Babko I. The peculiarities of Vizean carbonate's complex formation at Dniepr-Donets Depression's central part and pit petroliferous potential

The geological structure of territory and research interval take in all possible types of rocks and hydrocarbons traps which were studied and continue to be studied in Dnieper-Donets Depression. The consideration of modern state point about principles of petroleum facial control zones revealing and directions of researches at studying lateral stratygraphic-chronological correlations in Vizean deposits of XIV-XIIa microfaunistic will allow to take into account and use the modern achievements of a geological science. The offered sedimentation model allows to reveal natural sequences of the genetic types replacing each other in a direction of shoreline. This model reflect the lateral changes of physical-geographical conditions in which these deposits were formed, and compare to modern sediments not detached facies, and all facial number, that warns of mistakes at paleogegraphic interpretations. The stratification of Vizean stage on productive horizons is given for the first time and by results of researches for two levels of carbonate sedimentation it is offered to divide the XIII microfaunistic horizon to XIIIlow and XIIIupper, according to a new method with the account of carbonate deposits diachrone structures and facial changes. On the basis of new stratifications maps of thikcnesses and spreading of Jablunovskaya and Moshkovskaya suites are constructed, and map of facial changes deposits C1ve1, a new perspective objects for hydrocarbon's searches are distinguished.
