Abstract
The analysis of 60 samples of kerogen based on statistical data processing pyrolytic parameters (pH and temperature index maximum output of hydrocarbons in the cracking kerogen) is conducted. The paper studies kerogen types and nature of saturation of productive strata by the method of benchmarking and comparisons.
The results of data processing obtained by pyrolysis «Rock-Eval» rock samples from wells of different parts of the Dnieper-Donets basin. The research allowed to evaluate the spatial distribution of different kerogen types and determine the nature of the maturity of organic matter within the individual Straton disclosed wells.
There are confirmed different kinds of mature organic matter from existing oil fields and to the potential gas reserves of unconventional type within the studied structures.
The analysis of the spatial distribution of types of kerogen within the DDD based thermal pyrolysis conversion rock and «Rock-Eval». Installed on certain types of kerogen studied structures coincide with the lateral distribution of hydrocarbons in DDD from north - west to south - eastern part, namely oil deposits characteristic of northern and gradually replaced the condensate and gas in the southern part. In the studied core samples predominant type III kerogen, which according to existing classifications, formed mostly from the remains of terrestrial vegetation and paleoumovah continental margins and deltas.
