Abstract
Accurate characterization of reservoirs is a great difficulty in the study of carbonate reservoirs. Characterization of reservoirs shall be firstly based on the geological recognition of carbonate reservoirs, including multiple reservoir quality-related geologic features such as structure evolution, sedimentary diagenesis environment, reservoir rock types, etc. Taking NT oilfield in the east margin of the Pre-Caspian Basin as an example and starting with the characteristics of carbonate sedimentary facies and sedimentary microfacies, this paper has determined the sedimentary facies characteristics of all layers of carbonate reservoirs in the research area. The lower KT-Ii reservoir in the oilfield mainly belongs to open platform deposits, where intraplatform beach microfacies, algal reef microfacies and interbank sea microfacies are developed. The middle MKT reservoir belongs to a shallow sea shelf environment, where about 400m thick clasolite formation has been deposited. Because of frequent tectogenesis and large sedimentary environment variation, the upper KT-I reservoir includes B layer belonging to open platform deposits, layer mainly belonging to open platform depositions and restricted platform deposits, and A layer belonging to restricted platform deposits and evaporative platform deposits from bottom to top, where grained clastic beach, dolomitic flat, limestone flat, gypsum salt lake and lagoon microfacies are mainly developed.
