GAS ANCHOR PERFORMANCE ANALYSIS FOR SUCKER ROD PUMPING WELL

This paper analyzes the influence of gas and the use of gas anchor in a pumping well on pump volumetric efficiency (Ve) from the Ve Point of view, establishes the functional relation of the pump volume tric displacement rate (Pd), pump intake pressure and the real liquid production at surface while using the gas anchor, calculates and analyzes the performance of a pump and gas anchor, presents the application time and the improved percentage of the pump efficiency by using it. Based on the established functional relation, the Ve and the required Pd can be calculated directly, or the total liquid production rate at surface can be calculat ed indirectly. The analysis results showed that this method has a great significance for the production of oil wells in the presence of gas.
