GEOCHEMICAL FEATURES OF THE JURASSIC DEPOSITS OF THE SOUTH-EASTERN PART BUKHARA-KHIVA OIL AND GAS REGION

Аннотация

Taking into account the rapidly developing worldwide trend of searching for deposits associated with non-structural traps of oil and gas, the work related to basin modeling is more relevant than ever. It should be noted that the rationality of such studies is primarily based on an integrated approach based on geological, structural, lithological, petrographic, paleographic and geochemical features of the territory. The article presents the lithogenetic features of the facies of Mesozoic deposits. The main regularities of the territorial distribution of geochemical factors confirming the presence of favorable conditions for the generation and accumulation of hydrocarbon fluids are summarized. Mineralogical, lithological and facies characteristics of the formations of Jurassic deposits of the south-eastern part Bukhara-Khiva oil and gas region are described. In order to study in more detail, the degree of enrichment of Jurassic rocks with organic matter, the concentrations of dispersed organic matter and chloroform bitumoid in the section of carbonate sediments were analyzed. To assess the hydrocarbon-producing qualities of the studied deposits, schematic maps of the distribution of average values of geochemical parameters of organic matter were constructed based on the materials of core studies.
