Полученные экспериментальные данные совместно с результатами геофизических исследований скважин и данных о гидроразрыве пласта были использованы для расчета напряженно-деформированного состояния массива горных пород. Вычисление величин горизонтальных напряжений выполнено с применением пороупругой модели Итона, в которой предварительно были определены коэффициенты деформации на глубине проведения гидроразрыва породы. Минимальное горизонтальное напряжение было определено как давление смыкания трещины гидроразрыва, а максимальное горизонтальное напряжение вычислено по диаграмме напряжений (совмещение критерия разрушения породы и классификации тектонических режимов). При реконструкции напряжений использовались упругие модули, полученные по лабораторным исследованиям. В результате вычислены величины основных главных напряжений вдоль разреза скважины, и определен тектонический режим, действующий на данном месторождении. Получены уравнения зависимости для прочностных свойств пород, слагающих разрез, и вычислены значения прочности вдоль всего ствола скважины. На базе полученной геомеханической модели рассчитана зависимость давления гидроразрыва от длины трещины и оценены условия неконтролируемого роста трещины.</p></abstract><trans-abstract xml:lang="en"><p>   The paper presents the results of laboratory studies of the physical and mechanical properties of carbonate rock cores from one of the oil fields in the Republic of Tatarstan. The experimental data obtained, together with the results of geophysical studies of wells and fracture data, were used to calculate the stress-strain state of the rocks. Horizontal stresses were calculated using the Eaton poroelastic model. The deformation coefficients at the depth of hydraulic fracturing were preliminarily determined. The minimum horizontal stress was determined as the fracture closure pressure, and the maximum horizontal stress was calculated from the stress diagram (combining the rock failure criterion and the classification of tectonic states). The elastic moduli obtained from laboratory studies were used in the stress reconstruction. As a result, the values of the stress along the borehole section were calculated and the tectonic regime was determined. The dependence equations for the strength properties of the rocks composing the section were obtained and the strength values along the entire borehole were calculated. The geomechanical model was used to calculate the dependence of fracture pressure on fracture length and to assess the conditions of uncontrolled fracture growth.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>карбонатная порода</kwd><kwd>геомеханика</kwd><kwd>геомеханическая модель</kwd><kwd>лабораторное исследование керна</kwd><kwd>гидроразрыв</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbonate rock</kwd><kwd>geomechanics</kwd><kwd>geomechanical model</kwd><kwd>laboratory core testing</kwd><kwd>fracturing of rock</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Минобрнауки России в рамках соглашения № 075-15-2022-299 о предоставлении гранта в форме субсидий из федерального бюджета на осуществление государственной поддержки создания и развития научного центра мирового уровня «Рациональное освоение запасов жидких углеводородов планеты»</funding-statement><funding-statement xml:lang="en">The work was carried out with the support of the Ministry of Education and Science of Russia under agreement No. 075-15-2022-299 on the provision of a grant in the form of subsidies from the federal budget for the implementation of state support for the creation and development of a world-class scientific center ‘Rational development of liquid hydrocarbon reserves of the planet’</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дубиня Н.В.
