Zusammenfassung:FIELD: data processing.SUBSTANCE: disclosed solution relates to methods and systems for computer-aided processing of specialized data for providing the process of tracking well drilling. Disclosed method of combined tracking of drilling process consists in performance of stages, at which: obtaining input data of the developed well, including at least data of inclination measurements, GIS data and core data; obtaining logging data of at least one support well; generating, based on said input data and logging data of at least one support well, a combined model displaying rock characteristics and predicting the well borehole position; determining at least one planned path of drilling direction of the developed well based on logging data of at least one reference well; performing calculation of at least one synthetic logging curve based on said combined model and at least one planned path of drilling direction of the developed well; constructing a preliminary model of stability of the well bore, based on determined at least one trajectory of the developed well and calculated at least one synthetic curve; based on the constructed preliminary model of the borehole stability the planned trajectory ensuring maximum well drilling within the target interval and stability of the well shaft; obtaining parameters during drilling of the developed well, characterizing the survey, GIS data and drilling parameters; said combined model is updated and the process of the developed well is controlled based on the updated combined model.EFFECT: high accuracy of simulating the process of borehole drilling within the target interval with monitoring stability of the well bore.7 cl, 18 dwg Заявленное решение относится к способам и системам компьютерной обработки специализированных данных для обеспечения процесса сопровождения бурения скважин. Техническим результатом является повышение точности моделирования процесса проводки скважины в рамках целевого интервала с контролем устойчивости ствола скважины. Заявленный способ комбинированного сопровождения процесса бурения скважины заключается в выполнении этапов, на которых: получают входные данные разрабатываемой скважины, включающие в себя по меньшей мере данные инклинометрии, данные ГИС и данные керна;получают каротажные данные по меньшей мере одной опорной скважины;формируют на основании упомянутых входных данных и каротажных данных по меньшей мере одной опорной скважины комбинированную модель, отображающую характеристики пород и пр
