justification Selecting and development field governed by criteria
of rationality.
What is a rational development system? Rational
development system - a system that provides the needs of the state
in the oil at the lowest cost possible and high oil recovery.
In establishing these criteria the following basic points
must be considered:
1. The minimum degree of well interaction.
2. Maximum recovery factor.
3. Minimum production cost.
A rational development plan must ensure the prescribed
production at minimum cost and with the highest possible recovery
factor.
Planning the development system consists of selecting a
variant which meets all the above requirements. On this basis the
problem of establishing a rational development plan should be
subdivided into a number of problems to be solved one after
another:
• establishing the geological-physical data;
• establishing the technical indices for some particular
development plan by means of hydrodynamic calculations;
• evaluating the economic effectivity of the different
development plans;
• choosing the most rational development plan by comparing
the geological- technical and economic characteristics
involved in different plans.
To select rational development field conditions at the
design stage different options for development are calculated.
Options are not only for systems development or by action on the
layer but the parameters for the development of the same systems.
What is the technology of extracting oil from the
depths? The technology of extracting oil from the depths
defined mechanism that drives the oil and gas in the reservoir. In
natural conditions, this oil displacement by water or gas contained
