摘要
通过气井产能方程可以得到气井无阻流量,确定气井的工作制度和预测气井的生产动态。气井产能方程有压力平方、压力和拟压力3种表示方式。实际应用中,这3种形式的产能方程使用比较混乱,没有统一的标准。通过分析气井不同形式产能方程的原理,提出了它们在具体应用中的适应条件。并在用生产数据进行验证的基础上,对在实际生产中产能方程的选择提出了建议。
By the deliverability equation for gas well,we can obtain the absolute open flow and determine working system of gas well and production performance of predicted gas well. The deliverability equation of gas well is expressed in three different forms： pressure-squared, pressure and pseudopressure. In practical application,the application of these deliverability equations has been in a mess without unified standards. By analysis on fundamentals of different deliverability equations for gas well, the conditions of their application are proposed. The different deliverability equations in different circumstances are tested by production data,and selected in real production data.
