Today the regular Institute seminar was held. In the seminar of the Institute of Mathematics and Mechanics of ANAS doctor of technical sciences, associate professor Abbasov Elxan gave a talk “Movement of a gas-liquid mixture in the reservoir-pipeline system, taking into account heat transfer”.

A model of non-stationary movement of a gas-liquid mixture in the reservoir-pipeline system when a new source is connected to the main line is constructed, taking into account the heat exchange process between the gas-liquid mixture flow in the riser pipe and its environment, and solutions to boundary problems are given. In the first approximation, the influence of changes in the rheological properties of the gas-liquid mixture depending on temperature on the dynamics of its movement is determined. Analytical formulas have been obtained that make it possible to determine the dynamics of pressure at the bottom of the well and the productivity of the reservoir depending on the parameters of the system. Numerical calculations are carried out for practical values ​​of the system parameters.
