Airflow capability with liquid in gas well
Liquid loading in gas wells is a significant production obstacle for natural gas wells as production declines,resulting in the continuous decline of gas flow rate.Therefore,the liquid-carrying ability of gas flow changes constantly,bringing about difficulties to timely adjust the well working schedule or to take the measures of drainage.In order to figure out this ability promptly,the author establishes the model of flowing and static liquid flow,and makes modifications through indoor experiments.Using on-site data of Sebei gas field,the two modified models are tested and verified,of which the relative errors are very low and are applicable.Meanwhile,for the practical convenience of operators on site,the airflow capability with liquid can be plotted under different key parameters.
