coal geological structure,fine faults which fault throws are less than 3m are detectable by middle-high ISO-frequency section.By underground validating,the precision and reliability of interpreted fine faults are acceptable and reasonable.On the contrary,when geological conditions of coal-bearing strata are relatively complex,it is very hard to detect these kinds of fine faults.Thus,some further research is necessary.In a sum,the joint technique of spectral decomposition and C3 coherence can improve the detecting precision and reliability of fine faults of coal bed.However,it is still a long way to go to fully identify the fine faults which fault throws are less than 3 m." @default.
