Determination of the Gas Stream Flow Rate When Conducting Hydrodynamic Studies of Wells (Part 2)

Abstract

The review and analysis of the formula suggested in scientific technical literature for calculation of the compression ratio of gas stream passing through a diaphragm in the critical flow mode were conducted. The basic assumptions were formulated which lead to its incorrect determination and directly introduce the error in the calculation of the medium flow rate. The analytical solution id is suggested for obtaining a reliable value of the compression ratio of gas stream passing through a diaphragm in the critical flow mode. A practical approval of the obtained analytical solution is presented
