Abstract

Comparative analysis of sedimentation conditions for the Hauterivian (IX ledge) and the Aptian (VIII ledge) sediments was realized according to the data of grain-size distribution using cluster analysis. (These sediments belong to the most significant Zimne-Stavkinsko-Pravoberezhny and Velichayevsko-Kolodezny oil fields of Velichayevsko-Maksimokymsky oil-and-gas accumulation zone.) The aim of the research is to prove possibility of hydrocarbon reserves growth due to involving in production operation of these missing oil-and-gas bearing intervals and parts of production ledges (the Aptian and the Hauterivian age). In order to do that, according to the built cumulate curves, the median diameter and Trask's degree of sorting were also determined; Rukhin's genetic diagrams were built; paleohydrodynamic levels (Muromtsev's method) were defined; the cluster method was used to group investigated objects formed in different sedimentation conditions; maps of indicators of sedimentation conditions were also made and analyzed. Realized research allows one to indicate the most perspective areas for the supplementary exploration; and also it has been discovered that the algorithm of cluster analysis helps to optimize volume of graphical constructions and increase effectiveness of areas prediction for oil-and-gas collectors distribution.
