Abstract: The influence of acid treatment on carbonate reservoirs is analyzed on samples of core. Several genetic types of upper Devonian limestones and dolomites of the Timano-Pechora Province are studied. The investigated acidized samples were saturated colored pitch. The structure of pore space was analyzed in transparent sections. Depending on the rock composition and structure both improved reservoir properties of rocks, and their deterioration was established. It is shown that acid treatment in good re- servoirs can be not effective or have negative consequences, while inferior reservoirs can show improved permeability.

Abstract: Singularities of lineations grid interpreted in the space image of the Suzun gas condensate field (north-west of West Siberia) are considered. The lineations grid was studied by computer (LESSA software) and expert methods. A faulted block structure of the field is proposed which does not contradict the available geological geophysical data but is not allowed for by the accepted field model.

E-mail: biblioteka@nedrainform.ru

Abstract: The first attempt of forecasting the parameters of thermal properties of sand-aleuron rock matrix on the basis of lithological classifications is made. The lithological triangle is recommended to define the average values and the range of heat conductivity variation and a thermal capacity the clastic part of sand-aleuron rock variations. The reliability of the forecast of heat conductivity and thermal capacity values is confirmed by experimental data validating the correlation of thermal properties of the firm-phase of sand-aleuron rock with lithology.

Abstract: The percolation model for electrokinetic flow of electrolyte in porous media is presented. Within the bounds of this model taking into account ionic the solution concentration, zeta-potential, porometric curve and surface properties of porous media the influence of temperature on effective wiscosity was investigated. It is determined that in the presence of sufficient amount of capillaries with radius comparable with the thickness of EDL, the rate of filtration greatly decreases as against the velocity of filtration without influence of EDL, that is interpreted as electro-viscous effect in porous media. The influence of temperature on effective viscosity depends on porometric curve shape: effective viscosity for fine-pore media is more sensitive to temperature change. The dependence of effective viscosity obtained within differs from classic Andrade law.
