生产系统方法实例分析气井产量

多数情况下气井产量的评价和预测,考虑的是从储层到井底即流入部分,并未考虑从井底到井口即流出部分,这样作出的产量评价和预测将会与生产实际发生较大差别,本次将采用生产系统方法,综合采用数值试井技术和井筒模拟技术,在试井解释结果和井筒模拟结果认识的基础上,实例分析下入井下节流器对气井的产量和压力的影响,并在此基础上,分析和预测气井产量变化趋势,并将预测结果与目前气井实际生产情况对比,预测结果和生产实际较好吻合。

Apply the method of production system to gas well case study

The analysis and forecast of gas well production rate always take into account the region which from reservoir to bottom hole,don’t take into account the other region which from bottom hole to well head,because always think the first region,don’t take the two regions as a whole,which will cause difference from reality,this thesis take the view of production system,viewing the reservoir-bottom hole-well head as a hole,integrate the technology of numerical well test and wellbore simulation,on the base of well test and wellbore simulation results,analysis the effect of choke on gas well production and pressure,analysis and forecast the change trend of gas well production,check the simulation result against production reality,there is a consistency between the result and reality,this method is practical.
