USE OF Rzh = f(Qzh)
MODIFIED DISPLACEMENT CHARACTERISTICS FOR ESTIMATING
THE EFFICIENCY OF MEASURES AIMED AT INCREASING OIL
RESERVOIRS RECOVERY RATE (p. 5)

The article proposes a method for assessing the
effectiveness of measures aimed at enhancing oil recovery (EOR). The method
is based on a modified displacement characteristic (MDC), theoretically
substantiated by the Buckley – Leverett model, linking the liquid-oil factor
with the accumulated liquid production Rzh = a + bQzh.
The notions of a "fixed" reservoir development system (FRDS) and
temporarily "unbalanced" reservoir development system (TURDS) have been
clarified. The transition from FRDS to TURDS is fixed by the bifurcation
point, or "kink" of Rzh = f(Qzh) dependence,
the slope of which determines the "new" mobile reserves that can be
recovered from the reservoir with the full implementation of the introduced
enhanced oil recovery method.
The feasibility of the proposed method
application is proved by experimental and statistical data on the development
of 12 oil production facilities (fields, separate layers, wells).
On the curves of the dependences Rzh
= f(Qzh), built for these objects, the parameters of the
"old" and "new" displacement characteristics (a, b and
at, bt) as well as the point of the beginning of the process, bifurcation (or
timely TURDS) and stabilization of the implemented EOR process are clearly
identified. All possible options for the behavior of modified characteristic
of oil replacement by water (MCR) Rzh = f(Qzh) are
generalized by the ideal MCR Rzh(Qzh) corresponding to
the equation Rzh = a + bQzh.
Keywords: modified
characteristic of oil displacement by water developed by Sipachev – Posevich;
"fixed" and temporarily "unbalanced" reservoir
development systems; bifurcation point; evaluation of the effectiveness of
measures to enhance oil recovery.

The paper presents the results of an integrated
model application when developing a project document for the development of
the Nakhodkinskoe gas field. Based on the results of the calculation made
with the help of the integrated model, the gas production levels for the
asset were predicted for a long-term period (with a planning horizon of 10
years), the recommended option for the development of the Nakhodkinskoye
field was substantiated, which would ensure maximum gas recovery, taking into
account the implemented design solutions and existing restrictions. Regarding
the optimization of the well operation mode, a substantiation of the tubing
diameters was carried out taking into account the predicted dynamics of
reservoir pressure during a field development.
Keywords: integrated
model; development of gas fields; calculation of technological indicators of
a field development; medium and long term planning; tubing diameter;
restrictions during a field operation.

The study of viscous oil recovery from a carbonate
reservoir containing reserves of different densities proved the fact that for
the full oil withdrawal and in order to reduce its viscosity by dissolving
asphalt-resin-paraffin content, it is recommended to inject a water-gas
mixture of "dry" and "fat" gases in the ratios obtained
by technological parameters calculation in field conditions. So, for reserves
with increased density, it is most effective to increase the introduction of
"fat" gas by 6...8 %.
Keywords:
carbonate reservoir; density of reserves; water-gas mixture; gas content.

The article presents the results of laboratory
studies of liquid filtration on the samples of low-permeable core selected
from the AC3 reservoir of the Vinogradov field. The analysis and
interpretation of the research results is carried out. The experimental
dependence of the initial and limit pressure gradients on the absolute gas
permeability is obtained. Based on the sector hydrodynamic model of the AC3
reservoir, calculations were made taking into account the parameters of
nonlinear filtration, determined experimentally. The influence of nonlinear
effects on technological indicators of development is analyzed as well.

the Petroleum Experts IPM Prosper software module (PVT INPUT DATA) in
integrated modeling of oil wells. The module implements the functionality of
accounting for the rheological properties of produced fluids and zones of
their manifestation when performing calculations on an integrated model. On
the example of two wells, the process of taking into account the influence of
the dynamic viscosity of an oil-water emulsion on the operation of a
submersible electric centrifugal pump is described. The process of obtaining
the initial data, introducing them into the software module is described, and
a methodology for assessing the accuracy of integrated models tuning is
presented.

The structural-mechanical properties of
oil-water emulsions in well 130 of the Severnye Buzachi field were
experimentally studied. Based on the parameters measured in the laboratory,
the values of shear stresses on the walls and shear rates were calculated,
and then rheological flow curves were built for various temperatures and
water-oil ratios. As a result of the studies, the regularities of changes in
rheological properties depending on the water content and temperature were
determined, and a formula was obtained that allows calculating the viscosity values
of complex oil-water emulsions based on the oil properties of this field.
Keywords: oil-water
emulsion; properties; rheology; crude oil; viscosity; water; temperature.

Free gas presence in well products produced by
the electric submersible pump (ESP) causes a negative impact on the discharge
and energy characteristics of the pump. The pump may work in the non-optimal
operation area due to the fact that free gas in the gas-liquid mixture (GLM)
flow, increasing its volume, slips in the first ESP stages. Part of the
energy, which is driven to the pump shaft, is irrationally consumed for
compression and subsequent dissolution of gas bubbles in the fluid, resulting
in a decreasing efficiency of the ESP.
Tapered ESP assembly is one of the methods that
are applied to reduce harmful effect of free gas on pump performance. The
first stages of higher flow rate are installed in the ESP housing as
pre-installed modules for pumping out the GLM with a large volume flow rate
of the mixture, its transformation into a depleted GLM with lower gas content
and providing an optimal flow rate of GLM at the intake of classical stages
of the pump unit section. Tapered ESPs are of interest because they require
almost no additional costs. However, there is a difficulty in selection of
tapered units for well conditions.
The results of bench tests of pumps ESP5-80,
ESP5-125, ESP5-200 on the model gas-liquid mixture water–surfactant–air are
summarized. Based on the obtained results, a method for calculating the
deformation of ESP head has been developed and its error estimation has been
made; recommendations on its application in the calculation of the tapered
ESP have been formulated.
Keywords: electric
submersible pump; gas-liquid mixture; tapered pump.

The article demonstrates the decisive role of
studying the features of oil recovery intensification from depleted fields
using nanotechnologies. The development of any oil field is carried out to
the loss of profitability of further oil production. Methods of oil
production intensification are aimed at reducing the time of a field
development and, as a result, increasing its profitability.
The article discusses some methods of improving
and simplifying oil production using nanotechnologies. The use of
nanotechnology in order to increase the return on oil remains an urgent topic
at the moment.
The main trends of this problem solution can be
formulated as size effects in the properties of catalysts, size effects in catalytically
active porous materials; nanotechnologies in separating mixtures;
nanotechnological coatings; use of nano-materials as part of an intelligent
system (various sensors, drives, control devices).
Keywords:
nanotechnology; oil; oil production; intensification; depleted deposits.

The article presents a physical-mathematical
model of the functioning of soil temperature stabilization systems with a
horizontal evaporator. The relevance of the developed model is due to the
need for a qualitative improvement in the methods of geocryological
forecasting of the state of soils of the foundation of engineering structures
with intense heat release during the development of oil and gas fields in the
Northern and Arctic cold regions. On the basis of the solution obtained in
the framework of the heat engineering forecast using the proposed model, it
becomes possible to recommend the optimal configuration of the soil
temperature stabilization system with a horizontal evaporator, the power of
which will be sufficient to keep the soil frozen for a particular object.
Keywords: field
development; frozen ground; temperature stabilization of soils; modeling;
