      <abstract xml:lang="ru">
        <p>Представлены результаты лабораторных испытаний по определению коэффициента трещиностойкости KIC горных пород тремя методами для терригенных и карбонатных объектов. Испытания проведены разными методами в связи с отсутствием в России стандартной методики определения характеристик трещиностойкости для горных пород. В данной работе использовались следующие методики определения коэффициента KIC: растяжение образцов керна с кольцевой трещиной, действие сосредоточенной силы на образец-балку с трещиной и метод изгиба полукруглых образцов с трещиной в соответствии с рекомендациями ISRM. В работе представлены связи коэффициента трещиностойкости со скоростью продольной волны и пористостью. Полученные зависимости характеризуют общую тенденцию изменения исследуемого параметра и могут быть использованы при проектировании гидравлического разрыва пласта на месторождениях, для которых были проведены испытания.</p>

        <p>This paper contains the results of laboratory tests to determine the fracture toughness coefficient KIC of rocks for terrigenous and carbonate objects by three methods. The tests were carried out by different methods due to the lack of a standard method for determining the fracture toughness characteristics of rocks in Russia. We used the following methods for determining the KIC coefficient: the extension of core specimens with an annular fracture, the action of a concentrated load on a beam specimen with a fracture and the method of bending semi-circular samples with a fracture according to ISRM recommendations. The paper presents the relationship of the fracture toughness coefficients with the P-wave velocity and porosity. The obtained dependencies characterize the general trend of changing for the studied parameter and can be used in the design of hydraulic fracturing in the fields for which tests were conducted.</p>
