Abstract
This paper presents an analysis the technology for creating an artificial gravel pack behind the casing in the near-wellbore part of the formation in producing oil and gas wells. Gravel-embedding filter is not only a special device installed in the well to clean the fluid extracted from the formation of sand and other foreign impurities, but also the use of gravel in conjunction with the filter in order to retain the formation sand at the site of its occurrence. Wells are equipped with gravel filters when completing them in formations represented by medium to fine grained and silty sands. The desiccant layouts of gravel stuffing filters on lightly cemented sandstones are presented in the work show high efficiency, as they prevent the removal of sand during the well operation. Creating an artificial gravel pack is an effective way to prevent sand from entering the well.
