DESIGNING METHOD OF VUGGY-PORE OIL STRATUMS Russian patent published in 2008 - IPC E21B43/00 

FIELD: mining.

SUBSTANCE: method includes installation into model with piled up porous medium element imitating interstice, in the capacity of which there is taken doubled or more layered metal lath area and dimensions of which are defined by means of geometrical similarity of modeled stratum interstice. Porous medium between laths is consolidated. Model is leakproof covered, vacuumized and filled under vacuum by water. Water is flushed lengthwise and crosswise of lath location. It is defined penetrability of modeled stratum in these directions and water is displaced by oil model. According to invention at terrigenous rocks modeling with displacement oil by means of water to the metal lath it is preliminarily coated hydrophilous substance. This substance made of high-silica sand milled till fraction close by dimensions to real parameters of modeled stratum. It is cooked suspension on the basis of water glass, salmiac water solution and powdered high-silica sand. Suspension is covered on lath in layers from each side. Each suspension layer is strewed by milled high-silica sand with further suspension baking at temperature 30÷40°C. At that for the first layer it is additionally introduced into suspension 0.05÷0.1 wt % of oil for hydromechanical and hydrostatic drives.

EFFECT: widening of range of practical application for physical modeling of vuggy-pore stratums.
