چکیده:

For a very long time, multi-phase flow did not appear to be a major issue in petroleum
operations, since it was restricted to local applications on short length surface transfer
lines. But oil and gas producers have very soon observed in their wells and flowlines that
large hydraulic instabilities may occur under multi-phase flow conditions. Multi-phase
production systems are quire complex but prediction of their behavior is essential for
successful design and operation of production facilities. Multi-Phase models can be
broken down into three distinct categories: Steady State Correlation, Steady State
Mechanistic and Transient Mechanistic. Refer to field data analysis mechanistic steady
state and dynamics simulation models, rather than empirical correlations, are widely
used and recommended for design of multiphase production system including well,
pipeline and downstream installations during flow assurance studies. An extensive
validation methodology is proposed here by using real pipelines and wells data. The
evaluation of these point models demonstrates that the TACITETM and OLGA2000TM
models can be applied to any configuration of pipelines with acceptable accuracy.
