Abstract: The calculation of minimum allowed production rate of condensate gas well is of great significance in optimization of production tubing size and estimation of bottom-hole liquid loading. According to the fuid flowing and the factors affecting flowing, this paper derivales the equation of minimum allowed production rate of condensate gas well, calculates the minimum allowed production rate in different tubing sizes and botom-hole pressures, analyzed the probability of bttom-hole liquid loading, provides the ltubing sizes of different pressures, varied production rates and the reasonable value of maximum tubing diameter. If bigger than this value, the btom-hole liquid loading will occur, resulting in abnormal production of condensate gas well. Finally, some probabilities of improving the liquid-discharged ability in condensate gas well are analyzed in this paper.

Key words: condensate gas well, production rate, tubing size, bottom hole
