SOME FEATURES OF THE STRUCTURE AND DEVELOPMENT OF VEREY HORIZON OF THE MIDDLE CARBONIFEROUS ARLAN OIL FIELD

摘要

The article presents a brief description of Verey horizon of the Middle Carboniferous to Arlanskoe field northwest of Bashkiria. The article presents a brief lithologic-petrographic characteristic Vereisk horizon of the Middle Carboniferous in northern Arlan deposit northwestern Bashkortostan. A description of the main lithotypes yugomashevskogo limestone deposits with cavernous-fractured reservoirs. On the roof of the tier Sakmarian marked inherited from the underlying structure of the regional precipitation – Monocline shallow dipping north-east slope of the surface with a gradient of 4-5 m / km. Here, on the site Veniaminovskom AI Shotaro and AM Malyarenko (“BashNIPIneft” and “Geostra”), in 2012 a group of local uplifts marked with an amplitude of up to 15 m and share their narrow troughs and saddles. Many of these structures may be promising in the accumulation of hydrocarbons and are perceived by us as the search objects in the Middle – term. We also consider the current system development and offers geological and technological measures to increase oil production. The article shows the dynamics of the main indicators of technological development Vereisk horizon. To retrieve valuable information from it about the porosity reservoirs in inter-well space, fracturing and saturation, must be attached to the quality properties of the rocks, some of the wells. Standard GIS techniques are not enough. Methods are needed density and sonic logs of longitudinal and transverse waves, pulsed neutron logging, etc. Technology, which are referred to in this article as the leading GIS technology.
