文摘

The report is devoted to assessing the impact of petrophysical properties of rocks on the rate of drilling mud lost circulation. The cluster analysis by FCM-method has been performed, 5 clusters have been established, and appropriate fuzzy rules have been formulated. To evaluate the effect of geological conditions on the nature of lost circulation in terms of lack of information, mutual correspondence between indicators of petrophysical properties of rocks and rate of lost circulation has been reached on the basis of fuzzy cluster-analysis, that is very important for the early diagnosis of lost circulation and assessment of their risk.
