Annotation:
Drilling of horizontal wells in carbonate reservoirs is accompanied by significant difficulties associated with various geological features. Within the field under study there are zones of local increase of effective capacity and reservoir characteristics (filtration-capacitive properties) associated with the distribution of ring structures (RS). The authors of the article present the results of studying the RS geological features and using multi-attribute analysis to solve problems of mapping the RS boundaries with differentiation of zones by properties, optimizing the laying of wells horizontal sections and increasing the efficiency of drilling.
