№ 3 (108) март, 2023 г. ABSTRACT This article discusses the construction of a three-dimensional geological and geophysical model of the Alan gas con- densate field, including the process of building a digital three-dimensional geological model. And also in this article, a lithological model of the Alan gas condensate field is considered, which turns off the rescaling of the logging results and a lithological model in the context of the Alan gas condensate field. АННОТАЦИЯ В статье рассмотрены вопросы построения трехмерной геолого-геофизической модели газоконденсатного месторождения Алан, в том числе процесс построения цифровой трехмерной геологической модели. В данной работе также рассматривается литологическая модель газоконденсатного месторождения, который выключает в себя ремасштабирование результатов ГИС и литологическая модель в разрезе месторождения. Keywords: gas and gas condensate fields (GCF), gas-hydrodynamic studies (GDT), digital three-dimensional geological model, lithological model, GIS, upscaling. Ключевые слова: газовые и газоконденсатные месторождения (ГКМ), газогидродинамические исследова- ния (ГДИ), цифровая трехмерная геологическая модель, литологическая модель, ГИС, ремасштабирования. ________________________________________________________________________________________________ Currently, gas is produced in Uzbekistan mainly Alan gas condensate field: reef and non-reef.

To build a facies-lithological model The lithological model implies the distribution of reservoirs based on the results of logging interpretation, a discrete and non-reservoirs in space. The reservoir properties NTG curve (reservoir-non-reservoir, (Fig. 2) was obtained. 60
