SPECIFICATION OF ROCKS DISTRIBUTION IN AB<sub>1</sub><sup>1-2 </sup>FORMATION OF SAMOTLOR FIELD
The article considers methods of specification of rock-collectors structure and distribution in AB!1"2 formation of Samotlor field based on data of geological-statistical sections (GSR data), the results of which provided specification of distribution of collectors with different lithological characteristics along a vertical and a lateral. This procedure allowed developing maps of separate typical inter-layers. The first inter-layer is a "clay ryabchik" and a "real ryabchik", the second interlayer is a "sandy ryabchik", the third interlayer is a "real ryabchik", the fourth interlayer is a "sandy ryabchik", the fifth interlayer is a "sandy ryabchik" and "argillaceous sandstone and siltstones". Application of maps developed for choosing technology of oil replacement provides raise if efficiency of oil resources recovery.
