pdf Lithostratigraphical features and the Poro-Perm properties of lagoonal facies rocks of Bukhara step (Bukharа-Khivа oil and gas region)
For the effective conduct of petroleum geological exploration, it is necessary to reliably determine the position in space and time of the reservoirs, which are often composed of rocks of various petrographical compositions and facies. The results of a detailed study of the material composition, structural and textural features of carbonate rocks and their reservoir properties in the zone of development of lagoonal strata on the territory of the Bukhara step of the Bukhara-Khiva oil and gas region, using the example of the Dultepa field located within the Mubarek uplift, are presented. The relationship between the reservoir properties of rocks and the facial conditions of sedimentary environment, obeying the general developing pattern of shelf carbonate accumulation, is considered. The studied patterns of distribution of various genetic types of rocks that compose the strata of the lagoon facies zone reflect the temporal events of the development of sedimentary basins and make it possible to effectively solve theoretical and practical problems of oil and gas geology.

Keywords: carbonate rock, lagoon facies, reservoir properties, Bukhara-Khiva oil and gas region.
