一种简便的凝析气井合理产量确定方法

不同开采时期合理调整凝析气井的产量，可使地层中凝析油的损失减小，提高凝析气的采收率。凝析气井合理产量的确定，是提高凝析气田经济效益的关键性问题。文章应用系统分析的思想，以井底为节点，以单井整个开采系统为研究对象，通过流入、流出以及最小携液量曲线的分析比较，确定出凝析气井的合理产量，该产量应保证井底积液最大程度地携出。实例论证了该方法的简便性和实用性，对实际生产具有现实指导意义。

Simple Method to Determine Reasonable Production Rate of Condensate Gas Wells

Adjusting production rate of condensate gas wells properly in different recovery stage can minimum the loss of condensate oil and improve the recovery factor of condensate gas wells. It is the key to improve the economic benefit of condensate gas fields to determine reasonable production rate of condensate gas wells. Based on the systematic analysis theory, taking the bottom-hole as the node and the whole recovery system of a single well as the study object, by comparing the inflow and outflow production with the curve of minimal liquid-carrying volume, the reasonable production rate of the condensate gas well is determined. The rate can make the cumulated liquid in the bottom-hole being carried out as much as possible. With real cases, it is proved the method is simple and practical, which has guiding significance for real operation.
