Maintenance of oil production levels in such deposits is possible through methodological study and development of recommendations for optimizing and improving the development system, targeted application of technologies and methods for enhanced oil recovery. In turn, the methodological study for deposits with hard-to-recover reserves includes a systematic statistical and geological and technological analysis of the results of field development, an analysis of existing generally accepted methodologies, and theoretical studies. Thus, the creation of an integrated approach to regulating the development of oil fields, taking into account a detailed understanding of the geological structure, is an important task in the current state of the fields under development.</p> <p><strong>Aim:</strong> The aim of the work is to develop an integrated approach to regulating the development of oil fields with hard-to-recover reserves based on methodological solutions of technological and statistical analysis, differentiation of research objects, retrospective analysis of the use of technologies and methods aimed at increasing oil recovery. The aim of the work is to form an integrated approach to regulating the development of oil fields with hard-to-recover reserves based on methodological solutions for geological-technological and geological-statistical analysis, differentiation of research objects, retrospective analysis of the use of technologies and methods aimed at increasing oil recovery.</p> <p><strong>Materials and methods:</strong> Achieving this goal is possible using the following methods: statistical analysis, geological and field analysis, methodological solutions for studying the relationship "rock fluid", differentiation of research objects according to geological, geophysical and geological and field data. On the example of some stages, research algorithms are proposed.</p> <p><strong>Results:</strong> A methodological solution is proposed for regulating the development of oil fields with hard-to-recover oil reserves.</p> <p><strong>Conclusion:</strong> The proposed geotechnological approach to the development control will improve the technological efficiency of hydrocarbon reserves development due to a detailed understanding of the reservoir structure, differentiation into zones (areas) of the reservoir, study and analysis of their state of development, reasonable selection of priority and promising technologies and technical solutions to increase their production.</p>development process modelingpore space structureobject classificationsenhanced oil recovery methodsstatistical analysis of geological datarock wettabilityәзірлеу процесін модельдеукеуек кеңістігінің құрылымыобъектілердің жіктелуімұнай беруді ұлғайту әдістерігеологиялық деректерді статистикалық талдаутау жыныстарының сулануымоделирование процесса разработкиструктура порового пространстваклассификации объектовметоды увеличения нефтеотдачистатистический анализ геологических данныхсмачиваемость породы1.Sultanov SK.
