Model for Nonsteady Water Removal from Horizontal Gas Wells

Abstract

The paper considers the process of removal and accumulation of liquid in horizontal trunks of gas wells and land gas pipelines. A mechanistic model of the process is constructed, an equation is derived that describes the dynamics of the process of removal and accumulation of liquid, criteria for the removal of liquid are determined, as well as the main dimensionless factors that affect the nature of the process. A method for static analysis of the area of stable operation of a well is proposed. The results of the work can be used in designing the trajectories of projected horizontal gas wells, to evaluate the operation parameters of actual wells and gas pipelines, and to plan measures for cleaning horizontal gas wells from liquid.
