AB  - This article presents the interpretation of Bouguer gravity anomalies using the 3D prism method inthe potentially promising Ajinohur oil and gas region. According to this model, the surface depth of thecrystalline basement is calculated by considering the density contrast at the bottom of the low-velocity zones inthe upper part of the Earth's crust and the quadratic dependence of the density difference on depth.The studyaims to conduct a numerical analysis of the gravity field of the potentially promising oil and gas region ofAjinohur and develop a digital gravity model of the sedimentary layer thickness.For the interpretation of thegravity anomalies in the potentially promising oil and gas region of Ajinohur, a sedimentary basin is viewed as anumber of prisms placed in juxtaposition. The decrease of density contrast in sedimentary basins isapproximated by a quadratic function. Based on the gravimetric field data of the studied area, the gravity modelof the sedimentary layer thickness was constructed using the GR3DSTR computer program.From the gravitymodel of the sedimentary layer thickness, it was found that the maximum thickness is near Ajinohur Lake, in theGamigaya-Ajibulag area (16 km), and the minimum is in the structural area of Aydinbulag, Chaykend, andEastern Dashuz (6-8 km).The sedimentary layer thickness in the area where the Gojashen structures are locatedis 8 km. The regions of negative local gravity anomalies correspond to areas where the sedimentary layerthickness increases, such as in the Gamigaya-Ajibulag area. Conversely, a decrease in the sedimentary layerthickness is observed in the zone of local gravity maxima (Dashuz, Aydinbulag, Gojashen). The correspondencebetween the calculated sedimentary layer thickness with seismic sections and well data was also determined.Thegravity model of the sedimentary layer thickness is of practical importance in oil and gas exploration and inselecting drilling well locations.
