На основе комплексного анализа кернового и шламового материала установлены геохимические признаки, позволяющие выделять коллекторы и неколлекторы, представленные глинистыми и плотными карбонатизированными интервалами. Определены особенности химического состава генетически различных типов глин – кровельных, внутрипластовых и подошвенных, имеющих близкие геофизические характеристики по данным полного комплекса каротажа во время бурения. Показана возможность идентификации типов глин по данным РФА шлама для оперативного определения положения скважины относительно продуктивного интервала и обоснованной корректировки ее траектории. Установлены геохимические признаки, позволяющие различать природные плотные карбонатизированные интервалы и техногенное карбонатное загрязнение, поступающее в шлам из бурового раствора в виде мраморной крошки. Полученные результаты обосновывают эффективность применения технологии углубленного изучения шлама в ачимовских отложениях Уренгойского НГКМ для снижения неэффективной проходки при бурении горизонтальных скважин как с полным, так и с минимальным комплексом каротажа во время бурения.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents a methodology for the rapid interpretation of X-ray fluorescence (XRF) data from drill cuttings, taking into account the lithogeochemical characteristics of the Achimov Formation deposits of the Urengoy oil and gas condensate field (Russia). Based on a comprehensive analysis of core and cuttings material, geochemical indicators were established that allow reservoirs and non-reservoirs, represented by clay-rich and dense carbonate-cemented intervals, to be distinguished. The chemical composition characteristics of genetically distinct clay types – upper, intraformational, and basal clays – were determined. These clay types exhibit similar geophysical characteristics according to the data from the full logging-while-drilling suite. The possibility of identifying clay types from XRF data of drill cuttings was demonstrated, enabling the rapid determination of the well position relative to the productive interval and informed adjustment of the well trajectory. Geochemical indicators were also established to distinguish natural dense carbonate-cemented intervals from carbonate contamination introduced into the cuttings from the drilling fluid in the form of marble chips. The results demonstrate the effectiveness of enhanced drill cuttings analysis in the Achimov Formation deposits of the Urengoy field for reducing non-productive drilling during horizontal well construction, both with a full and a minimal logging-whiledrilling suite.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ачимовская толща</kwd><kwd>рентгенофлуоресцентный анализ</kwd><kwd>буровой шлам</kwd><kwd>элементный состав</kwd><kwd>литогеохимия</kwd><kwd>геонавигация</kwd><kwd>горизонтальное бурение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Achimov formation</kwd><kwd>X-ray fluorescence analysis</kwd><kwd>drill cuttings</kwd><kwd>chemical composition</kwd><kwd>lithogeochemical</kwd><kwd>geosteering</kwd><kwd>horizontal drilling</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Деркачев А.Н., Николаева Н.А., Можеровский А.В., Григорьева Т.Н., Иванова Е.Д., Плетнев С.П., Баринов Н.Н., Чубаров В.М.
