synthetic-seismic-velocity-spectrum's Introduction

Synthetic-Seismic-Velocity-Spectrum

This code is to generate the seismic supergather according to the assumed RMS velocity model. It also conclude the code for semblance spectrum computation.

Preparation

create conda env and install python packages

conda create -n SynData python=3.8
conda list -e > requirements.txt

Generate synthetic velocity with constant SNR

A RMS velocity model is provided to generate synthetic dataset (saved in /model_info/RMS_info.npy)
There is a example generating a few synthetic datasets with SNR=[10, 4, 2, 1, 2/3, 1/2, 2/5, 1/3], respectively.
Run the following codes in shell of Ubuntu system:

nohup python GenerateData.py --DataRoot /mnt/data/spectrum/hade --OutRoot /mnt/data/spectrum/hade-S1 --SNR 10 > Run.log 2>&1 &
nohup python GenerateData.py --DataRoot /mnt/data/spectrum/hade --OutRoot /mnt/data/spectrum/hade-S2 --SNR 4 > Run.log 2>&1 &
nohup python GenerateData.py --DataRoot /mnt/data/spectrum/hade --OutRoot /mnt/data/spectrum/hade-S3 --SNR 2 > Run.log 2>&1 &
nohup python GenerateData.py --DataRoot /mnt/data/spectrum/hade --OutRoot /mnt/data/spectrum/hade-S4 --SNR 1 > Run.log 2>&1 &
nohup python GenerateData.py --DataRoot /mnt/data/spectrum/hade --OutRoot /mnt/data/spectrum/hade-S5 --SNR 0.67 > Run.log 2>&1 &
nohup python GenerateData.py --DataRoot /mnt/data/spectrum/hade --OutRoot /mnt/data/spectrum/hade-S6 --SNR 0.5 > Run.log 2>&1 &
nohup python GenerateData.py --DataRoot /mnt/data/spectrum/hade --OutRoot /mnt/data/spectrum/hade-S7 --SNR 0.4 > Run.log 2>&1 &
nohup python GenerateData.py --DataRoot /mnt/data/spectrum/hade --OutRoot /mnt/data/spectrum/hade-S8 --SNR 0.33 > Run.log 2>&1 &
