Abstract

The article presents the key performance characteristics of the acid composition developed in the laboratory «Enhanced Oil Recovery» of the Mining University. This composition can be used during operation of the wells drilled the low-permeable high-temperature terrigenous reservoirs with high carbonate content. The authors describe the algorithm of developing an acid composition and then give its main physicochemical parameters. The degree of drilling mud's filtrate influence on the filtration reservoir characteristics of some oil and gas condensate field in West Siberia was determined by the results of laboratory studies. The authors studied the ability of the developed acid composition to restore and improve the permeability of a reservoir after exposure with process fluids. There is a description of the injection technology of the developed acid composition within the field.
