Several Key Links of Well Logging Data in Well-seismic Joint Inversion
LI Mou-ji · Journal of Oil and Gas Technology · 2014
In the process of oil and gas exploration and development,the seismic exploration was the most important means of oil and gas field exploration and development,the comprehensive analysis and interpretation of logging data were the key link of oil and gas exploration and development. While the well-seismic joint inversion was the important way for improving oil and gas exploration and development based on geology and sedimentology. The joint inversion was fuse process of logging and seismic data. The inversion result was not ideal,the key was that the logging and seismic data were not unified effectively. The process of well-seismic joint and issues of the consistency of logging data were expounded emphatically. It is proposed that the consistency method of standard mudstone frequency distribution is used to correct logging curves to remove the errors of logging curves induced by detecting difference,thus the logging data would be optimally matched with seismic data for improving the result of seismic inversion.
