摘要
气井产能分析在气田开发过程中起着十分重要的作用,其目的就是得到适合气藏的产能方程,气井产能分析主要分为气井产能测试、气井产能分析两个阶段。气井产能测试以气体的稳定渗流理论为基础,目的是确定气井的产能方程和合理的生产制度,预测气井产量随着气藏衰竭而下降的方式。文章介绍了系统试井测试、等时试井测试和修正等时试井测试、一点法测试等测试方法;针对不同的产能测试方法得到的测试资料,采用不同的产能分析方法对资料进行解释与处理,从国内、国外两个方面介绍了产能分析研究方法。
Deliverability analysis of gas wells plays a very important role in the process of gas field development and is aimed at establishing a deliverability equation suitable for the gas reservoirs. Deliverability analysis of gas wells is carried out in two main steps, i.e. deliverability test and analysis. Deliverability test of gas wells takes the stable filtration theory as its basis and is aimed at defining the deliverability equations and rational production schemes for gas wells and predicting the production decline of gas wells along with the depletion of gas reservoirs. Several testing procedures are introduced in this paper, such as systematic well testing, isochronal well testing, modified isochronal test, and single point test. Different deliverability analytical approaches are used in the interpretation and processing of the test data acquired with different deliverability test approaches. The deliverability analytical approaches at home and abroad are introduced separately.
