ANALYSIS OF THE RESULTS OF THE RESTORATION AND CORRECTION OF THE DENSITY PROPERTIES OF ROCKS
In the process of applying petrophysical data for seismic inversions and qualitative binding of seismic data, two things are very important: the availability of acoustic and density logging data in a set of GIS methods in the wells and, if available, the assessment of the quality of the materials and their suitability for solving the posed tasks. Usually one has to deal with old wells; that is why the density and acoustic logging material is often of poor quality and not recorded for the entire wellbore. Therefore, it is required to assess the quality of the initial acoustic and density logging curves, to correct the indications of the used methods, and to restore the curves in the intervals of their absence. In the article, the analysis of the results of restoration and correction of density characteristics in terrigenous sediments by various methods based on reinterpretation of borehole materials was carried out. A comparison of the results of predicting the elastic properties was made. The good convergence of the obtained synthetic density logs by the component method was shown. A comparative analysis of the calculated synthetic density logs was performed using the basic methods of synthesizing. The advantageous aspects of the component method were revealed in comparison with the Gardner-Castagna technique.
