摘要:
 
黑帝庙浅层气藏大多数气井仅有生产动态数据而无测压资料，应用传统物质平衡法、弹性二相式法等无法评价气井动态储量。收集气藏特征、流体性质参数，产量、压力及井筒完井相关数据，剔除不合理的压力、产量数据，采用垂直管流计算公式，将井口压力折算成井底压力，诊断结果合理准确后，应用现代产量递减分析软件RTA评价井的可动用储量。经对XQ7井和 XQ15井动态储量进行评价，评估储量范围分别为（107～133）×108 m3和（047～055）×108 m3，与物质平衡法和国际SEC准则静态法评估结果基本一致。该方法对无测压资料的气井动态储量评价具有一定的准确性，而对评价产水或存在井底积液的气井尚待研究。
Abstract:
There are only dynamic production data other than pressure data for most of the gas wells in Heidimiao shallow gas reservoir. It is impossible to evaluate gas well dynamic reserves using traditional material balance method and elastic twophase method. The relevant data of gas reservoir characteristics, fluid property parameters, production, pressure and wellbore completion after removing the unreasonable pressure data and production data were used to convert the wellhead pressure into bottomhole pressure by vertical pipe flow calculation formula.  After doing all this, the available reserves of a well with modern production decline analysis software RTA were evaluated. The dynamic reserves of Well XQ7 and XQ15 were evaluated, and the estimated reserves range was (107-133) ×108m3 and (047-055) ×108 m3 respectively, which was basically consistent with the results of the material balance method and the static method from international SEC criterion. This method has certain accuracy for dynamic reserve evaluation of gas wells without measured pressure data, but it is still need to be studied for the evaluation of gas wells with water production or bottomhole fluid accumulation.
