Annotation:
When developing objects with hard-to-recover reserves, physical-chemical methods of enhanced oil recovery (EOR) are especially relevant. However, the range of such methods and technologies for low-permeable and high-temperature formations remains very limited. The article presents the results of pilot tests of a new technical solution to increase the coverage of the formation by flooding and intensify the development of poorly drained interlayers in such a reservoir. The object of the study is a complex technology for an injection well treatment by a polymeric gel-forming composition and a surfactant-containing oil-cleaning agent. Experimental work carried out in conditions of low-permeable high-temperature formations of a number of fields in Western Siberia proved quite good results of oil recovery increase. The technology is recommended for industrial implementation.
