Статья посвящена проблеме нефтеотдачи мезозойских залежей нефти месторождений Грозненского нефтяного района, которые подразделяются на две основные группы. К первой группе относятся верхнемеловые залежи, которые имеют трещиновато-кавернозный коллектор и представлены известняками. Ко второй группе относятся нижнемеловые (аптские) залежи, имеющие трещиновато-пористые коллекторы и представлены песчаниками и алевролитами. Приведены сведения по коэффициенту извлечения нефти (КИН) по ряду месторождений Грозненского нефтяного района. Даны рекомендации по размещению эксплуатационных скважин с целью эффективного их использования. The article is devoted to the problem of oil recovery of the Mesozoic oil deposits of the fields of the Grozny oil region, which are subdivided into two main groups. The first group includes the Upper Cretaceous deposits, which have a fractured-cavernous reservoir and are represented by limestones. The second group includes the Lower Cretaceous (Aptian) deposits with fractured-porous reservoirs and are represented by sandstones and siltstones. The information on the oil recovery factor (ORF) for a number of fields in the Grozny oil region is presented. Recommendations are given for the placement of production wells in order to effectively use them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
