is achieved due to penetrating of water in the oil reservoir or by
pumping water from the surface. The theoretical basis for the
calculation of development is discipline “Underground
hydrogasmechanic“.
The modern designing of oil and gas fields calls for
simple calculations using licensed software and powerful
computing facilities. However, simple models that we consider
enable quality results quickly without long calculations based on
more complex models.

3.1.1 Schematization terms of development

Oil deposits have in terms of irregular geometric shapes,
and usually have a complex geological structure and the irregular
configuration, the thickness of the reservoir is inconsistent in size,
unequal is and properties of the reservoir (porosity, permeability,
oil saturation) variety may be the properties of oil on different
parts of the deposit. This complicates the calculations in the design
development of oil fields. The development put the wrong
geometry analytically cannot be calculated accurately. For the
approximate solving of this problem possible approximation of the
actual deposit shapes such forms or parts of forms that are
subjected to analytic calculation. In the calculations have to be
subjected to the schematic design conditions, use model layer and
liquid filtration processes in porous media. From the degree of
approximation to the real conditions of the model depends on the
accuracy of technological parameters of field development.
When selecting and evaluating design options using
simple models, the calculation of technological parameters for the
selected option - a complex that specified as the receipt of
additional data field when drafting the development.
Schematization is performed in four stages:
- schematization form deposit;
