MODELING THE PROCESS OF LIQUID FLOW IN THE SYSTEM "FORMATION–PIPELINE"

A model of the process of nonstationary motion of a liquid in the conjugate system "formation–pipeline" has been constructed, and coupled equations have been solved. An analytical expression has been obtained that makes it possible to determine the infl uence of the law of variation in the pressure at the end of the pipeline and in connections to it on the pressure at the wellbore. Numerical calculations have been carried out at different values of the system′s parameters.
