Abstract:
Improvement of efficiency of oil and gas reservoir development
is directly connected with the reliability of the implemented
development project, characterized by its full adequacy to the
reservoir conditions. Such adequacy in designing the development
of oil and gas reservoirs is most often ensured by providing
comprehensive informativeness of the implemented reservoir
hydrogasdynamic model, even with insufficient information about
the physical and geological characteristics of the model.
Due to the great diversity of these characteristics that directly
affect development indicators, and the need to know them during
the reservoir development process, the said adequacy of the
implemented development project is established by using the
effective algorithms, which maximally take into account these
aspects of providing comprehensive informativeness of the
implemented reservoir hydrogasdynamic model, one of which is
the identification algorithm. The implementation of this
algorithm can identify the physical and geological characteristics
of the reservoir system hydrogasdynamic model being implemented,
using the reservoir development data for the previous periods
(according to the development history). In view of the above,
the article proposes a method for identification of
filtration-capacitative parameters of the relaxation-deformed
reservoir based on the model of real gas filtration in the
gas mode, using data from the development history. This
technique makes it possible to simulate changes (to carry
out identified determination) of permeability and porosity
in all points of the relaxation-deformable gas reservoir,
as well as to obtain a corresponding gas-dynamic predictive
model of development.
