Well log data

This study corrected and supplemented the broken segments, then use the corrected and supplemented curves to calculate porosity. The porosity calculated in this study for 9 wells has been used by JVPC to build the mining production technology diagrams, whle the existing softwares can not calculate this parameter. The testing result proves that the Artificial Neural Network model (ANN) of this study is great tool for correction and supplementing of the well log curves.

The paper deals with non-linear least square algorithm applied to determine simultaneously equilibrium constant pKb or log , activity coefficients of ions HA+ and of neutral molecules fA for aqueous solution of monoprotic bases from pH data at different ionic forces established by inert salts. It has been shown that the calculation results of log HA+, logfA and log as well could be in a very good agreement the not so large number of experimental data when the experimental data are fully treated in order to receive INPUT data with high precision.
