塔河油田凝析气井无阻流量经验公式建立及应用

Establishment and Application of Empirical Formula for Open Flow of Condensate Gas Wells in Tahe Oilfield

塔河油田凝析气井无阻流量通常采用系统试井测试资料,利用指数式、二项式和一点法等确定。但实际生产中并非所有凝析气井都进行系统测试,同时系统测试也对气井生产造成一定影响。为了更合理地对每口单井配产,制定合理的开发方案,通过对塔河油田多个区块凝析气井大量试井资料进行统计分析,认为无阻流量与地层渗透率、储层厚度、地层压力和温度等参数存在较好的相关性,并通过其具有的规律性建立起经验公式来确定无阻流量,为单井合理配产提供了参考依据。

The open flow of condensate gas wells in Tahe Oilfield was commonly determined by using systematic well test data,exponential,binomial and single-point methods.But in fact,not all the condensate gas wells were systematically tested,while the systematcal test would cause influence on gas well production.To have a more reasonable production allocation,make better development program,it was statistically analyzed through the testing data from several wellblocks in Tahe Oilfield.It is considered that the open flow was better correlated with formation permeability,reservoir thickness,formation pressure and temperature,and based on its regulation,an empirical equation is established for determining the open flow,it provides a basis for rational production allocation.
