Gas well productivity is important is an important method for determination of ripen flow potential and working system , prediction of prediction performance and study of related gas reservoir engineering 摘要气井产能评价是确定无阻流量和工作制度、预测生产动态及其它气藏工程研究的重要手段。
When processing of data from single - point test , the value of is generally taken by 0 . 25 for calculating the open flow potential of gas well , and the result is far from that from modified isochronal test 摘要目前，在处理一点法试井资料时，取函数为定值0 . 25来计算气井的无阻流量，其结果与修正等时试井有很大的偏差。
Practice shows the technical renovation has greatly improved thermal efficiency of gas well - type heat treatment furnace , increasing productivity of furnace , achieving objective of saving energy and reducing environmental pollution 实践表明：技改有效地提高了燃气井式热处理炉的热效率，提高了炉子的产量，达到了节能与减少环境污染的目的。
The map shows the similarity between each location in the study area and the location chosen at oil & gas well or dry well , thus it can predict both favorable and poor sectors of oil & gas bearing 统计类比图给出了整个研究区中每一基准点与控制点相似属性的个数，因为控制点一般选为油气井位或干井位，因此，可利用统计类比图进行有利区带和不利区带的预测。
This paper introduces a method for determining average formation pressure in homogeneous gas wells and gas wells with boundary and formation heterogeneity , checked by actual measured pressure value , this method is proved to be simple and effective 本文介绍了均质及存在边界或地层非均质气井平均地层压力的确定方法，经实测压力值检验，证实方法是简易有效的。
