Выявлено, что качество пород-коллекторов определяется тремя основными факторами: 1) седиментационным – преобладанием в составе отложений кокколитофоридовых известняков; 2) степенью вторичных преобразований пород в катагенезе – уплотнением и перекристаллизацией; 3) интенсивностью развития трещиноватости.</p></abstract><trans-abstract xml:lang="en"><p>The article describes the results of lithological and petrophysical investigations that would be a base for characterization of reservoir rocks in Upper Cretaceous deposits. These investigations include thin sections description, SEM and NMR analysis. As found that three main factors have constrained final quality of reservoir rocks: 1) depositional settings favorable for coccoliths and chalk sedimentation; 2) late diagenesis changes – compaction and recrystallization degree; 3) fracture intensity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>верхнемеловые отложения</kwd><kwd>Восточное Предкавказье</kwd><kwd>мелоподобные известняки</kwd><kwd>поровотрещинный коллектор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Upper Cretaceous deposits</kwd><kwd>East Caucasian region</kwd><kwd>chalk limestones</kwd><kwd>pore and fractured reservoir rocks</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Борисенко З.Г., Данилин В.П., Литвинов С.А.
