Abstract

For gas well under certain conditions, formation water production is inevitable in the later development; Formation water production is harmful to the normal production, it may cause liquid loading, flooding or even stop production. Based on the study of liquid loading and the rate laws of liquid loading, taking corresponding measures for the gas well is important. Simulating formation liquid production of gas wells with single rate under wellbore conditions, observing and measuring liquid loading rate through the experiment, summing up the liquid loading rate law of wellbore, are significant to the stability of gas well.

Keywords: Airflow carrying liquid, Liquid loading, liquid loading rate.
