Digitalizacija in interpretacija karotažnih diagramov premogovnika Velenje

Zrimšek, Dominik (author), Vižintin, Goran (mentor)

Digitalizacija karotažnih diagramov je dolgotrajen proces, pri katerem je treba poznati geologijo območja in karotažne meritve, ki so se opravljale na vrtinah. Naloga magistrskega dela je pretvorba analognih podatkov karotažnih meritev v digitalno obliko ali drugače, izvesti je treba digitalizacijo karotažnih diagramov. Karotažne meritve, ki smo jih podigitalizirali so: kaliper, gostotna in nevtronska karotaža, mikrolog, laterolog, gama karotaža, lastni potencial ter dolga in kratka normalna upornostna karotaža. Digitalizacija karotažnih diagramov se izvaja v treh programih. V prvem, Get Data Graph Digitizer, se določijo vrednosti posameznih karotažnih diagramov, te se nato uredijo v programu Excel. Podigitalizirane karotažne diagrame smo zatem interpretirali v programu Strater. V tem programu smo lažje določili in interpretirali lastnosti posameznih geoloških plasti in njihovo lego v sloju na pridobivalnem prostoru Premogovnika Velenje. Glede na literaturo se pojavljajo nekatere razlike, saj se sloji pojavljajo v kombinacijah in zaradi tega nastanejo neskladnosti v primerjavi z literaturo. Podatke smo pridobili iz sedmih raziskovalnih vrtin, na katerih so se izvajale karotažne meritve. V nalogi smo podigitalizirali približno 50 analognih karotažnih diagramov. Rezultati digitalizacije karotažnih diagramov so predstavljeni po posameznih vrtinah v programu Strater.

• Title: Digitalization of well logging data in coal mine Velenje

Abstract

Digitalization of well logging data is a time consuming process and it is required to be familiar with the geology of local area, geophysics and theory of well logging data that were measured in the boreholes. Primary task of master thesis is a transformation of analog well logging data into digital well logging data. Well logging measurements that were digitized are: caliper, density log, neutron log, microlog, laterolog, gama log, self potencial log, long and short normal induction log. Digitalization of well logging data was performed in three different computer programms. First program that was used is Get Data Graph Digitizer. With the following program you can determine the values of well logging data. These values are then arranged in computer programme Excel. With the Excel files finished or arranged, the digitalization can begin in Strater programme. Well logging data is interpreted in the mentioned programme, because the programme is easy to manage. The features of boreholes, well logging data and the geology of individual borehole are displayed in Strater. Layers vary from each borehole to borehole because of the various combinations of layers and that can effect on the measurements of each well logging data. Well logging data were acquired in the Coal mine Velenje from seven exploration boreholes. In the master thesis, 50 different analog well logs were digitized. Results of the digitilization is demonstrated in the programme Strater.
