За счет использования косвенных данных удается существенно снизить погрешность прогноза. Прогноз может строиться как для отдельных скважин, так и для межскважинного пространства, что позволяет создавать геологические разрезы прогнозируемых свойств и 3D-модели их распределения. Для доказательства эффективности рассматриваемого подхода проведены численные эксперименты на данных из стратиграфического диапазона георгиевской и васюганской свит Казанского месторождения на юго-востоке Западной Сибири. Сравнение полученного прогноза с реальными, неизвестными при его выполнении, значениями моделируемой переменной показало высокое качество модели с коэффициентами детерминации до 0,9.</p></abstract><trans-abstract xml:lang="en"><p>The spatial variability of properties in sedimentary deposits can be assessed using approximation methods. A small number of direct measurements or their extremely uneven distribution leads to significant model errors. This article explores the possibility of using multidimensional approximation and regression splines, both considering spatially referenced direct observation data and using well log curves statistically linked to the modeled variables. It is possible to significantly reduce the forecast error by utilizing indirect data. The results can be computed for individual wells as for inter-well space, allowing for the creation of geological cross-sections of predicted properties and 3D models of their distribution. In order to demonstrate the effectiveness of the proposed approach, computational experiments were conducted using data from the stratigraphic range of the Georgievskaya and Vasyuganskaya formations in the Kazan field in southeastern West Siberia. Comparing the obtained forecast with the real, unknown values of the modeled variable at the time of its implementation showed a high quality model with determination coefficients up to 0.9.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>петрофизический прогноз</kwd><kwd>каротаж</kwd><kwd>многомерные сплайны</kwd><kwd>регрессионные сплайны</kwd><kwd>трехмерные модели</kwd><kwd>геофизические программные комплексы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>petrophysical forecast</kwd><kwd>well logging</kwd><kwd>multidimensional splines</kwd><kwd>regression splines</kwd><kwd>threedimensional models</kwd><kwd>geophysical software packages</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках научной темы FWZZ-2022-0009 «Цифровые геолого-геофизические модели и оценка перспектив нефтегазоносности осадочных бассейнов Арктической зоны Сибири и республики Саха (Якутия); усовершенствование геолого-геофизических методов исследований» Государственной программы ФНИ.
