Abstract:

With the deepening of unconventional petroleum resource exploration, such as tight oil, shale gas and so on, especially the large-scale horizontal well deployment, the accurate identification of micro-faults is more important than before. According to the characteristics that diffusion filtering technique can enhance seismic events lateral continuity and suppress noise at the same time, make the offset point more clear, and the feature of micro-fault is very obvious in narrow-frequency seismic data, the authors proposed a frequency division coherence method to identify micro-faults. The spectral decomposition technology based on matching pursuit is more suitable for the characteristic of a non-stationary seismic signal than the conventional short-time window Fourier transform spectral decomposition technique. This paper proceeds the corresponding improvement to make it more efficient and more accurate: adopting adjustable parameter Morlet wavelet to establish time-frequency atom dictionaries, using second-order differential complex trace analysis method to get three instantaneous parameters with high resolution, and giving the concrete implementation steps. The application of actual data shows that the frequency division coherence technique is clearer and more accurate for the identification of micro-faults comparing with the traditional coherence technique, and even more preferable for the geological information such as a river channel boundary and a lithology development zone. It provides more geological information for unconventional petroleum resources exploration (for horizontal well drilling and the large scale fracturing) and will play an important role in the development of the remaining oil with high containing water.

Key words: frequency division coherency enhancement, matching pursuit, horizontal well, complex trace analysis, micro-fault
