Study on Sensitivity of Plunger Characteristic Parameters to Gas Well Production

Plunger dewatering gas extraction is a technology primarily used for low-yield natural collection. To maximize the efficiency of plunger extraction, optimization design necessary. This study based on principles lifting extraction. By calculating distribution fluid and pressure in wellbore during plunger's upward movement at startup, as it reaches wellhead, well shut-in, interconversion relationship between liquid discharge, self-jet flow, shut-in recovery processes analyzed. An algorithm developed. When impact characteristic parameters production, considers effect compressibility factor varying with temperature pressure, which makes research results more realistic. The findings this contribute to optimizing process enhancing production.
