As it is known, the use of complex geological, geophysical and technological information forms the basis of the technological decisions made. The efficiency of well drilling largely depends on the quality of the information received. At the same time, obtaining and using such information requires the parallel use of modern methods of data processing and information analysis. In recent years, a large number of studies have been accumulated on the process of interaction of a rock-cutting tool with rock, which propose methods and means for determining the physical and mechanical properties and abrasiveness of rocks, and ways to use information in assessing their drillability. Experimental studies conducted on core sludge material, studies based on the analysis of geological, geophysical, technological information, as well as those based on classification methods are among them. As practice shows, the use of the results of geological and technological information (GTI) in combination with geophysical surveys of wells (GSW) allows for a deeper study of the section and thereby improves the quality of decisions made. The noted circumstance, as well as the experience of drilling wells and numerous studies indicate the need for comprehensive research based on the use of the results of geophysical and geological-technological research of wells, which also requires the use of appropriate methods of data processing and information analysis. Taking into account the above, the article considers to the analysis of information obtained during drilling, assessment of the drillability of rocks, their classification by section and thereby the preparation of better information taking into account uncertainties in decision making.
